In this project, we will go over how to connect a microphone to an arduino so that the arduino can detect whether there is sound in the environment or not. This circuit is only capable of detecting whether there is sound in the environment or not. It won’t be able to record the words that […]

Have you ever felt like the mail sound on your Mac just wasn’t enough? Simple sounds and alerts just don’t cut it for you? You want something more apparent and rewarding? If so, this is the Instructable you’ve been looking for. In this Instructable, I’ll show you how to hook up your Arduino to your
Create an Applescript/Arduino Alert flag. using arduino Continue Reading
In this project, we will demonstrate how to build temperature sensor circuit using a LM35 sensor. As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay thi temperature to us back in degrees celsius. The IC we will use to measure the temperature is the LM35 IC. We will

Including voltage measurement via AC-AC voltage adapter and current measurement via a CT sensor. This guide details how to build a simple electricity energy monitor on that can be used to measure how much electrical energy you use in your home. It measures voltage with an AC to AC power adapter and current with a
Soldering SMD components isn’t as hard as you might think. In fact it’s easy. If you follow this instructables you’ll soon see just what great results you can obtain at home using just a hotplate. It’s not just being able to make small circuit boards that makes SMT soldering so good it’s also a nicer

Today we’ll expand Arduino’s digital resources thanks to an I2C bus equipped shield and we’ll allow the management of the board via a bluetooth connection RN-42 through an Android systems. All Arduino boards feature a number of digital I/Os. For the simplest projects, such resources are usually more than sufficient, but in those where they

I’ve reached the point where I need to think how I’m going to control the motor & linear actuator for my solar tracker. Things to consider – Must be able to go forwards and backwards – so that makes 4 channels, 2 for each motor. Must be able to provide enough power to drive the

In order to “visually” highlight the behavior of Arduino programs you must connect a device to the I/O pins, which gives you tangible signals. Normally, if you want to check if a program changes a level of an output pin, answering a command or executing a check routine, or event, you must check it by
A useful and simple IO Shield for Arduino Continue Reading
What is Teagueduino? Teagueduino is an open source electronic board and interface that allows you to realize creative ideas without soldering or knowing how to code, while teaching you the ropes of programming and embedded development (like Arduino). Teagueduino is designed to help you discover your inner techno-geek and embrace the awesomeness of making things

The DIY Cellphone is a working (albeit basic) cellphone that you can make yourself. It can make and receive phone calls and text messages, store names and phone numbers, display the time, and serve as an alarm clock. It connects to GSM networks (like AT&T and T-Mobile in the U.S.) using a regular (full-size) SIM card. It
