Wireless Accelerometer Controlled rgb-LED’s using atmega168 microcontroller

MEMS (Micro-Electro-Mechanical Systems) Accelerometers are in widespread use as tilt-sensors in mobile phones and cameras. Simple accelerometers are available both as ic-chip’s and cheap development pcb-boards. Wireless chips are also affordable and available in assembled circuits, with matched antenna-network and decoupling-caps onboard. Hook both wireless board and accelerometer up to a microcontroller via serial interface

How to program a AVR (arduino) with another arduino using attiny2313 microcontroller

* 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 that you want to burn
