Re: Gyro Sensors
once a second would not be fast enough - the gyros have a bandwidth of 40 Hz - which means it can change values 40 times a second
so if you only read it once a second, you are only seeing 1 out of 40 possible outputs that it is creating each second.
If you want to integrate it to get compass heading, add the value to a integer variable in every pass (loop) of the SW - and make sure you subtract out the zero value (512 if you read it with a 10bit ADC - but you might need to see what the actual 'zero' value is by testing it on your bot).
