Arduino controlled Bluetooth-bot

Step 2Wiring connections

Wiring connections
To get a robot running using Bluetooth, there are very few connections. (3) wires to control each motor from the Arduino to motor-controller, (2) wires for the Bluetooth serial adapter to Arduino, the (4) motor wires, and a few power wires. I used male-pin headers to make patch cables from the Arduino to the motor-controller PCB (both using female headers). If you are using the Sparkfun Ardumoto shield, you will not need to wire the motor controller to the Arduino, just the Bluetooth adapter and power.

The L298N motor driver IC uses 3 inputs for each motor (input A, input B and Enable) to determine both speed and direction. Speed control is most easily accomplished by setting the inputs A and B to determine the direction and using the Enable pin to apply the PWM speed control signal.

See the provided wiring diagram for specific connections.
