Step 4: Power Distribution Circuit
1. Take a red and black wire that has pins on both ends. Cut each in half. You will only use a half of each. You
can save he other halves for backup.
2. Take the red wire and strip the end without a pin.
3. Take the black wire and strip the end without a pin.
4. Take the black wire coming from the 9v battery pack and strip it. Twist the black wire with a pin and the
one from the battery pack together.
5. Input the exposed end of the joined black wires into the
GND
GND port on the L298N motor driver. Secure the
GND port by tightening its screw.
6. Take the red wire coming from the 9v battery pack and strip it. Twist the red wire with a pin and the one
from the battery pack together.
7. Input the exposed end of the joined red wires into the
12V
12V port on the L298N motor driver. Secure the
12V
12V port by tightening its screw.
8. Press the Arduino Nano into the mini breadboard. Make sure the side with
VIN
VIN pin label has three rows of
inputs and the other side two. See the fourth picture for example.
9. Input the black wire coming from the
GND
