Connect All the Wires to the Servo

1. Insert the white wire into the white wire socket of the standard Servo.
2. Insert the red wire into the red wire socket of the standard Servo.
3. Insert the black wire into the black wire socket of the standard Servo.

Warning: Double check to make sure your wires are in the right place as placing them incorrectly could cause your Servo to break.

STEM Connections

The red and black wires will create a circuit for electric current to flow through the Servo and provide the energy for movement. The white wire will send signals to the Servo with instructions about how and when to move.

Electrical wires are often color coded like this color coding wires minimizes mistakes. In electronics, red is typically used for the positive terminal of the power source, black is typically used for the negative terminal of the power source (or ground, GND), and white is typically used for wires that will send signals to components in the circuit.

The wires keep falling out of the Servo connector

1. Try holding the wire with your fingers for experimenting and use tape for your final project
2. Or, try a different Servo
3. Check that you are using solid 22 gauge wire.

1. Technically the color of the wires doesn’t have any electrical difference, but color coding wires minimizes mistakes. When you’re driving, red means stop and green means go. In electronics, red typically means the positive side of power and black typically means the negative side power.
    
2. Sometimes we like to be dramatic about this step and pretend the students had no idea that red goes to red, black goes to black, and white goes to white by saying “Did YOU know that this red wire goes into the…wait for it… the hole for the red wire?” and wait for the roaring laughter.
