SIMPLE CAR BOT

A simple project for a 2WD bot that can detect and avoid obstacles.

Components

• 1x Arduino Pro Mini 328P (5V/16MHz)
• 1x L298N Mini driver
• 1x HC-SR04 Ultrasonic sensor
• 2x DC Motor 6-12V
• 1x 4 AA Battery holder
• 4x AA Battery
• 2x rear wheel (>4cm diameter)
• 1x swivel caster wheel or ball caster
• 1x rigid 14x10cm base or case of your liking
• wires and stuff

Note: You will need a secondary Uno board or Serial TTL adapter (FT232RL) for example in order to load your sketch on the Pro Mini. Or eventually replace the Mini with a Nano.

Code

1. Include HCSR04 and L298NMini libraries into your project's environment (you can add them as .zip in Arduino IDE "Sketch" > "Include Library").

2. Load car-bot onto the board

3. Done

Note: detect-obstacle and motors-forward are simple examples provided to let you safely test out your components prior to assembling the whole project
