Hi everyone - It's come to my attention that there has been someone masquerading as myself, responding to some comments here with a link to a Telegram chat to win a prize from me. THIS IS A SCAM, I am not holding a contest, nor do I have a Telegram account. PLEASE DO NOT RESPOND TO THESE MESSAGES!! It's happening on a lot of my videos, I'm taking steps to remove them manually, but as I have 162 videos, it will take some time. If you do run across a suspicious comment, I would appreciate you letting me know at info@dronebotworkshop.com. Thanks! Bill (The real one!)
What I find really amazing about LoRa, is that in the Netherlands, the country with the longest possible dimension of about 335km, they managed to establish communication line over 832 km long. Thanks for the nice video. As always Greetings from NL
Bill, you have created some amazing content over the years and have helped me quite a bit., and I am sure so many microcontroller enthusiasts. I love how thorough you are and the pace you teach at, it is perfect for me! Please keep up the great work. A sincere Thank you is in order!
Originally I was going to do a video about LoRa & LoRaWAN, however it was far too much for one video. I'll have a follow-up LoRaWAN video out very soon.
I'm really looking forward to defcon 2024, is it pretty hard for a newbie to get involved in something like this? I'd love to hear more about how this turned out. Well who knows with any luck maybe I'll run into some kind folks that are willing to help someone who has a very basic understanding of all of this. Literally just got my first pico w in the mail and I was trying to decide what project to take on, and it looks like I found one! Now off to order arduino uno etc. Much love and respect to the community at large! Shareware + decentralization = endless possibilities ❤ tz222zt
Andreas Spiess is the king of anything LORA related. He's got terrific knowledge and has done some incredible things with it. A simple search for his channel will find him. The guy with the Swiss accent!
Fantastic video! I'm currently building a soil moisture monitor using PicoW+Lora E5+capactive soil moisture sensor+microPython+ Home Assistant with MQTT+InfluxDB+Grafana to make decisions on irrigation for growing feed crops.
I am looking to set up a similar sensor array using some of the same tools for an agrivoltaics project. I'm particularly interested in your integration into HA. Could you provide more details about the project?
For some years I’ve been following your content. I’ve always thought it was interesting. But I’ve legit been looking for a video explaining the simplest terms and way to even do this. This video comprehensively makes sense. It makes me excited to order some parts and get going. Hope this helps some at all, albeit not much. Thanks for all the content and being a good steward in teaching us all how to get going.
Thanks! Once again you have inspired me. Great video I’ve been wanting to know more about LoRa and you filled all the blanks for me. Can’t wait for the LoRaWan video.
Great video, but I do have a suggestion. The way you are using millis() for timeout will fail due to rollover. millis() is an 32 bit uint. When it exceeds 0xffffffff it rolls over to 0x0, causing the timeout check to fail after ~49 days. This is obviously not a problem for testing but if someone leaves it running, it will be. You can check by determining if new millis() < old millis(), if so then elapsed time=(0xffffffff-old) + new.
I'm transmitting and receiving data 3.2 km away with a simple spring antenna that came with modules, no clean LOS but still works great, -105 avg dBm so signal is pretty strong. I've just assembled 3rd device that I'll use for reserve and distance testing so I may update this post soon. Lora is amazing
I was waiting for this video after reading your news letter and it didn't disappoint. A BIG thank you for including MicroPython in your video. This really helps me with my microcontroller journey. 📡
Thanks Bill. I was finally able to get some Lora modules working AND I really appreciate that you covered Arduino/C/C++ , MicroPython , and the 3 different microcontrollers. Hope you can continue to do that with all your projects moving forward.
Hi! Do you know if this project work? I'm introducing myself in LoRa comm. Previously I tried Arduino-Raspberry coo, but didn't work. I'll try with 2 Raspberry Pi, to see if I get it successfully.
Wow! I just discovered this channel and it is amazing. Exactly what you need to know in a very professional and explanatory way. Instant subscriber. Thank you!
Nothing short of absolutely brilliant Bill. You are a credit to your country. I can't wait to get started building and programming. Thank you for making such a useful video. Wm.
