Hands-On Robotics Programming with C++

Wiring connections

The L298N motor driver consists of four input pins, four output sockets (two sockets for each motor), and two sockets for power. The Raspberry Pi pins are connected to the input pins of the motor driver. The DC motor wires are connected to the output socket of the motor driver and the battery snapper is connected to the power socket. The four input pins of the L298N motor driver are labeled IN1, IN2, IN3, and IN4. The output sockets are labeled OUT1, OUT2, OUT3, and OUT4. The following figure shows the wiring connection of Raspberry Pi, motor driver, and motors:

As you can see in the preceding diagram, the wiringPi pin numbers ...
