Thank you!!!!! This is the first course I' ve found that explains what each component is. I knew I was supposed to use resistors but didn't know why and now I get it 😊 I'm glad I finally found a true beginner course.
I've been doing electronics for 45 years let me add my 2 cents worth 1. it's really cool that you're getting into electronics STICK WITH IT 2. My advice.... Electronics and I.T. and Technology has a funny way of complicating things...

THIS IS A GOOD COURSE NO DOUBT Now let me start anew post
😊 I hope you enjoy the course! I want to thank freecodecamp and everybody for the support. Anyways, if you have any ideas for future courses, let me know in the comments.
Thanks Mathew it really help Please make one more video of Arduino with more projects with more different components such as how to use gsm ,relay , etc will be waiting for next part And also make same video on rasberrypi too
This was an amazing video. I learned so much about arduino. this video may have changed my life. Thank you on so much next time I would enjoy more projects it would be so amazing.
Arduino makes this easy, and guys, this is not "from scratch", all of these projects are using external libraries, if you hard code this, AKA actually knowing C, and Assembley, it would be totally different.
Mathew, from an instructional design perspective, your set-up with using the arduino as a power source and then the battery was excellent. Yes, the battery works but...was a great way to set up learning. Outstanding.
This is wonderful material and I continue to watch it because of its comprehensive list of topics and beginner orientation... but: I understand that repetition is key in education, but this is youtube, where repetition can be accomplished by the student, by rewinding. The teacher's habit is to repeat virtually every phrase, both technical and conversation-fillers, at least once and often 3-4 times. I looked back at one intro, perhaps for temperature sensors, and what could have been a 15-second intro was fully 4 minutes. Please, give this wonderful content the finish it deserves and have it edited down to the barest information... probably cutting it to 2 hours. Thanks.
Great Content. Simply Great!! In Project #6, I may have missed the part about being careful of frying up your LED. Please be careful of the potentiometer, and not bring down the resistance all the way to 0 and avoid the mistake I did.
Project#8: For people wondering how to import the pitches.h: - Explanation is right after the code source of the Melody Tune of "Play a Melody using the tone()" page. :)
Project#9: DHT Sensor The code in the video didn't work. I rewrote it here ``` #include #include #define DHTTYPE DHT11 #define DHTPIN 13 float tempC; DHT dht(DHTPIN, DHTTYPE); void setup() { Serial.begin(9600); dht.begin(); } void loop() { // put your main code here, to run repeatedly: tempC = dht.readTemperature(); Serial.print("tempC: "); Serial.println(tempC); delay(1000); } ```
I'm a little surprised and honestly sceptical that you didn't consider the forward voltage of your LED in the very first circuit. Now obviously your resistor did it's job but wouldn't you have to use this equation to calculate the proper resistance for your led? PowerSrc V - Fwd V LED = 15ma * R I'd love to see some clarification of this, thanks
If you were to subtract every "ok", every "what" and every instant repeat of the same question/statement from this video it'd be les than half it's runtime. I appreciate the time and effort it took to put this together but damn it's hard to listen to without getting seriously annoyed.
Dude taught me how to use a breadboard when I wasn't even here for it and honestly all the other people that explained breadboards never actually did a demonstration with explaining it just rushed through like you could understand
2:38:22 you have the file right in front of you.. just create a file called pitches.h (with notepad its fine), and copy those 93 lines of code, just a bunch of #define to define all pitches, there... and place it in the library folder
2:17:34 let me correct you You are wrong again, it is NOT AC current for the passive buzzer, it is a flickering/pulsating DC current (turning ON and OFF, it is NOT not same as alternating)! AC means that the voltage/current changes polarity. A PWM signal typically is a logic signal that turns on and off. So, a PWM signal is more accurately described as a pulsed DC signal. It is neither AC nor DC, but it is closer to being DC in waveform, the electricity flow is always going the same direction, it just turns on and off (pulsating). If you set it to 255 it's like a normal 5V DC, but if you set it to 0 Volts, so it's like no current. Anywhere between only changes how long the pulses are on/off. (e.g. 127 -128 will result a 50-50 pulse of 5V and 0V resulting an average 2.5V but NOT AC).
