For this tutorial, we’re going to be using a DHT11 temperature sensor. Temperature sensors are used for thermostats and many other recreational projects and we’re going to learn how to output the temperature and humidity values.

LCD screens can be useful for your Arduino projects and in this tutorial, we’re going to learn how to use one.

You can make many cool melodies with these buzzers and in this tutorial, I’m going to show you how.

Ir Sensor uses input from a controller to return a response. TVs, DVD players, etc uses IR sensors to receive input from a controller or TV remote to operate.

This is part 2 of this LED strip tutorial. Feel free to look at the previous one which is the solid color tutorial. We’re now going to dive into a slightly more challenging version of our LED program.

An Ultrasonic Sensor uses sonar to detect the distance of an object. In this tutorial, we’re going to learn how to program an ultrasonic sensor to receive distance values of objects. For this tutorial, we’re going to be using an HC-SRO4 ultrasonic sensor to get the distance value in inches of any object that is …

Servo motors are a type of motor that can only rotate from 0-180 degrees. This motor can be very useful such as making locks for doors or a switch.

LED strips are very cool for many aesthetic situations but programming them is way cooler. In this tutorial, we’re going to learn how to light them up.

In this tutorial, we’re going to learn how to use a button with Arduino.

Hello! Today we’re going to learn how to use a potentiometer with Arduino and get values from the Arduino.
