Blink

This guide will show you how to light up the LEDs on your Maker Uno RP2040. Each digital output pin is connected to one indicator LED. These LED can be  use for input/output troubleshooting and also to make visual effects. 

1. Open the Arduino IDE and make sure the correct board and COM port are selected.

2. Copy and paste the following code to your editor.

3. Verify and Upload the sketch to your Maker Uno RP2040. The expected outcome is to alternately turn on and turn off (blink) the two onboard LEDs (GP0 and GP1) every 0.5 second.
