| | Re: Digital outputs.
|

You can use solid state relays with 5 VDC inputs and DC outputs to control large loads. The inputs require very little current. It is less expensive to build transistor switches, which will do the same thing, but obviously much simpler to use (...) (24 years ago, 25-May-00, to lugnet.robotics.handyboard)

I'm still at my servo question :) the 3 servo routines so far use "normal" digital outputs. There are, according to the FAQ, 4 extra outputs I could use (SPI J6). Does this mean that I could write my own routines to drive 4 extra servos using these (...) (24 years ago, 23-May-00, to lugnet.robotics.handyboard)

Follow this link for data about the GP2D12. At the bottom, there is another link for Handy Board interfacing information. You have to cut a trace because the analog inputs on the Handy Board are connected to pullup resistors. The GP2D12 won't work (...) (24 years ago, 20-May-00, to lugnet.robotics.handyboard)
