I am creating a automatic spraying robot that senses temperature and activates a sprayer and a motor to move the device forward and back.
Thermistor would be linked to an arduino. At certain temperature the arduino would send a signal to the 12V motor to turn on. This motor powers wheels that let the robot move forward and back. The arduino would also send a message to an automatic sprayer to spray.
Any advice on how I can wire this? Power it? Program it?
