Reset Sensor value? #57

Closed maxnoe closed 9 years ago

maxnoe commented 9 years ago

Is it possible to reset (or set) a sensor value?

I would like to null the gyro at program start and maybe several times in the program.

It depends on the sensor. For example, the LEGO EV3 Gyro sensor can be reset by momentarily changing to a different mode and then changing back to the desired mode. Most of the other gyro sensors out there don't have a reset function. You just have to maintain an offset variable in your program and use that to "zero" the sensor value.

Ah, ok thanks. I was talking about the LEGO Sensor.I thought i could avoid keeping track of the sensor value at certain positions.
