Sept. 06:

Pete @ Techno-Stuff has just sent me another new sensor from Techno-Stuff. This time it’s a Accelleration / Tilt sensor. Instead of going into great detail on how it works, I will quote from his site:

The Accel Sensor lets your robot measure it’s acceleration. The sensor can also be used to measure tilt. This is a two channel device that lets you measure acceleration or tilt along two perpendicular axis. Acceleration is a change in speed. When you push the gas pedal of a car, and the car speeds up, this is acceleration. The Dual Acceleration/Tilt Sensor (Accel) measures acceleration by it’s effect on a small mass. The sensing mass is also affected by gravity. Because of this, the sensor can be used to measure gravity. Gravity is constant, and points straight down. Since the Accel sensor can measure gravity, you can use it as a tilt sensor. The sensor is most sensitive to tilt when it is mounted so the sensing channels are perpendicular to gravity. (the electrical connector is horizontal) When mounted this way, the light sensor value will be 50, indicating zero acceleration. The value will increase or decrease depending on the direction of tilt.

So, to put the sensor to the test, I thought what better way to do this than to use my NXT kit.
