An Analog Feedback Servo Motor is a servo motor that has a connection to its internal feedback potentiometer. Thi sallows you to measure the precise position of the motor shaft in real-timeToday we will learn how to calibrate and use this motor, we'll even see how it can be used as an input device to memorize and repeat a sequence of movements.

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 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.

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.

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!
