Have you ever wanted to control a Unity racing game using a real physical steering wheel? For many enthusiasts, standard keyboard controls lack the tactile precision and immersion that a physical wheel provides. So, in this project, we are going to build a simple Arduino steering wheel controller using a potentiometer and connect it to
The SONOFF DUALR3 is a versatile dual-channel smart switch that can turn two separate electrical loads into Wi-Fi-controlled devices. Instead of using a traditional wall switch alone, you can control your lights from the eWeLink app, create schedules and scenes, and connect the device to Amazon Alexa for voice control. We’re gonna learn how to
Introduction Infrared (IR) remote controls are everywhere—TV remotes, air conditioners, stereo systems. But did you know you can easily use them with your Arduino projects? With just a simple IR receiver module and a free library, you can turn an old TV remote into a wireless controller for robots, lights, or any other project you
The L293D motor driver IC is one of the most popular choices for controlling DC motors with Arduino. If you’ve used the L298N before, think of the L293D as its more compact, budget-friendly cousin—perfect for smaller projects where space and cost matter. In this guide, I’ll show you everything you need to know: what the
The L298N Motor Driver Module is one of the most popular motor drivers used in Arduino projects. It allows an Arduino to control the speed and direction of two DC motors independently, making it ideal for robotics, RC vehicles, conveyor systems, automated doors, and many other DIY electronics projects. So, we will learn everything you
Imagine a smart doorbell that works even when your internet goes down. No cloud dependencies, no Wi-Fi outages—just two ESP boards talking directly to each other, instantly. That’s exactly what we’re going to build today using ESP-NOW, Espressif’s incredibly efficient wireless protocol. Here’s what our smart doorbell system will do: Let’s get building! What You’ll
