Obstacle Avoidance Robot Using Raspberry Pi Pico

Description

we built an Obstacle Avoidance Robot using Arduino. We have planned to make the same Obstacle Avoidance Robot using a Raspberry Pi Pico microcontroller. In this project, I mainly used an HC-05 ultrasonic distance sensor to get the distance sensed immediately and drive the motors separately by the L298N motor driver module. Also, I used a robot car chassis for this project. But you can use a DIY chassis according to your budget.

You can learn how to Interface the ultrasonic sensor with the Raspberry Pi Pico board, please visit this link below.
