7. Examples

7. 1. LED

It is a built-in LED test on the OpenCR board.

7. 1. 1. Code

There are 5 LEDs available in OpenCR, USER1 ~ 4, and the LED connected to base 13 of

Arduino.

USER1 ~ 4 arduino pin numbers are defined as follows. When the corresponding pin is

output as High / Low, the LED turns on / off.

It is a code that sequentially turns on and off all the LEDs.
