Hi John, I am interested in your handyboard ! I'm curious, when you say your board only has one motor chip is that something you added on or does that mean it only has one of the four outputs for DC motors, that usually comes with the board. Or does (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)

(...) When I first got my HC11EVB I ran 12V straight into the E port (one of the pins), and was sure I ruined the chip. I called the tech support person at motorola, and he said 12V on a A/D port should be no problem. Sure enough it all still (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)

1. yes, you probably killed your analog 5. the analog inputs are very sensitive to over voltage. if your ran more than +5v directly into the input, you probably killed it. next time you're playing with funky voltages, put a 5K resistor in series (...)

Ummm, Hi all I'm looking for a circuit that will interface a photo transistor or a photo diode to a digital input. I tried a photocell in an analog port but it's too slow, I want to use a *visible* light pulse as an accurate trigger: ie. input (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)