THANK YOU for not using scrolling code windows on your web site. I absolutely HATE those because when printing, as I always do, valuable web pages to PDF from which the code can later be easily copied and pasted from, the windowed code won't be completely printed and so many sites don't allow the window to be maximized. If they allow listings to be easily copied or if one copies from the scrolling listing, each must then be stored in a subdirectory instead of ALL being accessible in a SINGLE PDF document along with descriptive text.
If you right click the effected section and go "inspect" (or inspect element on some browsers), you can usually tweak the CSS or HTML content to fix the problem.... after some practice, it takes about 30 seconds to fix most unprintable sites. Then just print to PDF (or a printer) as usual.
Such a well timed video as I ordered my first RFM95 devices last week to try out LoRa. Very simple to follow, thorough and informative, as always. Thank you
I think Lora is the basis of a drone controller technology called ELRS, it uses the SX1280 chip to do the data receiving part of controller the drone and then you send the signals into the flight controller to perform the action based on the input
Fantastic. As always very well explained. Something I will be looking into. A good cheap way to keep track of something would be to connect a GPS module as well.
Many thanks for this video, so accurated and well prepared that is better of an university lesson ! One hour is gone so fast and I was glued to the screen all the time, thank you.
Thanks a lot Bill for all your great work. I learn so much! Question: what about doing a video on integrating some of your projects into Home Assistant?
I have learnt so much in your videos that i can start now my own small projects. I'm very thankful and i wish you all the best 🙏👍👍👍 kind regards from Germany 🍀
At 21:00 ground goes to thin filament of LED but when you connect it for real at 24:41 ground goes to thick LED filament as it should. The led at 21:00 should be rotated.
Thanks for the great info. This is really very helpful. I've used the Radiohead rfm95 library before, but the one you mentioned seems to be even easier to use.
Awesome! I just recently heard of this tech thru chatgpt of all things, but I never really looked into actually using it myself until now. Very interesting.
LoRa is a 900Mhz signal so line of site is pretty much what you need between radios. No buildings, mountains, etc. Elevation is used for long distances. If using radios on the ground, 3 miles is considered line of site on a completely flat ground.
Think you for great examples and explanation of LoRa. Im really anxious to see your video on LoRaWAN. I haven’t done any LoRa projects yet. Right now Im trying to figure out what exactly what equipment Im going to order. Encrypted MQTT over LoRa accessible via a cloud broker is my end goal. I hope some MQTT examples my be part of your LoRaWAN video.
Very good introduction I was just looking for 👏 Can you expand the series to discuss security topics? How to protect communication from intercept by others?
Great video. For the wireless transmission part, you chose RFM9X with SPI interface. Have you considered other modules with other interfaces, such as UART or RS485. Maybe, then It can transfer further, like LOS10~20km.
Thanks! Very informative. One question about the payload, is that a standard format? How do you know a packet is actually intended for you ? If your neighbor ran the exact same code would you both process each others packets ? How do you assure unique communication pairs ?
Good question. And one that is quite important to answer, its not just one neighbor but anyone in a 10 block radius... Moreover while I echo the sentiment of many commentators about the pace and quality of your presentations, I am staggered at the effort required to hard-code the OLED display. I think there is some generous use of the term "we" as in "we are going to display two temperatures and two humidity values". Realistically the network needs to be expandable so that "we" are going to be able to receive input from N sensor types and M sensors in each type. Plus the server may need to do computations, for example to calculate the difference of two or more temperatures or report the lower of the humidity readings and may need to set of alarms or visual indications of abnormal conditions and take multiple corrective actions, both at the server or back at the location of the sensors. I see nothing in the code to illustrate how you would do this. Neither is it permanently, or temporarily, logging the time, identity and sensor value, so there is apparently no way to compare yesterday's value at the same time of day or take the sum or average of all readings within the last hour, the last week and so on. Basically unless you are actually looking at the OLED the whole setup is working for nothing. I saw a video today where the designer used png images created in Powerpoint to produce coloured sliders and formatted text boxes to create a really impressive customised OLED display. But, in a day when we are not surprised to find such information on our mobile phone, I think that some of this video promulgates an outdated approach to sensor data and coding for the OLED display. The mobile phone and not an OLED is likely to be at the heart of the interaction between a user and any network of sensors "we" are building, so to me it feels like you haven't really taken this to next-level IoT programming, and you may be training your 500k subs to think in silos. Please don't misinterpret my observations as criticism. Thank you for rekindling my interest in LoRa and Arduino.
