Walmart lawn chair abject failure - in Lesson 22 the servo is using the only 5V pin on the R4 UNO. Now I need to add the potentiometer but as per Lesson 12 that needs a 5V pin as well. Not risking frying my R4 by experimenting, so will have to head for the next lesson to find the answer... great lessons by the way.

Hi Paul Here is my homework for lesson 22. It's only 44 seconds long so I hope you (& The Guys) will take the time to watch it even though I can't leave a link.

Can u please do arduino lessons on the elegoo 37 sensors kit V2.0 arduino, i wanna learn how to do them and i cant find good tutorials but then i knew who the best tech tutor is. love ur lessons btw

GREAT lesson! Than You!

Thank you Paul!

Good day, I am Engineer. Your series on Arduino has made me a better Engineer. I would appreciate if you could start a series on ESP 32, because you have a unique way of teaching which is very very good. Thanks. Have a nice day. Cheers

he won't because of too many variations, as he has stated.

I don't have time to post the video before the class on Thursday, but I am posting the code without the servo code. I will finish the circuit over the weekend and post it with the video. Notice that the equation of the line does not go through the (0,0) point but has a negative intercept. That is because the potentiometer subtends an angle of more than 180 degrees. // 23 potServo.txt int potPin= A2; int potVal; int br= 9600; int waitT= 100; int angle; void setup() { // put your setup code here, to run once: pinMode(13, OUTPUT); pinMode(potPin, INPUT); Serial.begin(br); } void loop() { // put your main code here, to run repeatedly: digitalWrite(13, LOW); potVal= analogRead(potPin);delay(waitT); angle= .254*potVal-56.134; // This is the line with a Y intercept Serial.print("potVal: "); Serial.print(potVal); Serial.print(" Angle: "); Serial.println(angle); delay(waitT); }

Thanks for the lesson! HW done but I will not make a video since I can no longer link to it here.

So sorry. Really frustrating to be tagged by a machine, and no way to explain. Anyway, thanks for watching and working on the lessons.

Cool video.

Hello... I have a bunch of arduino stuff. I have to buy a new set of arduino's things to follow this course? But i have tinkercad just in case...

This problem has been solved. Read the reply below. HELP: Last night I was working with R4 and put power in the wrong place. Not only did the R4 stop working but four other Arduinos are failing to load programs after clean compilations. They show that port is grayed out. I think I have destroyed a library. How can I remove both the old Arduino IDE and the new one so that I get a clean set of libraries?

I have SG90 servo motors, they just spin continuously. Don't know if the Sunfounders are any different?

Hey Paul!

👍

Hi, I have watched your past videos on auduino r3, I kinda just want to know that how to make your famous cold coffee.

I make two very strong shots of espresso, and while they are still hot, pour them over ice. The hot coffee melts some of the ice, dilluting the espresso to a wonderful rich strength. Try it.

Sir, can you start a new series for esp32?

I hope I’m correct in saying, at a basic level you can do exactly what you can with Arduino R4 UNO it uses the same IDE and uses the same language.

Isn't it better to power the servo using an external power source?

Indeed, but these small servos are OK to power from arduino.

@@paulmcwhorter are you gonna make a tutorial on how to power multiple servos with an external power supply? I cant figure out how I would power the Arduino and the servos, cause they need different voltages

I got the video done before the class, but it is done without sound. kzread.info/dash/bejne/modt14-nqM6WiZM.html
