So, what exactly is this about?
Imagine: You are working on a project. You want to program in the Arduino language because of the simplicy. But you don’t want to use a 28 pin monster. Or you need peripherals like CAN or similar what the normal Arduino supported MCUs don’t have. So, what to do? Where are two alternatives:
1. Just don’t use the Arduino language and use things like bits and ports what you can’t understand.
2. Or continue reading this!

So, this instructable is going to show how to use the core files available from avr-developers.com. I’m also going to show you how to program the different MCUs and how to connect them to do so. At the end I’m going to give some ideas on what you can to with your new knowledge earned from this.

AVR

Microcontrollers are, without a doubt, amazing little things. They are versatile, powerful, and extremely tiny. Unfortunately, the latter trait is also shared by both my wallet and my programming skills. My understanding of C is poor, and I can hardly afford to buy something like an Arduino or a decent ISP. And in any case, the Arduino would be overkill for many of my projects, which only need simple IC’s.

But as many of you know, DIY always finds a way. This tutorial is meant for those among us with no budgets or programming experience who want to start using these little machines. It is not based around the ATmega328 (the Arduino Uno chip), but rather the Attiny line of chips (the Atiny85 and Attiny2313, to be specific). The total cost of this project can go as lower than $15 if you know where to buy from, and you can still use the original Arduino IDE and language to program your projects in the end. Keep in mind that you will need some soldering skills to get this project done.

Here is a very nice build of a LED heart that creates incredible animations. Check it out.

Today we present the perfect Valentine gadget: just shake it and it will turn on and crate incredible light animations. That will be cool for sure!

We know that, as it’s Valentine’s Day, looking at the device described in this post you’ll be inclined to think that this is the usual heart-shaped Valentine gadget: in reality this is something much cooler as it’s capable to create beautiful and complex light games. Is based on the smallest microcontroller manufactured by Atmel: the ATtiny85.

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.

@wiki.efihacks.com :

We wrote this whole page to try to make buyers of USBasp programmer clones aware of what’s possibly out there for sale and the conclusion we came to about the units we bought, after quite some investigative work IT SIMPLY DOES NOT REALLY WORK !!!

We tried to read the flash content, and the blue led flashes, but that’s about it … it does not work :(

BO.Duino is an Arduino compatible board based on ATmega328 ATMEL’s mcu. This board features many peripherals usually externally connected on a breadboard or prototyping board such as sensors, SD card etc. Peripherals included are:

- A real-time clock
- AT24 series external memory chip
- MicroSD card adaptor (SPI)
- RGB LED
- A potentiometer on analog input
- Connector for DS18b20 or DHt11 series sensors

Atmel’s Core-A5-based MPU handles displays up to 2048 × 2048

Atmel’s Core-A5-based MPU handles displays up to 2048 × 2048

By Jim Harrison:

The human-machine interface, once simply known as an “operator panel” or “terminal”, is changing rapidly, due to the graphical, visual way operators now interact with an industrial machine or process. At one time, designers of these systems could get by with a three-line segmented LCD display. Today, LCD interfaces are quickly replacing traditional LED and segment LCD displays as designers take advantage of the aesthetic, flexibility, and cost benefits they provide.

Analog-to-digital-conversion (ADC) is required in Embedded Systems to deal with various analog world parameters such as current, pressure, motion, temperature, etc. An ADC is an electronic system or a module that has analog input, reference voltage input and digital outputs. The ADC convert the analog input signal to a digital output value that represents the size of the analog input comparing to the reference voltage. It basically samples the input analog voltage and produces an output digital code for each sample taken. This application note from Atmel describes the fundamental concepts of ADC and the associated parameters that determine the performance and accuracy of the ADC’s output.
