 | | LEGO Rotation Sensor —Rob Murray
| | | | This is a follow up to my original question about the rotation sensor. When we hooked the sensor up to the oscilloscpe and the Handy Board, we could see the voltage transitions on the scope. Now, we truned the sensor very slow (about 2 ticks per (...) (24 years ago, 27-Feb-01, to lugnet.robotics.handyboard)

| | | | | Rob, a few Q's: 1. Can you verify that +9v is being applied to the sensor by transistor Q2. Measure the voltage at the collector, you should see a pulsed waveform (rectangular wave) with +9v on's and 0v off's. (Refer to (URL) What is the (...)
