While waiting for our Handy Board, we want to test the Polaroid sensor.
A few questions....
PULSE WIDTH? The Polaroid manual isn't real specific on the init signal
that fires the transducer. It wanst a Schmitt trigger pulse, but is
there an optimum trigger pulse width?
POWER SUPPLY? I've read that the intensity of the transmit pulse will
reset or whack out the board if power is shared.
- So how much oooomph do I need for transducer power, for say one or
two hours of use?
- Can the main power source handle the 68HC11 and propulsion motors
OK (noise/interference wise), or will a third power supply be better?
