Recently I was working on a project that involved rotary encoder. I thought I’d share some thoughts on how rotary encoder can be interfaced and programmed. Actually it is easy to work with rotary encoders – interfacing is simple – only three wires are required to connect to microcontroller (two for signal (quadrature outputs) and one for …
Recently a family member had his furnace fail while he was away from his house for a long period of time in the winter. His pipes burst and caused quite the mess. This project describes a temperature sensor that broadcasts the temperature in his house to the pachube data logging website. This allows him to check on his house …
A friend of mine is a scientist who does experiments that are very sensitive to air temperature and humidity. The incubator room has a small ceramic heater but the heater’s thermostat was not nearly accurate enough, only able to maintain the temperature within 10-15 degrees. Commercial devices that log temperature and humidity can be quite …

The platter of a hard drive spins well over sixty times a second. If a narrow slot was cut into the platter to allow LEDs to shine through, we can achieve flicker fusion and trick the eye into seeing a stable image. This phenomenon is known as persistence of vision (POV). There are many examples of LEDs being used for POV, building …

This Instructable shows you how to build a four-gang outlet box in which each outlet is controlled via an Arduino (or any other TTL level signals). It differs from the other relay boxes in that it uses no circuit boards and has very few parts (one chip and 4 relays). Step 1: Assemble Materials/Review Plan Tools …
Hi, First of all, my English is not perfect =) I’ve seen many projects with Arduino that describes how to control 2 servo’s with a joystick or use a lcd screen. All of the projects that i have seen are all seperate things. So i decided to make a short Instructable of these things combined. …
Ever wanted an LED tree? Well now you can have your LED tree and eat it too (no, wait, you probably shouldn’t).. Step 1: Gather the parts You will need: 1x ATtiny85 10x male header pins Solid core wire, 2 colors A bunch of LEDs 1x Arduino Uno to program the ATtiny Step 2: Program …
If you have looked at my 5 LED ATtiny85 POV display, we programmed the ATtiny with the Arduino. (If you haven’t seen it, click here) We will be doing the same thing for this LED Dice project. The total parts cost for this project is about $5-$10. (Not including the Arduino board and the tools.) It …

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 …
Adding an LCD display to Arduino projects can add real value but the cost of doing so can be significant. Not a financial cost – you can pick up 16 (characters) x 2 (rows) LCD for as little as £3.50. The cost is the pin count it can take to drive them. Using the built-in …
