Wireless Accelerometer Controlled rgb-LED’s using atmega168 microcontroller

Leave a Comment / Using Atmega /

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 […]
