10 LED Fader Project

This is the first of three projects designed to make use of Python and the GPIO pins to control the color of light coming from an RGB LED. The project combines the use of the guizero library to create a user interface and the gpiozero libraries’ PWM feature to control the brightness of the three channels of the LED (red, green, and blue).

Figure 10-1 shows the LED hardware built onto breadboard and Figure 10-2 shows the user interface used to control it on your Raspberry Pi.
