Project 35 – Touch Screen Light Controller

In this project, you will use the touch screen to turn an RGB LED lamp on and off and to control the color of the LED.

Parts Required

You will be using the exact same parts and circuit as in Project 33 with the addition of an RGB LED. The RGB LED needs to be of the common cathode type. This means that one of the pins is connected to ground (the cathode) and the other three pins go separately to the control pins for the red, green, and blue voltages.
