Arduino Push Button with Multiple LEDs [Tutorial]

In this Arduino tutorial you will learn how to work with a push button and multiple LEDs. We will first build the circuit, and then write some code for different applications, each time adding a bit more complexity. In this tutorial, in order to not bloat the instructions too much, I will not explain every … Read more

Arduino Potentiometer with Multiple LEDs [Tutorial]

In this Arduino tutorial you will learn how to control multiple LEDs with a potentiometer. I will not explain everything from scratch, so it’s better if you already know a bit about LEDs and potentiometer before reading the following. If you have some doubts, check out how to control one LED with a potentiometer. We … Read more

Arduino – Control LED Brightness With a Potentiometer

In this Arduino tutorial I will show you how to control an LED with a potentiometer, and more specifically, how to control the LED brightness. You will learn how to dynamically make the LED fade in/fade out when you turn the potentiometer knob. If you’re not familiar yet with the LED or the potentiometer, check … Read more

Arduino Potentiometer – Complete Tutorial

In this Arduino tutorial you will learn how to work with a potentiometer. We’ll start from scratch, building the circuit. Then you will write the Arduino code to interact with the potentiometer, so you can read some data. And finally you will learn how to make sense of the data you got from the potentiometer, … Read more

Arduino LED – Complete Tutorial

In this complete tutorial you will learn how to use an LED with Arduino. First, you will setup your circuit with an Arduino board and an LED, and then discover different ways to control the LED. I will use Arduino Uno for the examples but the instructions here apply to any Arduino board. If you … Read more
