Connect the Servo - BLUETOOTH APP INVENTOR - AGTECH

1. Connect a red wire from the red connection on the Servo to the red row of the breadboard.
2. Connect a black wire from the black connection on the Servo to the black row of the breadboard
3. Connect a white wire from the white connection on the Servo to pin 9 on the Arduino.

Pre-install AI2 Companion app on the Android devices for each group. Test the connection of each device with a laptop.

If you are using the Thinkabit Lab notebook have students complete the following:

Red Wire: red on Servo to red row

Black Wire: black on Servo to black row

White Wire: white on Servo to pin 9

1. The wires keep falling out of the Servo connector

• Experiment holding the wires with your fingers to check the connection and use tape for the final project.
• If bent, straighten the wire with your fingers so the wire goes in further and the red and black wire do not touch.
• Try a different Servo.
• Check that solid 22-gauge wire is used.

2. Don't have red/black/white wire

• While the actual color of the wire does not matter, color coding wires makes it easier to use for instruction.

3. There’s a wire stuck in pin 9

• An instructor or adult can use a box cutter or pliers to remove the wire
• Or, replace the Arduino
• Or, use another PWM pin and modify your code to connect the Servo to the new pin.

4. Wire doesn't have enough exposed metal to connect to the Arduino or breadboard

• An instructor or adult can use the wire cutters to strip the plastic coating off the end of the wire

5. Wire doesn’t fit into the breadboard

1. Use 22-gauge wire
2. Use a different hole in the same row of the breadboard.
