Display recommendation

Using Arduino Displays
#1

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

Thank you for your help in advance :)

37.6 x 19mm outer dimension

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?

Look at www.newhavendisplay.com

Or try SMD version of the same display.

Thank you I managed to find the 0.25 inch 3 digit 7 segment display. I didn’t know they made them in all those sizes :slight_smile: Thanks again for your help!
