With the Mouse library, an Arduino Leonardo, Micro, or Due can manipulate the onscreen cursor of a computer. This specific instance involves the use of five pushbuttons to control the movement of the cursor on the screen. Four buttons control direction (up, down, left, right) and one activates a left mouse click. Cursor movement on […]

There is an episode of Ren and Stimpy with a big red “history eraser’ button that must not be pressed. Of course, who can resist the temptation of pressing the unpressable button? The same goes for development boards. If there is a button on there, you want to read it in your code, right? The Raspberry Pi
BUTTON, BUTTON, WHO’S GOT THE (PICO) BUTTON? Continue Reading
Pushbuttons or switches connect two points in a circuit when you press them. This example turns on the built-in LED on pin 13 when you press the button. image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires to the Arduino board. The first two, red and black, connect to the

In this instructable we will learn how to use 6 buttons to control the color of an RGB LED with the use of an Arduino Micro Controller. This is a fun and easy little project that should take you no more then 20 minutes to finish. Step 1: Connecting an RGB LED Before we connect

Once you’ve got a pushbutton working, you often want to do some action based on how many times the button is pushed. To do this, you need to know when the button changes state from off to on, and count how many times this change of state happens. This is called state change detection or edge detection. Circuit image developed
Button State Change Detection using Arduino Continue Reading
I made the original Instructible that this is based on over a year ago (You can see it here to see some of the theory around how this works:http://www.instructables.com/id/How-to-access-5-buttons-through-1-Arduino-input ). To make a long story short, I moved to a different country a few weeks after that and have not played with any electronics since.

Chachka is born! Chachka is an Adafruit Trinket CLONE built from the ATtiny85 microcontroller. Because it is a current Adafruit product, it has a training guide and its own support forum and lots of sample code. All of this means that like an Uno clone, the Chachka will be well supported with firmware and libraries and

Hello Everyone. This is my very first Instructable so please go easy on me. This was more or less a test project to see if my new arduino board worked. Any friendly advice will be greatly appreciated so my future posts can be even better. I am going to show you how to create the
Super Amazing Button using Arduino Continue Reading
THE SETUP For an interface I thought 3 LEDs would be simple enough: Blue for everything is fine (as blue LEDs are cooler than green ones); red for something is wrong; and yellow for the modem and router are being restarted. I added a button to do the actual restarting as I wanted it to

What’s simpler and dumber than a button, you ask… I say: behind a button, unexpected things can hide. And within a program that does various things, handling a button can be tricky. The nice thing is that interesting functions can be built with a simple dumb button. This tutorial will address these aspects: wiring and
