Hello
I'm in need of some help. I hope you people can shed some light. I am making a metronome with ATmega328 now i need to show a 3 digit number to display the current tempo selected. It will be put in a very small enclosure and I need a display but I don't know which one to chose. I have less than 40mm of space to put my display in. It needs to be very small, something like a watch display would be perfect i believe but I haven't seen anything similar to buy.
If anyone has any recommendations or maybe a different solution I'd be very grateful. Please help
Pick color, common anode (BA part #) or common cathode (BC part number).
How you control determines which you choose.
Easiest would be common cathode - drive current limit resistors to the anodes, select one 1 of 3 NPN transistors to sink cathode current to Gnd.

Thank you very much I've seen them but they seem to be a bit too big. Is there anything like a tiny lcd single color just to fit a couple of numbers?
