1.10.2 Using Button Inputs to Control RGB Lights and OLED Display

This example shows how to use a button press to trigger the RGB lights and OLED display on the sheenbot∞. When Button A is pressed, a message is shown on the OLED, all three RGB lights turn on, and then switch off one by one with a delay.

Follow the logic below to understand how this interaction is structured:

• Check if Button A is pressed
• If pressed:
  • Display "Button A" on the OLED
  • Turn on RGB LED 0 (yellow)
  • Turn on RGB LED 1 (cyan)
  • Turn on RGB LED 2 (red)
  • Wait 1 second, then turn off RGB LED 0
  • Wait 1 second, then turn off RGB LED 1
  • Wait 1 second, then turn off RGB LED 2
  • Clear the OLED display line

• Check if Button B is pressed
• If pressed:
  • Display "Button B" on the OLED
  • Turn on RGB LED 0 (green)
  • Turn on RGB LED 1 (red)
  • Turn on RGB LED 2 (orange)
  • Keep the pattern active briefly
  • Turn off all RGB LEDs
  • Clear the OLED display line
