Prepping additional IR sensors and control board

image

As the 3 Sharp IR analog sensors in my robot design consume plenty of power, I’ve created an interconnect module that switches the load on and off by way of a TI nMOS FET. The microcontroller will periodically switch on the load, take a reading of the three sensors via ADC, and then switch the load off again. This process is controlled by  timer-based interrupt, storing the distance reading in a global variable.
