My Arduino UNO is on its way!
I am planning to build an advent calendar for my first project - I want it to automatically light the correct day.
I'm a software developer, so the code wont be a problem (Once aquainted with the syntax etc). What I'm not sure about is how to control the 25 bulbs required? i.e. There are 13 pins...how on earth would I wire this?
Looking for guidance rather than a solution. I want to ideally use 1.2v bulbs...or bright LEDs as they need to light a box for each day, which will be approx 10cm x 10cm
Any help will be much appreciated.
