Analog read produces a value of 0-1023, equating to 0v to 5v. "((long)sensorValue * 5000 / 1024)" is the voltage on the sensor's output in millivolts. There's a 500mv offset to subtract. The unit produces 133mv per amp of current, so ...

Arduino, Gyroscope and Processing: Hi guys, this is my first attempt to post a project here.This is an instructable on how to read a gyro sensor and plot the data using processing software at your desktop. I am using gyroscope model XV81-000 and an ardui
