Hello everyone,
I would like to create a circuit that will compare two input voltages and turn a small 1.5V motor on/off accordingly. This sounds like the perfect job for a comparator!
The comparator I am using is a LM339 Quad Comparator from radioshack. All the specs can be found here: http://support.radioshack.com/support_supplies/doc31/31971.htm
I attached a basic drawing of my circuit. (my MS paint isn't working, sorry ) The circuit is currently on my breadboard and is not working. The power supply is a 9V battery. I have no idea why it isn't working, (incorrect circuit???)
If you know what I did wrong please tell me so I can get this circuit to work.
thanks,
George
