Program Robots Like a Boss
In this Arduino tutorial you will learn how to control an RGB LED with a potentiometer. First using only digitalWrite(), to get an idea of what we’re doing, and then with a more complex computation and analogWrite(), so we can get any color we want. If you’re not familiar with how to use a potentiometer … Read more
In this Arduino tutorial, you will discover different examples of what you can do with an LED, a push button, and a potentiometer – using the 3 components at the same time. This tutorial is more of a practice/exercise on top of a series focused on Arduino and the various basic components you can control. … Read more
In this tutorial I will show you how to improve your Arduino code when using multiple LEDs, with the help of arrays, and also with functions to make those arrays more dynamic. When you get started with Arduino you usually do small projects, with for example one LED. After some time you add more components … Read more
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
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
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
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
This tutorial was written by Ron as a guest post – check out more of his work on the Visuino website. In this tutorial we will learn how to Display a temperature using a servo motor as a gauge and a DHT sensor connected to the Arduino board. Watch the Video! Step 1: What You … Read more
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
In this complete tutorial you will learn how to use a push button with Arduino, with different circuit configurations. You will also see how to use the push button for various applications, and take advantage of some of the Arduino capabilities, for example interrupts. I’m going to use an Arduino Uno board, but this tutorial … Read more