If a voltage is varying from say 5v back to 0V, back to 5v back to 0v, then it is ALTERNATING between 0 and 5 volts. Is this not correct? t's not steady voltage. It's ALTERNATING. So what about a pulsing voltage that alternates between 0 and 5 volts makes it not alternating. All you say is that it's not correct w/o explaining why...when it sounds exactly like it's alternating.
I'm not sure if it's just me - the audio seems out of sync with the video when he explains silicon and semiconductor. A bit confusing for me as I have no electronics background. Nonetheless, nice video to start with. Thanks.
This is a really great course with one tiny constructive criticism: in future videos, please avoid repeating any word in such excessive frequency as you use *"what?"* so often that it becomes extremely redundant, disruptive, distracting, and generally difficult to watch.
In the resistor example, he took the resistor value from 5v and the current for the led. But didn't he have to first substract the voltage of the led and then count the resistance to the voltage over the led limit? So 5v-2v is 3v. 3/0.015= 200ohm
thanks for the content... a couple of feedbacks (am 3 hours and something in): some sections a bit rushed and not quite to the point i.e. how to interpret the pushbuttons and use them as actual switches... also it seems you keep connecting the sensors to the input device pins (potentiometers, pushbuttons) rather than controlling the sensors form different pins using the values from the outputs which to me is a more elegant solution... It would have been nice to see a quick recap with the simulator if possible... I have a microcontroller but got lazy and preferred using the software... Also the explanation why the DHT uses digitalread is not clear in my opinion. How then the sensor can i fact send temperature and umitidiy values which are not binary more efficiently then as analog? Ok probably the library takes care of it but what is the advantage if any?
at 2:08:00 shouldn't you put a little 330 / 220 resistor between the pot meter and the led? if you turn the knob fully to that 0 resistance , won't that 5V fry the LED ?
it is exactly what happened to me ! 🥲bye bye led ! at least it didn't affect other components and this lead me to read more about ohms law to better understand what happened! But I agree this should be mentionned !
Please enable in the settings the ability to translate your video into another language using AI, if possible. In the Yandex browser, your video is not translated into Russian, but some are translated. Thanks!
Thanks for the content, it' useful, even though i'm not a total beginner,i will build and code the projects too. There are a lot to learn here. Altough probably you could cut the lenght of the video by half if you wouldn't say "WHAT" in every 5 seconds, that's slightly annoying.
guys, should i watch this arduino course or the one from 2 years ago that is 4 hours? i watched 1 hour from the one 2 years ago but found this was uploaded yesterday, what should i do
same thing happend to me ! The second time I tried it didn't happened for some reason but then I didn't want it to take risks and put a resistor ! when simulating the excat same circuit proposed in this video in tinkercad it says the current going trough the led when the potentiometer is not offering any resistance is 446 mA which is a lot higher than the 20mA limit of a led! I would recommend to always simulate your circuits before actually connecting them and really understand ohms law before getting further in this course.
sir please be kind enough to do a video series about pic assembly programming , pic micro python programming , pic basic programming , pic c programming with pic 16 , 18 , 22 ........ etc . thank u for the video sir
Thanks for the course, which is a lot of fun. For the seven seg display: I mean, the diode lets the current flow in one direction, but I don't really get why the diode is neccessary? I tried it and it also works without the diode.
one thing most individuals will quickly recognize, is that whatever Arduino kit you purchase, the resistors provided ARE ALL COLOR BASED IN BLUE! As if the Chinese that made them only had blue pigment available for potting the base filler material. Probably not important, but does screw with the minds of those who grew up learning electronics. At then it was a beige light brownish color. Just saying.
Please can you Create a Tutorial video on Arduino Uno, this is because most people can afford this and it is better for beginners. Love the Tutorial by the way
This is humanity at it finest. I will pay my gratitude in the future by providing open source knowledge to all.

