tilt sensor

Tilt sensor/switch for an RC rideable vehicle

The Project:  I am building a 1/4 scale radio controlled Ford F150 pickup.  The body style was chosen for me when I was given a free 1/4 scale fiberglass body.  The drive-power was originally going to be a small 2-stroke engine, but I was also given a free Pride Mobility Scooter/wheelchair that came without a controller or batteries.  Speed and direction control will be in the form of a SyRen 1X50 from Dimension Engineering, which in turn will be controlled from a common RC transmitter and receiver.

Accelerometer as a Inclination (pitch) sensor

Hello everybody!

I'm an robotics hobbist an I'm planning to put some sensors and a microcontroller to a RC Car to log some status data.

First sensing will be reading pitch angle when RC car is running uphill and downhil using a 3-axis accelerometer. I've read some documentation on how to do this and a little bit confused, my question is:

How to convert accelerometer values to angles when RC Car is moving? I'm only interested in inclination angle, pitch.

 

Thanks in advance!

I bought some small tilt-sensors. basicly they where a small metal capsule with a ball inside. When tilted, the contact was switched on/off. I thought this was … Read more
