Arduino UNO R4 Lesson11 - Servo Motor | Single-Axis Solar Tracker using Photoresistors

This is the 11th lesson of the Arduino UNO R4 - Ultimate Training series. Joed Goh discusses Servo Motors and Building a Single-Axis Solar Tracker using photoresistors. He also shows how to control a servo motor using 2 different Servo libraries. Then, he explains how to position a servo motor using a potentiometer and a photoresistor. At the end of this lesson, you should be able to create a simple solar tracker using two photoresistors simulating east and west locations and a servo motor to position the solar panel.

Unfortunately the code will not compile on my R4 Minima using the 'PWMServo' library (exit status 1) I've checked all the usual things (boards, ports etc) and all okay, however it will work with 'Servo' library but not smoothly, any ideas?…2 hours later…Problem solved! 🎉 I compared the ‘.CC’ & ‘.h’ files between the PWMServo library I installed via library manager on the Arduino IDE, and the same library via ‘GitHub’ and they were different in that the library from ‘GitHub’ contained components for the R4 whereas the other did not, anyway I have installed the PWMServo library from ‘GitHub’ and all is working okay for now! 😁👍🏼

Dear Joed thanks for this course. I have one question. Is it possible to give an working solution of the Challenge Activity ? Thanks a lot and a lot of succes with the next lessons. best regards Bart

I really enjoy your teaching style. I have myself and my students using these tutorials for learning how to use sensors, LEDs, motors, sound and pneumatics for animatronics. You do an amazing job as a teacher. Thank you so much.

Good morning Joed, Sorry to bother you, however I tried to download this file several times and I still got an error "exit status 1" herewith is the error showing on my IDE note: candidate: bool PwmOut::begin(float, float)
bool begin(float freq_hz, float duty_perc);"

Thank you Jeod as per your email I uninstall 1.0.1 and use 1.0.5 and it it work. Thank you very much

I'm trying to control multiple servos or ESCs using the PWMServo.h library but as soon as I attach a second servo or ESC the program doesn't work. Anyone else experience this?

Again I am requesting, How so I contact you, I need some help with esp32 codes . Your new subscriber from Australia

I get the Servo library to work, but not the PWMServo. tried your download from Google drive but still not working. Any ideas what is wrong?. Get error PWMServo.h: no such directory.
in the PWMServo.cpp in section Arduino R4 it is looking for #include <pwm.h>, can't find this library, is this the problem
