This Instructable will teach you how to create magnetic robots that traverse vertical surfaces. These robots can move on any metallic walls, including elevators, whiteboards, refrigerators or metal doors. The robots are outfitted with several light sensors, allowing them to respond to simple user interactions. My implementation supports 3 robot ‘personalities’, which can be changed […]

LPG sensor using Arduino with alarm and cutoff. A simple LPG sensor using Arduino is shown in this article. This circuit indicates the amount of LPG in the air. The circuit  sounds an alarm and trips a relay  when the concentration is above a predetermined level. MQ2 is the gas sensor used in this project. […]

UPDATE 1: I HAVE ADDED THE CODE FOR CONWAY’S GAME OF LIFE UPDATE 2: NOW YOU CAN SAVE SOME ARDUINO PINS WITH THE HELP OF 1 SHIFT REGISTER. In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and […]

In present times there are many types of Home Automation Systems which are available in the market. Most of these are simple Home Appliances Controlling Systems like DTMF controlled Home Appliances, GSM based Home Appliances Controlling, RF based Home Appliances Controlling. Here we are going to discuss about TV or DVD Remote Control LED Home […]

What better way to start experimenting with open source micro-controllers ( Arduino ) then by building your very own open source robot ( CC (SA -BY) )? What to do with your SERB? (here) – How to connect your SERB to the internet and drive it over a Skype video call. (here) – How to […]

This Instructable shows you how to build a simple, inexpensive breadboard for robotics experiments. It is a companion to Cheap, Easy Robotics for the Non-Programmer. Here we’ll learn how to build a Babuino robot to use for experiments with the Babuino/Blocos software environment. Using a breadboard like this makes it easy to experiment with robotic […]

Pyroelectric (“Passive”) InfraRed sensors: ”’What is a PIR sensor?”’ PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don’t wear out. For that reason they are commonly found in appliances and […]

Scott W Harden has built an updated version of his ECG circuit for tracking his heartbeat. The main goal of the update is to provide a hack for collecting heartbeat with minimal h/w cost and circuit complexity. As you can see from the project photo above, the heartbeat detector is based on photoplethysmogram. Scott nicely describes the basics […]

UPDATE: A portable version of the Talking Breathalyzer is here http://talkingbreathalyzer.com The LED strips are mounted on an outdoor trellace which functions as a lightning simulator, outdoor breathalyzer, graphic equalizer synced to music, and a few other effects with sound. Materials: 8 12v RGB Waterproof Flexible LED Strips 10ft long (usledsupply.com) – $800 8 RGB 4A/Ch Amps (usledsupply.com) – […]

Arduino Uno is an opensource physical computing platform based on ATmega328 microcontroller and provides a development environment for writing software for the board. It can be used for a variety of projects. EM-18 RFID reader is one of the commonly used RFID reader to read 125KHz tags. It features low cost, low power consumption, small form […]
