Hi all,
I'm extremely new to electronics, so this may be a very basic question. I'm working on a tester for electric body cords for fencing competitions. There are 3 leads/wires on a body cord and each wire must register with 1 ohm of resistance or less to qualify in competitions.
I can create a simple continutity tester that tells me whether or not the cord is good ( power, resistor, LED and then close the circuit with the wire being tested), but I have no idea how to turn on the LED if the wire I'm testing has less than 1 ohm of resistance in it. Ideally, I would want a gree LED to light at <= 1 ohm, and a red LED to light at > 1 ohm.
Can someone point me in the right direction for this circuit? Many thanks in advance!
