RGB LED

RGB LED#

We will now move beyond simple digital signals and introduce a way to access a range of voltages.

You will need the components listed below.

Component list

  • Raspberry Pi Pico

  • Breadboard

  • RGB LED

  • 3 x 220 Ω Resistors

  • 4 x M/M wires

Using an RGB LED, you will see how we can much more finely tune outputs - in this case to control brightness.

What’s new?

  • More Pulse Width Modulation (PWM)

  • Using random numbers
