Where did you place the sensor? At the top of the stairs or at the bottom or did you get a bunch?
I'm thinking about doing the same thing and was glad to run across this article. I'm new to all of this and was wondering if you had a schematic that you worked from or did you go from the TLC5940 data sheet. Also Sparkfun has a TLC5940 breakout board that I was thinking about using in conjunction with the common anode LEDs you used https://www.sparkfun.com/products/10616?, do you have any thoughts on using it?
I never done anything close to electronics
QuoteI never done anything close to electronicsThis is definitely _not_ a project to start with. First one blinks a led. Then a few leds. Then a lot of leds. Then one rgb led, then a few rgb leds, then a lot of rgb leds. Meanwhile one learns blink without delay and debouncing, and led sequences, and state-based programming and so on.Also, a club is a public place, so safety regulations must be taken into account. Say you light up the entire stairs for half an hour and something gets so hot it could start a fire... Pretty scary...A good consultant is what you need, IMVHO.
