I just started a new project. It should be an auto-controlled tractor with Mosfet.
Here is more about it. It is pasted here from the code in Fritzing.
// Auto-controlled tractor that can avoid obstacles, the servo is controlled by LDR’s.
// We can start the DC motor with the toggle switch. The DC motor drive the two back wheels.
// The tractor can go just forward.
// We control DC motor with a MOSFET.
// We can set the speed of DC motor with potentiometer.
I made the circuit so far by using a few circuits from here and from there.
Here is the image of the circuit:
Is it good? Did I make some mistake in it?
Should I put another battery just for the DC motor?
