In this Arduino UNO tutorial, we are going to use a Light Dependent Resistor (LDR) to create a simple childrens bedroom nightlight which turns on automatically when it gets dark and turns off when it gets light. An LDR’s resistance changes depending upon the amount of light hitting the sensor. For the LDR we are

I’ve been on mission lately to design a handheld bluetooth game controller. I’ve made a prototype in the past but, it never was really usable as a gaming device. Although the concept worked well the form factor was not quite there. Well after a few months of tinkering and several designs I finally have one! The design

I bought a small aquarium (54l) as an impulse buy and I needed some lights for it, so naturally I wanted to use LEDs. I also needed a timer for the lights. I also wanted the lights to fade in and out when they were going on or off as a cool effect. I ordered

This is a relatively simple clock to build, in terms of the hardware required and in terms of hooking up all the wires. The complexity lies in the software, which I’ve conveniently included as part of this instructable 🙂 This instructable illustrates a few things: * Keeping relatively accurate time on an Arduino without using

I spent the better part of the day on Saturday doing some more basic research into connecting an Arduino and LCD for this ongoing project. For the most part, it’s pretty basic and following the wiring diagrams and tutorials online is fine. I ran into a problem with getting text on two lines, which I’ll

The Arduino Yún is a WLAN capable development board featuring an ATMega microcontroller, as well as a separate chip running a small Linux distribution, making it a perfect candidate for home automation projects like in the picture below! This basic tutorial will show you how to communicate wirelessly between your Arduino Yún and an Android

One day while exploring the bric-a-brac at the markets, I stumbled across an old, Bakelite slave dial from the 1950’s. Slave Dials are clock movements without the actual time keeping circuit. All they contain is the mechanism to drive the hour and minute hands, which can be advanced by an electric pulse. This pulse is

In this project we make electronic dice. Updated 18/03/2013 In this article you can learn how to make an electronic die (die is the singular of dice), using an ATmega328 with Arduino bootloader and a few inexpensive components. The reason for doing this is to introduce another object that you can build, learn from and be proud

I’ve been slowly working on this project for the past month or so. I finally have some time to share and post-up what I’m working on. I know there are commercial products available, but then what’s the fun in that! What I want is a Fully Automated LED Primary Lighting System which can control separate