My advice, Jump over to the ESP32
you can run all Arduino programs on ESP32

it's far superior that you'd be crazy not to do it as an engineer

I've been doing electronics for 45 years
let me add my 2 cents worth
1. it's really cool that you're getting into electronics STICK WITH IT
2. My advice.... Electronics and I.T. and Technology has a funny way of complicating things... TRY TO SIMPLIFY EVERYTHING WHILE YOU LEARN ABOUT THINGS, if it makes sense in your head, it'll make sense later when everything integrates
3. Now.. this DOESN'T explain what EACH COMPONENT IS.
there is so much more
Logically, this is how you should learn electronics components
BASIC ELECTRICAL CIRCUIT
(Battery / Power source, Wire, Load / Resistor / Fan etc)
Now the components
AS YOU PROGRESS LEARN WHAT EACH ONE IS
DO NOT SKIP OVER THEM
LEARN TO TEST EACH ONE PROPERLY
to do this Understand the purpose and job of each one
WIRE
Learn about diameters, How it relates to resistance and conductivity.
Test with , Resistance, Continuity
Later with more experience, Voltage and Capacitance
This is a connective component
FUSE
Learn the difference between a wire and a fuse
Test with Resistance and Continuity
This is a protective component
RESISTOR
Research different types of resistors
Test with Resistance
and for run, Test difference resistors with continuity TO LEARN WHY NOT TO USE CONTINUITY ON RESISTORS AND FUSES FOR TESTING
learn the limits of continuity testing and when it applies and when it does not
DIODE
For starters do not worry about Zenner Diodes,
First get a grip on DIODES AND SHOTTKY DIODES
once you have that, then progress to LIGHT EMITTING DIODES
Test with Diode Mode
The Take away here is...
If you have a scope, Put 5V through a diode and pay attention
to the Vf (forward Voltage Drop)
NOW YOU UNDERSTAND SOME BASICS, GRADUATE TO THE OPPOSITES
Capacitor vs inductor
CAPACITOR
Start with Electrolytic and learn about the different types of Caps.
Learn about POLARIZED AND NON POLARIZED DEVICES
Do not test a capacitor with Capacitance mode
LEARN ABOUT E.S.R. (Equivalent Series Resistance)
The take away is a Capacitor Stores VOLTAGE
INDUCTOR
Test with a component tester for the Henry value
but you can use Resistance for the test to see if it's burned out or not
the take away is.... THEY STORE CURRENT in a magnetic field
NOW LEARN ABOUT FARADAY'S LAW OF INDUCTION
LEARN ABOUT TRANSFORMERS
TRANSFORMERS
they are basically 2 inductors
you're going to be testing voltage across the primary side
then Voltage across the secondary side
OK, NOW WE GET A LITTLE MORE COMPLICATED AND ENTER INTO SEMI CONDUCTORS
so now we go into
BRIDGE RECTIFIERS
Learn about Half wave rectification, Full Wave Rectification,
Pulsated DC and DC and AC
then.....
TRANSISTORS
then
MOSFETS
This will cover most of what you will encounter
NOW YOU ENTER THIS WORLD
INTEGRATED CIRCUITS (I.C.'s) which is what gets you to Arduino
Learn about
MICRO CONTROLLER
vs
MICRO PROCESSOR
Definitely Look into ESP32 as it is far superior to Arduino and not much more difficult to program
Also.... if you're interested in fixing things
DEFINITELY LEARN ABOUT SMPS (Switch Mode Power Supplies)
that is what a list of all basic components looks like.
THIS IS A GOOD COURSE NO DOUBT

In the resistor example, he took the resistor value from 5v and the current for the led. But didn't he have to first substract the voltage of the led and then count the resistance to the voltage over the led limit? So 5v-2v is 3v. 3/0.015= 200ohm
Great course! I'll ditto the request for the Raspberry Pi course!
thanks for the content... a couple of feedbacks (am 3 hours and something in): some sections a bit rushed and not quite to the point i.e. how to interpret the pushbuttons and use them as actual switches... also it seems you keep connecting the sensors to the input device pins (potentiometers, pushbuttons) rather than controlling the sensors form different pins using the values from the outputs which to me is a more elegant solution... It would have been nice to see a quick recap with the simulator if possible... I have a microcontroller but got lazy and preferred using the software... Also the explanation why the DHT uses digitalread is not clear in my opinion. How then the sensor can i fact send temperature and umitidiy values which are not binary more efficiently then as analog? Ok probably the library takes care of it but what is the advantage if any?
at 2:08:00 shouldn't you put a little 330 / 220 resistor between the pot meter and the led? if you turn the knob fully to that 0 resistance , won't that 5V fry the LED ?
it is exactly what happened to me ! 🥲bye bye led ! at least it didn't affect other components and this lead me to read more about ohms law to better understand what happened! But I agree this should be mentionned !
You answered all of my questions in my head.Thank you a lot sir.
Entire year of Electronics course in one video :-P Good job!
I am leaving a WHAT? That's right, a like and a comment. Thanks for the tutorial.
Y'all reading my mind ??! always uploading tutos whenever i need one xD
also would love to have a node red tuto ♥
23:33 Rip 🙏 Insect-San, You'll remain in our hearts ❤🙏 One Like = One Pray for the little thing 🙏 👼
very sad moment in this course :(

