The Robotics Back-End

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

In this tutorial I will show you how to setup and use an IR (InfraRed) remote controller with Arduino. You will learn how to map each button of the controller to a specific action, so you can make your Arduino programs more dynamic. After reading this post you will be able to fully integrate any … Read more

In this tutorial I will show you how to make the Arduino pulseIn() function non blocking, using interrupts. Actually what we’ll try to do is to reproduce the behavior of pulseIn() without using it. I will not explain what is pulseIn() and how it works here, for that please check this pulseIn() tutorial first. The … Read more

The Arduino pulseIn() function may be quite hard to grasp at first. However, this function can be very useful to be able to read data from certain sensors. In this tutorial I will explain what is a pulse, how the pulseIn() function works, and how to use it in your own programs. >> Watch this … Read more
