# Wi-Fi Robot Car

Day 71 of the 100 Days 100 IoT Projects collection. Board: ESP32.

Drive a 4WD robot chassis from your phone over Wi-Fi with dual L298N drivers on the ESP32. Your first Wi-Fi rover.

## How it works

Driving commands from your phone travel over Wi-Fi to the ESP32, which translates forward, back, left, and right into signals for two L298N drivers — one per side of the chassis. Differential drive does the steering: spin one side faster and the car turns. Your first teleoperated rover.

## What you'll learn

- Differential drive kinematics
- Dual H-bridge control
- Wireless teleoperation
- Robot chassis integration
