Cornell University EE 476 Final Project
Fertilizer Feed Rate Controller
The microcontroller with crystal: the brains of the whole unit.
Takes 5V low current PWM signal from microcontroller and converts to 12V higher current signal.
Takes 12V signal from shaft rotation signals and converts to 5V for microcontroller, as well as providing over/under voltage protection.
Provides power to the radar unit, along with converting the 12V square wave radar output to 5V for the microcontroller, as well as providing over/under voltage protection
Takes 13.8V from tractor battery/alternator and provides clean 12V and 5V power. Also provides fuse protection to circuitry.
