In this project, we will build a Wi-Fi-controlled car using NodeMCU, Blynk IoT, and an L298N motor driver. This project allows you to control the car using your smartphone via the Blynk app, providing a fun and interactive way to explore IoT, robotics, and home automation. We’ll guide you step-by-step through the process of assembling […]
