- Connect a red wire from Vin on the Arduino to the red row of the breadboard.
- Connect a black wire from GND on the Arduino to the black row of the breadboard.
Remind students that we use a red wire to represent positive power and a black wire to represent negative power.
If you are using the Thinkabit Lab notebook:
Have students complete the following on page XX:
Red wire: Vin to red row
Black Wire: GND to black row
- I don't have a red/black wire
- While the actual color of the wire does not matter, color coding wires makes it easier to use for instruction.
- There’s a wire stuck in Vin/GND
- An instructor or adult can use a box cutter or pliers to remove the wire
- Or, replace the Arduino
- Or, use a different GND
- Wire doesn't fit in the breadboard or Arduino
- Use 22-gauge wire
- Use a different hole in the same row on breadboard
- 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
