Modern and powerful microDot robotics microPython webserver. My heartfelt congratulations for this achievement!
Thank you! 😁
is this working on esp8266 module?
Well done!
Thank you 😁
Hi DonskyTech, Im new to this channel But I Need help! I am able to get the micropython to connect to the wifi and it gives out some IP adresses. I tried ALL of them and nothing seems to work. I know its been a year since this video but I desire help. Please help me before August begins.
no module named utemplate error. i keep getting this error even when i have installed all the required modules
Hey, look at the how to deploy or run section in the writeup found in the description of the video.
@@DonskyTech i had a look and my problem still persists, when i am trying to access the IP address, it saying "refused to connect"
@@DonskyTech and its still throwing me the ImportError: no module named utemplate
what batteries are you using in the video? my car doesnt work as well with 4 AA batteries
Hey it is a 18650 battery. I have released a new video about using the Raspberry pi Pico W wifi car. That is so much better than this. Please subscribe to my channel if you have not done so
Nice job. I will be checking out your code and writeup. Thanks for posting. Did you get the coffees I bought you?
Yes thank you very much. Let me know if something is not clear on the writeup and code.
So I have been messing with Arduino on all flavors of boards for a Decade and even teaching it at our local library. I got into Wifi with esp8266 then esp32 when they came out. I and my students have always had trouble with them connecting to Wifi with about a 25% failure rate even when they are close to the router. Rebooting a couple times usually got them running. I recently have been learning Python and had high hopes for the RP2040 Pico W when it came out. So I got the basic connection example (same code you use in boot.py) from micropython loaded on the Pico W. Same issue. I have tried on 3 networks and still get failures some the time. So my question do you have these problems? Thanks for letting me rant.
@keithlohmeyer122 Hey, there are some usual unsuccessful connections that I have encountered but a usual restart would fix it. The first thing I would check is to verify my Wifi network connection. From my experience, these Microcontrollers or Single Board computers like the Raspberry Pi have trouble accessing the 5G network. This is for routers that have dual-band output where there are 2.4G and 5G bands. Always connect with the 2.4G.
For the ESP32, I often see brownout detector issues when there is not enough power powering it if there are multiple components attached to it.
Another thing for ESP32 also, Wifi does not work when reading analog pins. I forgot the exact problem but I think it has something to do with Channel 2 being used by the Wifi module
