Step 1
Put the buttons on breadboard. We're gonna tie one lead of the buttons directly to ground. The other lead will be wired to the Arduino's Digital pins 9, 10, 11, 12, and 13.
Step 2
Put the LEDs above the buttons. Plug the LEDs in with the switches so the Cathode is on the same strip as the side of the button that is tied to ground. And arrange it so the Anode plugs in off to the side of the button.
Step 3
Add 330 Ohm resistor (depends on the LEDs used on the project) and put it inline with the Anode to the top section of the breadboard. Now connect a wire from the resistor to the Arduino.
Step 4
Add the servomotor, wired independently of the rest of components, so tie the red jumper to 5V (for almost all servos), the middle jumper goes in the Digital Pin 9, and the last is tied to ground.
