Block Diagram with Arduino

Jumper from Arduino Nano to Driver Motor

Use PWM pin in Arduino to control motors speed here is the links for Arduino PWM pin and Arduino PWM tutorial

Arduino Nano ------> Driver Motor

• D11 -------------> IN1
• D10 -------------> IN2
• D9 --------------> IN3
• D6 --------------> IN4
• GND -------------> GND
• 5V --------------> 5V <<-------- to power Arduino nano with battery

Block Diagram without Arduino

Jumper from Raspberry Pi GPIO to Driver Motor

here is the link for Raspberry Pi GPIO or type this in Raspberry Pi terminal

pinout

Rpi GPIO ------------> Driver Motor

• GPI0 10--------------> IN1
• GPIO 24--------------> IN2
• GPIO 27--------------> IN3
• GPIO 18--------------> IN4
• GND -----------------> GND

How To Use It

1. Run this code from laptop/PC

play.py

2. Run this code if using Arduino

car.py

or run this code without Arduino

car-without-arduino.py

3. From Raspberry Pi terminal connect to Laptop/PC using IP address
