With this ‘Test Fixture’ and provided software you can test virtually any MCU with as little as 4 digital I/O lines (even only 2 is possible, all be it tricky) for project suitability and performance. When I start a new project I don’t like hooking up a lot of wires before making any progress on

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

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

I came across Plama2002’s “Emergency Party Button” build a while back and wanted something similar for my bar. I also had an old USAF B-8 stick grip from an A-10A that I picked up in my previous life. I figured instead of just being a conversation piece, I could put it to good use as

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

Using this method, I’ll show you how you can access 5 (or even more) inputs through 1 Arduino pin. These buttons will only be read correctly if only one is pushed at any time though. As we go through it I’ll explain whatever background info you need to know, so as long as you can
