Or, an exercise in input and output multiplexing, and working with bits.  And a submission for the Arduino contest. This is an implementation of a tic tac toe game using a 3×3 array of bicoloured LEDs for a display, a simple resistive touchpad, and an Arduino to tie everything together. Parts and consumables One perf […]

In this tutorial, a temperature sensor (MCP9700 linear active thermistor IC) and LCD are connected to the Arduino. The Arduino reads the temperature from the MCP9700 on analog pin A0 and displays the temperature on the LCD. This video shows the circuit operating. When touched with a finger, the temperature sensor IC will measure an […]

I’ve seen a number of tutorials about how to build the platform for a 3-axis CNC milling machine.  I have not seen anyone tackle the tricky subject of the electronics. Here now is my attempt to do so. Step 1: Parts You’ll need: – an arduino. I chose duemilanova. (depends on the board you get) […]

This example shows how to simulate a simple closed-loop control algorithm in Simulink and how to run it on an Arduino Mega 2560 board. Contents Introduction Prerequisites Required Hardware Task 1 – Build the Vehicle Task 2 – Build the Motor Controller Task 3 – Simulate Open-Loop Control Model Task 4 – Run Open-Loop Control […]

Like many people, I often find myself unconsciously tapping my feet, whether it’s along to a song or out of some nervous habit. As fun as that is though, I’ve always felt as if something has been missing. If only I could trigger the sounds of say, a rabid pack of furious jungle beasts instead […]

This project uses relays to control a Firgelli Automations linear actuator without feedback. The relays are controlled by the MIDI Volume (Control Change number CC7) command which is read by the microcontroller and converted into one of the only 3 states of operation: 1) The Linear Actuator is stopped, 2) The Linear Actuator is extending, […]

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 […]
