These Days im building a Balancing Robot so here are step wise how to interface a arduino to Accelerometer and Gyro
Things ive used
1. ATmega8 Arduino ( ARP 1.0u)
2. DIY Proto Shield
3. 3.3V Zener + 330 Ohm for 3.3V supply
4. Triple Axis Accelerometer Breakout – MMA7260 ( @Sparkfun )
5. Gyro Breakout Board – LY530AL – 300°/s ( @Sparkfun )
The Gyro and Accelerometer were bought from Feemo India , as i found them the cheapest retailers
