In this tutorial you will build a dice that is shaken by holding the button in and thrown by releasing the button. The shake, throw and number thrown are animated and displayed on a seven segment display. A 74HC595 IC is used to interface the 7-segment display to the Arduino, using only 3 Arduino digital […]

This foot pedal plugs into the Arduino case which plugs into your PC via microUSB cable. Arduino microcontrollers can easily be used to power fun projects like robots and even sending tweets to Twitter but they’re versatile enough to turn up in the strangest of places – like under your feet. We had a question

I have a device which provides a USB port. If I attach it to a Windows PC it is recognized as a “CP2103 USB to UART Bridge Controller”. According to the device documentation, it should communicate in serial format at 38400bps.I have to talk to this device with a atmega microcontroller. Since the USB pinout
Introduction This is the second article in a three part series I am writing on the Arduino hardware platform. This article focuses on wiring an Arduino to a character LCD and a graphic LCD, and includes static and animated demos to show off the capabilities of each display. Character and Graphic LCDs After I initially

Everyone has used a magnetic card reader, I believe. I mean, who carries cash these days? They’re not difficult to get your hands on, either, and during a trip to my favorite local electronics shop, I found a bin full of these guys. So….of course, I picked one up and brought it home to see
Turn your Arduino into a Magnetic Card Reader! Continue Reading
This tutorial is for all those people who have an Arduino and want to use there Wii nunchuck as an input device, but don’t really feel like cutting open the cord and ruining the nunchuck FOREVER!!!!!!!!well you’ve come to the right place! Step 1: Supplies These are the supplies you will need most can be

This post is about an arduino-based intervalometer I built for my camera, a Fuji S9600 dSLR. I decided to go for a very simple interface: a rotary switch in the middle of a plastic box which would allow me to select 12 pre-defined intervals. I went for a switch and not a potentiometer because I

This Instructable explains how to send an SMS from an Arduino using the Internet. There are many ways to approach this and I will explain one of the different methods used to accomplish this task. Some major points needed for my project: I have a standard Ethernet shield, and ENC28J60 Ethernet module, and I needed
Send SMS from Arduino over the Internet using ENC28J60 and Thingspeak Continue Reading
I’ve had an Arduino Duemilanove now for a couple of weeks. If you’re not familiar with the Arduino, it is “an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software”. It has a small microcontroller, a USB port to connect to your computer for programming, a power socket for providing power when the
