Blink Wire Multiple LEDs - The easy way! STEM101.ORG A Non-Profit K-16 Education Program
Fewer wires = Fewer mistakes More wires make for more chances to make a mistake in wiring. Use this technique to wire each LED using only ONE jumper wire. Start by wiring the (+) power rail to 5V and the (-) power rail to GND. STEM101.ORG A Non-Profit K-16 Education Program
Plug the resistor into the (-) power rail and a terminal strip. It doesn't matter which terminal strip you use. STEM101.ORG A Non-Profit K-16 Education Program
Plug a LED (short side) into the same terminal strip as the resistor. The long side of the LED goes into a different terminal strip. STEM101.ORG A Non-Profit K-16 Education Program
Jump from the long side of the LED to a digital output. Any digital output 3-13 will work. Just make sure you program the correct one! STEM101.ORG A Non-Profit K-16 Education Program
Repeat this process for up to 10 LEDs! Here's an example with 4 LEDS. STEM101.ORG A Non-Profit K-16 Education Program
