WebFor each, connect one end to ground and the other to a different digital input pin on the Arduino board, and customize the wire color. HINT: Although you may be tempted to consolidate and use a single resistor for all three LEDs, don't! Each LED needs its own resistor since they don't draw exactly the same amount of current as each other. WebJul 26, 2015 · If the two LEDs are the same colour, using a single resistor will probably work, but the LEDs will be dimmer when both are on than when only one is on. If the LEDs are different colours, only the one with …
