How To Use Raspberry Pi Pico W To Control RC Car Robot

Introduction

In this guide, we'll be building a remote-controlled Raspberry Pi Pico W Remote Controlled Car. We’ll also be creating a web server so that we can control the car robot from anywhere in the world!This tutorial will explain how to build an Internet or WiFi Controlled robot using Raspberry Pi Pico W Board. There are a bunch of Robots or Robotic cars from simple ones like Toys to complex ones like industrial Robotic Arms.The wi-Fi-controlled robot can be controlled by a Wi-Fi network. The robot typically has a microcontroller board like Pico w which support Wi-Fi and is connected to a Wi-Fi module or module with the Wi-Fi function integrated. This allows the robot to connect to a Wi-Fi network and receive data from a smartphone.We’ll design a web-based interface to control the robot, that can be accessed on any device(PC or Mobile).

The Raspberry Pi Pico W is a small, low-cost Microcontroller board based on the RP2040 chip and Wi-Fi and Bluetooth connectivity. Pico W is based on the Raspberry Pi Foundation’s RP2040 chip, which features a dual-core Arm Cortex-M0+ processor running at 133MHz, 264KB of RAM, and a wide range of peripherals including ADCs, and digital interfaces like I2C, SPI, and UART.It is designed to be used in embedded applications like robotics, industrial control systems, and more.

The following table shows the connections between the Raspberry Pi Pico W and the L298N Motor Driver.

There are many ways to control DC motors. Here we’ll use the L298N motor driver that provides an easy way to control the speed and direction of 2 DC motors.

The L298N is a popular integrated circuit (IC) motor driver and can control two DC motors or a bipolar stepper motor. It’s commonly used in hobby robotics and other projects that require a motor. L298N breakout board contains two H-bridge circuits, each capable of driving a motor in either direction

The L298N Motor Driver has two input/output pins:

The inputs to the IC allow you to control the speed and direction of each motor independently. The IC also provides protection against over-voltage and over-current conditions.Micropython Code for Pi Pico W Wireless Controlled Robot.The Micropython code for the Raspberry Pi Pico and Wireless-based robot is not difficult.
