Hi Ken
After much reading, playing, learning, cursing, etc, I have your PicAxe momentary switch circuit prototyped on breadboard and it works great
I reduced the pause time for the switch debouncing, which improved the responsiveness of the switch, without affecting the performance. At this point I've only got it driving an LED rather than a relay, to simplify the prototype, but don't anticipate any problems adding this later.
As I don't have PCB manufacturing facilities (maybe one day!), I'm going to transfer the circuit to veroboard. As it's pretty complex on breadboard (it's a mess), I'd like to design the veroboard layout in CAD first.
What software did you use to draw the schematic? Is it possible to have the original file for it? I'm currently deciding which bit of software to learn, I'm playing with LTSpice for simulation, but it seems Eagle is pretty popular for designing layouts, and it can be tweaked to do veroboard from what I have read. Would you recommend it? Is there another veroboard prototyping package that can import/create schematics and auto-route them onto a veroboard?
Any hints would be appreciated, as I'm probably going to have a bit of a learning curve, and would rather invest my time in the package that I'll continue to use (or buy).
Thanks
