Tutorial: How to control a servo motor (SG90) with the Arduino Uno
Typically, servo motors are a combination of four things: a conventional DC motor, a set of gearings, a potentiometer, and a control circuit. Among...
Tutorial: How to drive the 28BYJ-48 stepper motor with a ULN2003A driver board and an Arduino Uno
A stepper motor divides a full rotation in multiple steps. As a result, a stepper motor can be driven much more precisely than a...
Tutorial: How to use the HC-SR505 PIR sensor with the Arduino
PIR (Pyroelectric InfraRed) sensors measure infrared (IR) light that is radiating from objects in the detection area. The HC-SR505 is such a sensor. It very...
How to control an LED pixel strip (WS2812B) with an Arduino and the FastLED library
LED pixel strips are strips which have small LED modules mounted on it. One of these LED modules is the WS2812B which features a cascading...
How to control a DC motor with the Arduino Uno and the L298N Dual Motor Controller
In order to control a DC motor with the Arduino Uno, a motor controller module is required. Such module is needed, for various reasons: For...
