Documented Code
Arduino Mega 2560 Code
void setup() {
}
void loop() {
}
This code is a basic template for the Arduino Mega 2560. The setup()
function is where you initialize your settings, and the loop()
function is where the main code runs repeatedly. You can add your specific code to control the LED strip brightness based on the potentiometer's output.
