Project description
What is does:?This simple circuit combines three potentiometers to set the brightness for each of the red, green and blue LED's inside an RGB LED. A pushbutton switch is added an an extra feature to turn the circuit on and off. How to build: The RGB Led is wired to PMW pins 9, 10 and 11 on the Arduino. The pushbutton is connected to pin 7 and the 3 potentiometers to A0, A1 and A2. Remember to add a 10K ohm pull up resistor to the ground connection on the pushbutton. For an explanation as to how this works, check out here https://playground.arduino.cc/CommonTopics/PullUpDownResistor Also make…
