The H2HC 2015 Badge is basically a customized Arduino Leonardo . As such it can be directly programmed from all Arduino compatible IDEs. It is important to note, that the H2HC 15 Badge is run at 5V.

Pin Out

When working with the Arduino IDE all pins can accessed the way they’re enumerated on the PCB. Due to the re-design the pins and the enumeration changed. The following lines of code list the pin names the way they are on the Badge.
