Controlling DC Motors is an essential skill for constructing robots and other hobby projects. An easy way to control DC motors is to use an L298N H-Bridge, an inexpensive component that you can buy from several sources. Fear not if you’ve never heard of the L298N or if you don’t know what an H-Bridge is - in this article I’ll show you everything you need to know to start making things move with an Arduino. We’ll even construct a simple Robot Car that you can pilot using a Joystick.So let’s get our motors running and learn all about the L298N H-Bridge!

Today we will look at the amazing ESP32-CAM module from A-Thinker. This 10-dollar module features a 2MP camera, microSD card socket, WiFi, and Bluetooth.Unlike other ESP32 modules this one does not have a USB port, so you'll need to use an FTDI adapter to get it working.In this article I'll show you how to work with the ESP32-CAM and how to resolve common power and antenna issues.

Learn to use the popular nRF24L01 radio modules with an Arduino, using the RadioHead library. In this article we will conduct several experiments sending data between two Arduinos with the nRF24L01. We will then take what we have learned and build a wireless joystick controller for our robot car!

Stepper motors are used in a variety of devices ranging from 3D printers and CNC machines to Blu Ray drives, cameras and even analog clocks. In this article you’ll learn how steppers work, the difference between bipolar and unipolar stepper motors and how to control both of them with an Arduino.

A Bench Power Supply is an essential component for any serious electronics experimenter. But a good supply with multiple output voltages and a high current capability can set you back some serious cashIn this article we'll look at an alternative - using an old computer ATX power supply as a high-performance workbench power supply.It's a simple project that can give you a highly capable piece of equipment for next to nothing
