I am building Yellow Drum Machine, (YDR).
I have set up the basic caterpillar tracks(note how most machines are yellow, it is a law of nature with caterpillar tracks, aparently), and 2 drumsticks. In other words, the usual & basic stuff for an YDR!
And I have lots of plans and ideas for different things it should do.. But I now realize that I may run out of outputs from the board, standard 28pin picaxe board. And I would hate to make it a dual-core project, I am pretty tired of them at the moment, too many wires, 2 chips to program etc, it takes out some of the fun, I am more into keeping it simple in these days.
So I have to plan, which is also not what I usually like to do when building robots for fun. And then I thought that I might as well do it in here instead of opening notepad or similar, getting a blog-entry out of it at the same time :)
Outputs available:
Standard:
- 0
- 1
- 2 Stick 1
- 3 Stick 2
- 4 Motor
- 5 Motor
- 6 Motor
- 7 Motor
Many inputs on the Picaxe 28 can be reversed to outputs, this gives me these extra:.. Hmm.. hang on - it depends on the version of the Picaxe 28.. Mine is 28X1 (Options in the programming editor, "firmware").. ok.. X and X1 have same ins and outs..and so I have this extra:
- Out c0 .. No I will need that for input of SRF05 for navigation
- Out c1
- Out c2
- Out c3
- Out c4
- Out c5
- Out c6
- Out c7
Hmm!! Aparently that leaves me with 9 more outputs, and I still have 4 analouge inputs!
OK, back to just building, ins-and outs are no problem, I can add 9 extra drumsticks, I think that will do!
