While there are a lot of projects on crowd funding sites which are pretty lazy "we don't have a business plan, so thought we'd ask everyone to send us cash instead", this one looks like a pretty good cause - Tom the designer is an A level student trying to do something pretty cool so deserves support.
He's got a few examples of how to control the thing in Python, but like most Python codes the make the whole thing look pretty complex, when in fact using this is dead simple:
make up digital output 4
.set rst to on
.wait 5 millisecs
.set rst to off
.repeat count
..wait 5 millisecs
..set up to on
..wait 5 millisecs
It uses two pins 15, and 17 which we've called rst (reset) and up. All we have to do is pulse rst to set the count to zero, and then pulse up to increase the value by one, so we loop count times to set it to the value we want (leaving a little delay just to make sure things have time to happen).
Now we can add it to any program just by saying:
.forever
..set count to pick random 1 to 6
..broadcast update
..wait 1 secs
If you think one of these would be fun to have you can get one for £10 (if you're quick) from http://www.indiegogo.com/projects/7seg-for-raspberry-pi.

Good luck Tom!

ReplyDeleteIt was very fascinating to know that A young A-level student is going to take this much responsibility. I would definitely be going to support such talented students.
