Wiring up my 8 x 8 bicolour display
December 9, 2012
Hi All. Hope you are all having spiffing Sundays. Sorry, this isnt robotics, but dont find the guys over at arduinoCC especially helpful
I have fallen out of love with my Cyclops robot at the moment (as in, am now trying to think og additional functionallity to add to expand it, but am struggling somewhat) So i turn to my box of bits, and have found this!
Now i bought this with the idea of playing with Mr Conways Game of life and developing a version with slightly different rules, but annoyingly, this little fellah takes up ALL my Arduino Pins. Not to worry! i decided to solve this by buying a pack of Shift registers!
but APPARENTLY, if i wire this up to three Shift registers (one for the Anodes, and then one for each colour each for the Cathodes) i am likely to fry the chips.
This is where the advice comes in.
Should i cut my losses and buy an Adafruit Backpack version, and put what i have in storage (back pack is a ready built shield, with the same display, all chipped up and ready)
Should i cut my losses with the Shift registers, and buy some specific display chips?
Or, the last option, could i solve my issues by putting a transistor on every chip pin to protect it?
I think the transistors might be cool, because if i built Take offs on the Display pins, i could then wire up a bigger, more powerful display (bigger bulbs, rather than more lights) fairly easily? I am a bit of an electronic noob obviously, so a bit of advice, or a nudge in the direction of someoine who has sorted these issues would be greatly appreciated.
