This instructable was inspired by my first AVR microcontroller project that I’ve been working on for some time now. I wanted to start learning more about the AVR microcontroller and see how much I could do with the minimum amount of hardware… no extra chips, simple components, etc… just my AVR and my code so […]

This instructables is usefull if: * you’ve got your arduino with atmega168 and you bought an atmega328 at you local electronics store. It doesn’t have an arduino bootloader * you want to make a project that doesn’t use arduino – just a regular AVR chip (like the USBTinyISP) – you have a clean attiny2313/attiny48 etc

Lets start off by saying that I am a noob to micro controllers like Arduino. After looking through instructables for a while I saw the things that arduino could do. That is when I realized that I had to get one and learn the whole process of programming. So having said that I will now

Intro: My Nikon DSLR has an infrared remote function (remote sold separately) that is really handy, but fairly limited in range. A while ago, I bought a TV-B-Gone Kit from it’s inventor Mitch Altman, and it can turn TV’s off from a great distance. I thought, “Hey, this thing is open source! I can hack

My last visit to the dentist convinced me that I should really brush my teeth at least two minutes. I decided to build a special toothbrush timer: it would detect when a brush is taken out, measure two minutes and notify when the time is up. I chose to use Atmega328p, a weight sensor, brass cups,

In this Instructable, I cover modding the store-bought Deluxe Identity Disc to an upgraded version with 64 leds, controlled by an AVR MCU. The upgraded version is costume-ready and would be an excellent addition to your Tron costume – it’ll also look great on your desk/dresser/etc. My 7 year old daughter watched Tron:Legacy with me

Ever wanted a robotic liquor server?I purchased a Lynxmotion robotic arm last year and an Arduino (deci) to play around with. I had it serial controlled with a joystick and it was a great way to start in robotics. More recently I wanted to take on another micro-controller related project for a university science fair.

This tutorial will show you how to build a jacket with turn signals that will let people know where you’re headed when you’re on your bike. We’ll use conductive thread and sewable electronics so your jacket will be soft and wearable and washable when you’re done. Enjoy! A version of this tutorial is also on

Shift registers are a very important part of digital logic, they act as glue in between the parallel and serial worlds. They reduce wire counts, pin use and even help take load off of your cpu by being able to store their data. They come in different sizes, with different models for different uses, and

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
