Example code for the Programmable High-Power Infra-Red Beacon with display Designed for use with the E-Puck and Pi Swarm robots for swarm research A number of preset frequencies (1, 2, 5, 10, 20, 30, 40 and 50Hz), powers (25%, 50%, 75% and 100%), duty-cycles (10%, 25%, 50%, 75% and 90%) are defined, and the chosen mode can be selected by holding the 'SET' button for 1 seconds, then moving through to the correct menu. Use as a basic structure should other functionality be required from the beacon, such as custom flash sequencies or alternating between the wide- and narrow- LEDs.
