WebApr 20, 2016 · The LED needs about 10 mA to light brightly and at that current will have nearly 2 V across it. That means we need a resistor to drop the other 10 V. From Ohm's Law we can calculate that R = V I = 10 0.01 = 1 k Ω so that's what we've got. We'll put three ammeters into the circuit to monitor current at every junction. WebConnect the cathode of the blue LED to ground with a 220Ω resistor. On the other side of the "valley" of the breadboard, connect the anode of the IR LED to the positive rail. Connect the cathode of the IR LED to ground with a 220Ω resistor. If you would like, go ahead and connect your power source and test it out!
