The 74HC595 is an easy and inexpensive (at about 60 cents apiece) way to increase the number of digital out pins on your Arduino. In this tutorial I’ll show you how to drive up to 16 LEDs with one 74HC595 using a technique called multiplexing. In the end, all 16 LEDs will require only three

In this project, we will go over how to build an arduino LED flasher circuit. We will use a standard arduino board, doesn’t matter which, and connect it so that it flashes an LED a certain amounts of times on and off repeatedly to create an LED flasher circuit. An arduino is a self-contained microcontroller.

Update: New interface – look at the last step. Credits: Arduino sensing done by DZL, Processing sketch and Instructable done by Mads Hobye. Disney Research lab designed a novel way to detect touch. You can see a video of their demo here: I had the honor to meet them at CHI2012 in Texas and I discussed with them

The DIY industry is booming, despite the desperate blackmailing of society by finance capitalists. Companies like Adafruit and Makerbot are grossing well over a million dollars a year, and Evil Mad Science Laboratories just recently dedicated themselves to running a full-time kit business. Making kits is fun, but starting a business can be scary. If

Step 1: What You’ll need A linux web-server with PHP, an arduino, a relay and some other components. Step 2: Upload your code to the arduino Upload the following code to your arduino: void setup(){ Serial.begin(9600); } void loop() { if (Serial.available() > 0) { char inByte = Serial.read(); if(inByte == ‘1’){ digitalWrite(13,HIGH); } else if(inByte == ‘0’){

I have an Arduino Uno connected to two IR transmitters and respective receivers. Basically, when one of the receivers detects a beam break, I have a strand of LEDs display a pattern. This all works in principle, but the problem is that when the IR transmitters and receivers are connected to the Arduino, the LEDs

I am twenty years old. I picked up my arduino for the first time this Christmas, and I’ve been keeping busy on my arduino applications so that I can bring you this instructable. I hope that it helps!!! The purpose of this project was to build a stepping stone from remote controlled flight to completely

In our previous two tutorials (see here and here), we created a Simon-type game using the Arduino, a hardware platform for simple, and not so simple, electronics projects. We placed three buttons and three LEDs on to something called a breadboard, and wrote a small program that would send a random sequence to the LEDs,

This is a simple solar tracker which automatically orients itself towards the sun or any bright source of light like the sun .If you place solar panels on this robot it can increase their productivity by 90 to 95 %. At first creating a solar tracking robot may sound complicated but it quite quickly becomes

In part 1 of our Arduino tutorial seres we covered the basics of how the Arduino works, and we’re going to use that knowledge in a hands-on project and see how this open-source hardware programming environment works when we’re actually trying to get something done with it. After this, you’ll have more than enough information