You have some really great content and I sincerely appreciate all that you are doing to pass your knowledge and experience on. I do have a request: I have not seen on your videos and perhaps I am just over looking but would you consider adding in where you think the best place you have found to purchase the component you are showing us? Again, you are sincerely appreciated and God Bless.
This has got me excited for a project I want to try where the remots have GPS and track location and speed of 7.5" scale track trains at our train club giving the engineer and idea of their speed but also reporting back to the station the location and speed using LoRa. They travel through a wooded property so I'm excited to see how well it might work in the woods.
I am a car guy with a good knowledge of electronics. You have have some but in blend door actuators use to control hot to cold, the simple ones use a gear driven potentiometer for 0-5Vdc and a dc motor to move and stop anywhere between closed & open. Being one level above cable and vacuum, how would a rotatory dash knob change polarity in the motor? I have 40+ years at dealer but as simple as can be, these controllers on the dash are only $40+ and one circuit board inside. I wanted to control heat / A-C in a 67 C10 pickup. Schematics show a block and call it "Logic". Is this an ardiuno thing or something way more simple that can build myself? Sorry to get off topic but your teaching choice of words are easy to understand. DK, ASE Master Tech since 78, retired. Thanks.
I guess I was hoping for an idea or answer. In the world of "Robots", arms, legs or any part that moves part of the way, stops and moves some more while having the ability to return would fit my needs. It is no different than an "RC" car's steering. Left, right, center or anywhere in between. The problem comes in the controller as it has 6-9 other features costing 20 times the actuator. Just a simple mechanism to move, stop and move again. Maybe they can't make a controller that does that on 12 Vdc with a few wires, not a radio frequency. ASE Master, 78
Hello Bill, thanks for your show, invaluable, would like to know, if it's o.k. to use the R4, with Minima + wi-fi, to achieve long range connections, as you mention in your introduction to this Arduino Circuit. This Circuit is cheaper, and want to get started. Thanks again, watching your show, like going to Class. Loving it..🌹😊
Great video as usual. Thanks. All your examples seem to use the Adafruit module but I want to use the HopeRF module (with Pico/Pico W). Am I correct in assuming that I can use DIO0 instead of G0? What are the other DIO ports and how are they used? Thanks in advance
I see little information on different frequency selection, how to set power output and how to choose the best Spread Factor. I have a number of RFM95W's in use and they work well but I would never get over a KM in range. How do you measure the output power of a LoRa board?
I have been following your channel for a while and think it is one of the best explanations and the code that we can download. I would like some more explanation about the Heltec ESP32 v3 board in the future. I would like to control a relay from one board with push buttons on the other board. maybe you can show us a little more about that. Thank you in advance for all those beautiful videos you make. Kind regards patrick jacobs
I use a cheap esp32 China module(433Mhz) with a build in 18650 battery,..and display ,, no soldering nessesary. I use Aprsdroid app for following the aprs signals. or my Yeasu ftm400 Its very easy to program the module with a callname and some txt
Would be cool to have lora microcontrollers out in the wild powered by solar and mini wind turbines that could make an 'offgrid' online so to speak. The power efficiencey of these things could make them autonomous and have them on for a long time maybe even indefinately which would be handy for emergencies and communication and what not. I was trying to imiagine this with regular low power wifi micrcontrollers but it seems Lora has them beat for range at leaste, speed on the other hand... could a lora microncontroller be able to host a copy of doom2 if the internet goes down for us to download? how about connect and play a game of co-op with reasonable lag? I dont mind waiting all night to download, but the lag should be reasonable under 100ms ping. If Lora can do that, we have made progress!

