This is how we’re going to hook up an LED
to the circuit board. You’re going to first need the LED, a resistor, and a couple wires
to go from ground to power. To start, your LED is going to have a short wire and a long
wire. The short wire is going to go in ground; This board has a breadboard on it. Hook the
short one onto ground, and the long one will go to the resistor, to this wire, to the 5
volts.When you hook it up correctly, it will light up. If you go directly to 5 volts, you’re
gonna burn it out, so don’t do that.
