ciarankane123 0:479e94f82332 43 But i will give a brief breakdown of what this simple code entails below:
ciarankane123 0:479e94f82332 44
ciarankane123 0:479e94f82332 45 *Calling for initialisation of mbedded controller on startup whilst all LEDS's on
ciarankane123 0:479e94f82332 46 when inialisation is complete turn off red LED's
ciarankane123 0:479e94f82332 47
ciarankane123 0:479e94f82332 48 *all for menu where you have an option to initialise the sensor or
ciarankane123 0:479e94f82332 49 locate targets whilst red LED's stay on until one is selected using the left and right bumper
ciarankane123 0:479e94f82332 50 then green LEDS on
ciarankane123 0:479e94f82332 51
ciarankane123 0:479e94f82332 52 *If target locate is selected call for targetLocate void to show that a target is being located whilst green LEDS on
ciarankane123 0:479e94f82332 53
ciarankane123 0:479e94f82332 54 *If sensor intialisation is selected then sound piezo buzzer for a period of 10 seconds until sensor is initialised
ciarankane123 0:479e94f82332 55
ciarankane123 0:479e94f82332 56 *If target is found call for Located void with string text and turn on redLEDS and sound buzzer for 5 seconds to indicate target
ciarankane123 0:479e94f82332 57
ciarankane123 0:479e94f82332 58 *After target is located call for results void to display distance from sensor