We need more videos on embedded systems especially on stm32 and Raspberry Pi 4. Please...🥺
I clicked on this video by accident now I'm like 1 hour in and I'm hooked 😮
Really everything was great. However, I could not understand the buttons' explanation
Thanks for the content, it' useful, even though i'm not a total beginner,i will build and code the projects too. There are a lot to learn here. Altough probably you could cut the lenght of the video by half if you wouldn't say "WHAT" in every 5 seconds, that's slightly annoying.
Can an ESP32 be used instead in this tutorial? Are there any relevant changes?
guys, should i watch this arduino course or the one from 2 years ago that is 4 hours? i watched 1 hour from the one 2 years ago but found this was uploaded yesterday, what should i do
Excellent. Enjoyed every minute & will keep coming back for references.
project#8 was funny 😂😂
a big thank you to the creator of this interesting course. Much compliments on your job
Another course on Raspberry pi will also be great
This is way more than paying it forward!
Thank you very much for the absolutely wonderful portrayal of Humanity
20:38 Resisitors have tolerance, the percentage of error (+/- resistance)
how did he connect the led in 2:05:40 without resistor
i did connect it like him and my led got fused
same thing happend to me ! The second time I tried it didn't happened for some reason but then I didn't want it to take risks and put a resistor ! when simulating the excat same circuit proposed in this video in tinkercad it says the current going trough the led when the potentiometer is not offering any resistance is 446 mA which is a lot higher than the 20mA limit of a led! I would recommend to always simulate your circuits before actually connecting them and really understand ohms law before getting further in this course.
It's about time! Thank you!
sir please be kind enough to do a video series about pic assembly programming , pic micro python programming , pic basic programming , pic c programming with pic 16 , 18 , 22 ........ etc . thank u for the video sir
I am lucky today i started to learn embedded last 3 days I am finding sources just i think the morning I need best sources I got on evening.❤

In the resistors section, you say amps instead of ohms.
Thanks man , This course was awesome !
On time 3:00, the parts list shows a 16X16 LED Matrix. I think you meant 8X8,
Yep my bad
much needed & appreciated
thank u
Thanks for the course, which is a lot of fun. For the seven seg display: I mean, the diode lets the current flow in one direction, but I don't really get why the diode is neccessary? I tried it and it also works without the diode.
My guy was wondering why "let" doesn't work while programming in Arduino IDE 😭😭😭
I was looking for this comment 😅
Very easy to learn python and arduino circuits with this video I already am coding a trash sorter
one thing most individuals will quickly recognize, is that whatever Arduino kit you purchase, the resistors provided ARE ALL COLOR BASED IN BLUE! As if the Chinese that made them only had blue pigment available for potting the base filler material. Probably not important, but does screw with the minds of those who grew up learning electronics. At then it was a beige light brownish color. Just saying.
AC is not "alternative current" @2:17:59. AC is alternating current.
AMAZING! The perfect tutorial. Thank you so much.
Please can you Create a Tutorial video on Arduino Uno, this is because most people can afford this and it is better for beginners. Love the Tutorial by the way
I believe you have your horizontal and vertical backwards 🤔 Maybe I'm wrong 🤷♂️
This is such a great resource.
I’m sorry to complain but why do you repeat yourself so much 8:58
Best YT Channel ever ❤
This video has helped me a lot I know how to code arduino circuits with python now
Isn't the led having a voltage drop of about 2 v so the resistance calculated is to big?
