Wiring connections
The ultrasonic sensor's trigger pin is connected to wiringPi pin number 12, while the echo pin is connected to wiringPi pin number 13 via the voltage divider circuit. The VCC pin of the ultrasonic sensor is connected to physical pin 2 (5V) of RPi, and the ground pin of the ultrasonic sensor is connected to physical pin 6 of RPi. The remaining connections are as follows:
- WiringPi pin 0 is connected to the IN1 pin of the L298N motor driver.
- WiringPi pin 2 is connected to the IN2 pin of the L298N motor driver.
- WiringPi pin 3 is connected to the IN3 pin of the L298N motor driver.
- WiringPi pin 4 is connected to the IN4 pin of the L298N motor driver.
- The motor driver's ground pin is connected to the physical pin 3 of RPi.
