RedStick Hookup Guide
Example: The Blink Sketch
The RedStick comes with the blink sketch loaded and running, so the LED (pin 13) will toggle every second. This section shows how to get back to this basic sketch using the Arduino IDE.
To re-load the sketch, select the Arduino/Genuino Uno board from the menu, select the basic example blink, and press upload.
Now compile and run! That's all there is to it!
