I’m currently helping a couple of engineering students finish a senior project that didn’t get finished last year. Long story… Anyway, it’s a bicycle brake tester being built for Paul Components. The mechanical design is great, but they had trouble with the electronics. Part of those cinvolved writing numbers to a pair of Sparkfun 7-segment displays. […]

An old rotary phone can be used for a number of purposes in your Arduino projects – use it as a novel input device, or use the Arduino to interface a rotary phone to your computer. This is a very basic guide describing how to interface the dial to an Arduino, and get the number

Adding an LCD display to Arduino projects can add real value but the cost of doing so can be significant. Not a financial cost – you can pick up 16 (characters) x 2 (rows) LCD for as little as £3.50. The cost is the pin count it can take to drive them. Using the built-in

This example shows you how to monitor the state of a switch by establishing serial communication between your Arduino and your computer over USB. Hardware Required Arduino Board A momentary switch, button, or toggle switch 10k ohm resistor breadboard hook-up wire Circuit image developed using Fritzing. For more circuit examples, see the Fritzing project page Connect three wires

When the button is pressed in this example, a text string is sent to the computer as keyboard input. The string reports the number of times the button has been pressed. Once you have the Leonardo programmed and wired up, open up your favourite text editor to see the results. NB: When you use the

Arduino isn’t limited to taking input from sensors: you can even connect up a full-size PS/2 keyboard just as if it were a “real” computer and type away! Connecting a keyboard to an Arduino may sound a bit odd (after all, it’s just a little microcontroller) but keep in mind that an Arduino actually has

The Arduino Wireless shield allows your Arduino board to communicate wirelessly using Zigbee. This documentation describes the use of the shield with the XBee 802.15.4 module (sometimes called “Series 1” to distinguish them from the Series 2 modules, although “Series 1” doesn’t appear in the official name or product description). A Simple Example You should be able

In a couple of weeks, some students will visit my lab (Craft Tech Lab) to learn more about wearable technologies. I wanted to build a quick and simple application of a sensor and vibration motors for them to play around with and rough up. While this project could be made into a wearable mask, due

Overview: This instructable will construct a series of custom sensor modules and an Arduino shield. Such modules are available from many different sources, but fans of the Instructables website would probably find satisfaction in making their own. Each module will be a set size of 1.5cm by 2.5cm and employ a three pin connector of