Thank you Jason, that is very kind of you!
Originally I was going to do a video about LoRa & LoRaWAN, however it was far too much for one video. I'll have a follow-up LoRaWAN video out very soon.
Thanks buddy;
Thirdly would love to learn mesh network with those modules, mostly I see star configuration 😢.
You’re doing such a good work
Please do, do a follow-up with LoRaWAN I would love to make my own
Very interested in a Pi Pico LoRaWAN video.
looking forward your meshtastic video :)
Thank you very much Sir.
A group of us did a 100+ node LoRa Meshtastic cluster at DEF CON this year. I love this technology.
I'm really looking forward to defcon 2024, is it pretty hard for a newbie to get involved in something like this? I'd love to hear more about how this turned out. Well who knows with any luck maybe I'll run into some kind folks that are willing to help someone who has a very basic understanding of all of this.

He is the person that is in this forum who people think knows the most.
I think both of these guys have great content.
This Super Thanks thing is new to me. I'm glad to have an easy way to reward great content creators like you. My students call you the DroneBot Man.
Thank You from the Dronebot Man!
Why don't we people say thanks to library makers! Who makes our code so easy!
Well said
Thanks!
A huge thank you
Yup yup 😊

As a radio ham (VA3MVW) I really liked this particular issue of your vlog, Bill. Super stuff!
I like the way you explain the hardware and software so clearly without getting bogged down with explaining the familiar patterns.
Fantastic video! I'm currently building a soil moisture monitor using PicoW+Lora E5+capactive soil moisture sensor+microPython+ Home Assistant with MQTT+InfluxDB+Grafana to make decisions on irrigation for growing feed crops.

What kind of data rates are you able to achieve?
That's handy to know. That's about the max distance I'd need to run any sensors.
The dronebot workshop intro music is a key part of my childhood memories.
I was waiting for this video after reading your news letter and it didn't disappoint. A BIG thank you for including MicroPython in your video. This really helps me with my microcontroller journey. 📡
I''ve built two of these using LoRa RFM95W, wow super impressed by it, thanks for sharing
Hi! Did it work? Do you have to do any modification?
Thanks Bill. I was finally able to get some Lora modules working AND I really appreciate that you covered Arduino/C/C++ , MicroPython , and the 3 different microcontrollers. Hope you can continue to do that with all your projects moving forward.
Your videos are so well thought out, thorough and easy to grasp. Well done!
Your presentations are just fantastic. All your preparation and diagrams make a complex subject very easy to understand.
Funny how I just ordered two Lora boards and this video popped up. Interested in more pico phyton projects
Been using LoRa for a while now with most my devices.. i love it
Hi! Do you know if this project work? I'm introducing myself in LoRa comm. Previously I tried Arduino-Raspberry coo, but didn't work. I'll try with 2 Raspberry Pi, to see if I get it successfully.
Wow, you covered a lot of ground today. Wish I'd seen this a couple of years ago. Good info and well explained.
Great video Bill… very informative 👌 I’m looking forward to your next videos on LoRa & LoRaWAN 😀
Very nice video! An excellent introduction to LoRa with a lot of background information. I can't wait to see the follow-ups, too!
Wow! I just discovered this channel and it is amazing. Exactly what you need to know in a very professional and explanatory way. Instant subscriber. Thank you!
Thank you so much, and Welcome to the Workshop!
Good ain't.., next step into our Movement of Electrons..🎉❤
Super video, learned more about LoRa in this one video than in several others on other channels
Thanks for doing a video on this! I was just thinking about trying some of these modules out!
Incredible technology. 🤯
Thank you so much for this well made and informative video. 🙏
Can not wait to see the follow ups. 😊
I just love your videos. Top-notch professionalism in every regard. Thank you so much for your effort.
Thanks for producing great informative content and sharing your knowledge with the rest of us. Happy Holidays!🎄

