Adding ICSP header to your Arduino/AVR board using ISP10PIN microcontroller

So you may have been playing with Arduino’s, or rather, Hackduino’s. If you made your own Hackduino or similar project, you may be wondering how to add the ICSP header. Basically, using the ICSP header will allow you to use an external programmer to ‘upload’ software to your MCU (microcontroller unit). This will work for […]

Synchronizing Fireflies using Microcontroller ATtiny13

Have you ever asked yourself how do hundreds and thousands of fireflies are able to synchronize themselves? How does it work, that they are able to blink all together without having a kind of boss firefly? This instructable gives a solution and shows how this synchronization can be achieved.   I have always been fascinated

LED matrix using shift registers

This instructable is meant to be a more complete explanation than others available online. Notably, this will provide more hardware explanation than is available in the LED Marquee instructable by led555. Goals This instructable presents the concepts involved with shift registers and high side drivers. By illustrating these concepts with an 8×8 LED matrix I

Faraday For Fun: An Electronic Batteryless Dice using Microcontroller ATTiny13

There has been a lot of interest in muscle powered electronic devices, due in large part to the success of Perpetual Torch Perpetual Torch, also known as battery-less LED torch. The battery-less torch consists of a voltage generator to power the LEDs, an electronic circuit to condition and store the voltage produced by the voltage

Buggy – A Crafty Programmable LED Creature using Microcontroller Atmel Attiny44v

Buggy is a programmable LED craft project using a homemade, single-sided, PCB board, and a programmable AVR Attiny44v microcontroller. Buggy has two bi-colored LED eyes and can sense visible and IR light and emit sounds using a piezo speaker. Not counting the board, there is about $8 USD in parts per bug. I designed this
