These are step by step instructions for assembling the 8×8 LED Board kit from moderndevice.com. I had never played with LED displays before using this kit. I suggest reading through all the assembly steps BEFORE starting to solder because assembly order DOES matter with this kit. Overall, this is a very simple assembly. It does […]

The project This project follows on from the excellent work by ScotSEA and his Arduino reset program (see http://www.instructables.com/id/CatGenie-Resetting-a-SaniSolution-Cartridge/ ). I had never taken my Catgenie apart as Scott did, but had built a small contact board instead. I had previous updated Scott’s program to so that it output some debugging output to the computer

Although it is great controlling the robot arm with computer or mobile phone, I think using joystick is also cool, so I’ve bought a joystick shield and make a new project. This joystick shield is compatible with Arduino. It also support Nokia 5110 LCD module, nRF24L01 wireless module and Bluetooth module. It should be fun

Beat Sync is a single frequency audio spectrum volume meter. It can isolate around a certain frequency ( I choose the bass ) and display it on a creative 8 segment LED bar graph. This is meant to be quite simple, yet allowing room for more difficult upgrades. It is built around the Arduino Open

Good day fellow enthusiast! Here is one of my latest and simplest shield designs for an arduino board. The thing here is, sometimes we have a hard time checking out which I/O pins are LOW or HIGH, especially when we are dealing with LED, motors, etc. Now, here is one of the solutions that you

My brother posted a video about this on facebook almost a year ago. Some old floppy drives playing Bach’s masterpiece Toccata & Fugue and it got me really interested. So I read about it when the author posted a how-to on his blog and did a couple of tweaking using SammyIAm’s Musical Floppy program when the project gained a

The Siemens DLO7135 Dot matrix LED is one amazing piece of optoelectronics. It’s billed as a 5×7 Dot Matrix Intelligent Display (r) with Memory/Decoder/Driver. Along with that memory, it’s got a 96-character ASCII display set with upper and lower case characters, a built-in character generator and multiplexer, four levels of light intensity, and it all

Can a microcontroller control its own power? Well nearly! An ATX power supply, either new or from an old PC, is a great way to power Arduino and other microcontroller projects. That is covered in several ‘ibles such as this one. However, because of some of the special features of an ATX, we can use

How to use an Arduino to read the signal from a set of digital callipers and send the reading over USB. Why? This might be useful for accurate position sensing in home made / hacked computer aided manufacture systems. Adds USB functionality to your callipers. A great reference on reading digital callipers can be found

Build a unique personalised gift that’s cool and reflects the character of the recipient. What’s different about this Word Clock is that it is small enough to sit on a bedside desk, displays the recipients name and has personalised messages that appear at different times ie. Happy Birthday, Carpe Diem, Good Morning or whatever you