Fantastic.
As always very well explained.
Something I will be looking into. A good cheap way to keep track of something would be to connect a GPS module as well.
Amazing video Bill. You're a professor my friend. Looking forward for your next video.
Awesome explanations and demos as usual. Thank you very much! Looking forward to the LoRaWAN video.
Many thanks for this video, so accurated and well prepared that is better of an university lesson ! One hour is gone so fast and I was glued to the screen all the time, thank you.
Thanks a lot Bill for all your great work. I learn so much! Question: what about doing a video on integrating some of your projects into Home Assistant?
Thank you. I have been planning at least one home assistant video.
Very nice Bill thanks for the video looking forward to more LoRa, you so go the extra mile in more ways than one.cheers Bob
I have learnt so much in your videos that i can start now my own small projects. I'm very thankful and i wish you all the best 🙏👍👍👍 kind regards from Germany 🍀
The LoRa does not use encryption (AES128), but the LoRaWAN does

He put a steel plate between the modules and it still worked. Lora is supposed to be able to penetrate materials much better than 2.4ghz wifi can

Please if you don’t mind. What course did you study at Uni. This is like a mixture of electronics, robotics, etc - mechatronics it seems. Nice!
Amazing video. I skipped the python segment; Not a fan for microntrollers. I love the info and prep this video took.
I would love to see hooking up a e-ink display to receive data and display. For displaying something like weather data to a wrist mounted receiver.
Vielen herzlichen Dank für die super Erklärungen und Beispiele!
Thank you very much for the great explanations and examples!
Please make tutorial on NRF24L1 Module

I notice the Lora boards you linked to are marked 868Mhz not 915. I thought the freq for Canada was 915
Wow. This is impressive. Thank you very much.
Great video as usual. Thanks.
All your examples seem to use the Adafruit module but I want to use the HopeRF module (with Pico/Pico W). Am I correct in assuming that I can use DIO0 instead of G0?
What are the other DIO ports and how are they used?
Thanks in advance
I see little information on different frequency selection, how to set power output and how to choose the best Spread Factor. I have a number of RFM95W's in use and they work well but I would never get over a KM in range. How do you measure the output power of a LoRa board?
Great Tutorial !!!
I have been following your channel for a while and think it is one of the best explanations and the code that we can download. I would like some more explanation about the Heltec ESP32 v3 board in the future. I would like to control a relay from one board with push buttons on the other board.
maybe you can show us a little more about that. Thank you in advance for all those beautiful videos you make.
Kind regards

As usual , a great video !
Could you make a video on Arduino Modbus topic?
Very interesting, as always!
Thank you.
Great video and content. Can the Lora lib be used with a NRF24L01 module as well?
Great video, Sir.
Thank you, glad you enjoyed it!
I use a cheap esp32 China module(433Mhz) with a build in 18650 battery,..and display ,, no soldering nessesary.
I use Aprsdroid app for following the aprs signals. or my Yeasu ftm400
Its very easy to program the module with a callname and some txt
HI Bert, can you share more details of what you are doing? I am interested in similar.

Cool project! Do you know of a guide or tutorial for something similar but, to trigger a relay on the end of it (On the receiving side).
Can we use this for drones?
Great video, thanks!
Would be cool to have lora microcontrollers out in the wild powered by solar and mini wind turbines that could make an 'offgrid' online so to speak. The power efficiencey of these things could make them autonomous and have them on for a long time maybe even indefinately which would be handy for emergencies and communication and what not. I was trying to imiagine this with regular low power wifi micrcontrollers but it seems Lora has them beat for range at leaste, speed on the other hand... could a lora microncontroller be able to host a copy of doom2 if the internet goes down for us to download? how about connect and play a game of co-op with reasonable lag? I dont mind waiting all night to download, but the lag should be reasonable under 100ms ping. If Lora can do that, we have made progress!
The Adafruit RFM95x is expensive and hard to get in Australia. Are there any generics that would be suitable.
