|
|
Hi, I am working on a robot with the HandyBoard. I am thinking about using the Sharp GP2D12-Sensor because the other IR reflective sensors I use won't work under sunlight. I read the spec. sheet of GP2D02 and GP2D05, both of them mention that they (...) (24 years ago, 1-Jul-00, to lugnet.robotics.handyboard)

I also tried all sorts of capacitors, etc. in an attempt at solving this problem. While the capacitors helped to minimize the length of time before the motors calmed down, there was always a short period of motor craziness that never went away. I (...)

The counter increases each 0.5ns (pink book). Sound (...) (24 years ago, 30-Jun-00, to lugnet.robotics.handyboard)

Greetings all, Has anyone managed to work out some code which checks the overflow bit for the counter used in the polaroid sonar code? At the moment mine distance readings seem to be maxing out around 1.5m or so, and I'm not sure if it's the timer (...) (24 years ago, 30-Jun-00, to lugnet.robotics.handyboard)
