They are on pins 4 and 5 (OC2 and\nOC3). These have periods of 50ms and on times of 10us. The periods are\noffset by 25ms, with OC2 leading OC3. This allows the ultrasonics to run\nat different times and not interfere with each other. They will run in\nthe background and the echo will trigger an interrupt (already\ncommitted). The interrupt will update an array of distance measurements\nevery 50ms. This continually updated array of distances will be sampled\nfor navigation purposes.","distinct":true,"url":"https://api.github.com/repos/walter91/Mechatronics-Class-Competition/commits/49930e6ecd86014ac9052ef7cd1d1f46add71bf9"}]}
