This article is the first one in a series of articles (hosted @ hackaday.com) that aims to make you comfortable programming the Atmel AVR microcontrollers. It is a tutorial written for people that has never touched a microcontroller before. This first article discuss what a microcontroller is, how it works and shows the pinout of an example mcu (ATmega168). It also discuss about the tools needed, like the compiler and the programming software AVRdude etc. On the next article they will discuss about the hardware needed to programm a AVR microcontroller.

This instructable explains how to interface a 4×4 keypad over an I2C bus. I2C is a 2 wire bidirectional bus to which addressable devices can be connected. This will help to interface a keypad using only a few IO pins. It uses I2C remote I/O expander chips, a 4×4 keypad and a 7 segment display as output device.

This instructable shows how to build your own rainbow LED strip based on PICAXE-08M microcontroller. The light strip consists of a flexible copper tape with very bright surface mount RGB LED’s and each pair of LED’s is controlled by an HL 1606. The instructable user “johncohn” has reverse engineered HL 1606 to find out the signaling required to drive the strips. The signal required was a SPI – Serial Peripheral Interface. Check the details on the link below. [via]
