Electronics
Electronics is a fun hobby that you no longer need to be a rocket scientist to enjoy. The availability of low-cost modules and test equipment has made this a great hobby for people of all ages.
Arduino
Arduinos are inexpensive microcontrollers that come in all sizes! With an assortment of Analog and Digital inputs and outputs combined with a simple programming language, they are the ideal choice for all kinds of projects.
ESP32
The ESP32 is an inexpensive yet super-powerful 32-bit microcontroller that is loaded with advanced features. With built-in WiFi and Bluetooth BLE, the ESP32 can be the brains of your next Sensor, Robotics, or IoT project!
Raspberry Pi
The Raspberry Pi is a microcomputer with a micro price. But don’t be fooled by its size, it packs a powerful punch!. Media Center, Home Control, Robotics, or Desktop Replacement – you can do it all with the Raspberry Pi.

Controlling DC Motors with the L298N Dual H-Bridge and an Arduino
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! -
Stepper Motors with Arduino – Getting Started with Stepper Motors
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. -
Using Inexpensive 433MHz Transmit and Receive Modules with Arduino
Those inexpensive RF transmitter and receiver modules that you can get on eBay and Amazon are perfect when you need a low-cost method of sending one-way data between two Arduinos. In this article you’ll learn how these modules work and how to use them in your next Arduino project. -
Wireless Joystick for Arduino Robot Car with nRF24L01+
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!
