anool @ wyolum.com builds a pulse lamp controller for the parking light of his KTM bike. He writes:

My brother is a Mechanical Engineer who loves his KTM Duke 200 bike. He asked me to build this circuit : http://sunbizhosting.co.uk/~spiral/blog/?p=227 for a ‘heartbeat’ lamp controller for the parking light. A Neutral Detect (ND) signal controls the lamp pulsing. When ND is HIGH, the Lamp is fully lit. When ND goes LOW, the lamp starts pulsing.

I’m not familiar with PIC microcontrollers, and didn’t want to dabble in “C” code. I’d be comfortable with an Arduino, but even the smallest ATMega seemed too big (and overkill) for this simple requirement. How about an ATTiny ? A bit of Googling, and I found this excellent resource for running the Arduino environment on the ATTiny : http://hlt.media.mit.edu/?p=1695

If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. In this video, Matt Richardson shows you how, based on a tutorial from MIT Media Lab’s High-Low Tech Group. The best part is you can use the same Arduino code and development environment that you’re already used to.

The 8-Pin Programming Shield allows you to program ATtiny series chips using the Arduino itself as the programmer. In other words, you plug this into your Arduino and then you can easily program 8-pin chips. These small microcontrollers can then be incorporated into any project that you want. Follows are instructions for assembling your own 8-Piin Programming Shield.

In this article you will learn how to programm an ATtiny mcu using Arduino IDE.

Follows are directions for programming the ATtiny microcontrollers using the Arduino IDE. In plain English, this is how to program 8-pin Atmel chips as you would normally an Arduino. This is cool because the ATtiny is tiny, and – well – this allows you to make tiny things that don’t need a big ol’ microcontroller.

Niek designed this BareDuino micro, that is available at github:

For some Arduino projects, you don’t actually need that many IO pins. That’s exactly the case when I tried to build a simple RGB throwie that would cycle through colours. I was looking for a cheaper alternative to the Arduino UNO’s ATmega328P when I stumbled across this post by MIT’s High-Low Tech lab. They developed a library for programming the 8-pins ATtiny45/85 from the Arduino IDE. It’s a very smart solution to use permanently in some low pin-usage projects, but you still need to hook up individual wires from your programmer to the ATtiny to be able to program it. That’s when I came up with the idea of the BareDuino Micro.

For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude).

USBTiny-MkII SLIM programmer (AVRISP-MKII clone) supports all Attiny, Atmega, and Xmega µcontrollers. It has three programming interfaces: ISP, PDI, and TPI. It works with AvrStudio or AvrDude. Small convenient board, contains double direction voltage translator for all interfaces and working from 1,2V, jumper for target chip voltage selection 5V or 3,3V (LDO stabilizer), and status LEDs. The heart of the device is a AT90USB162 controller with hardware USB, so it can provide fast programming speeds.

Atmel semiconductors have earned a big popularity all over the world. That´s why in our portfolio can be found a lot of standard stock types and upon request, we´re able to supply you with virtually any Atmel component.

AAVR, ATmega, ARM, ATtiny, 89C2051, 89S… these are the terms familiar to perhaps every developer of applications with microcontrollers. Atmel products have gained their reputation also thanks to a fact, that in their wide portfolio can be found microcontrollers for a wide spectrum of applications – from simple ones to relatively sophisticated powerful applications. Besides standard stock types, also many other types, can be found in our webshop, which we´re usually able to provide you within few days. Who ever tried to use any – even relatively simple and cheap microcontroller, knows, that such a component is able to add an unbelievable functionality and flexibility to a target device, most often inimplementable or only inefficiently implementable from discrete components. Atmel also provides a vast support in a form of application notes, development SW and HW, or examples in a source code – all are free to download at Atmel website.

We’ve added a new sheet that covers most of the chips that were missing in the Atmel ATmega and ATTiny families, specifically the ones that come in only SMD packages. The chips included are ATtiny 4/5/9/10/20/40/24a/44/84a/43u/87 and 167. We’ve also added the ATmega8/48/88/268/328 in TQFP package which has a different pinout than the DIP package covered in the original reference sheet.

If you spend any time playing with Arduinos, ATtinys or looking at AVR spec sheets, you soon encounter a bewildering smörgåsbord of acronyms for various communication protocols. With examples such as I2C, LIN, SPI, TWI, USI, etc., it can get pretty confusing. What do these terms mean? How do you choose the chip that meets your needs? How do you make use of these protocols?  This guide will take the mystery out of all these acronyms, and provide a brief overview of what they mean and how you use them in your projects.
