Hey everyone . I have been searching for the past two days for a example and a setup on how I can make a small 2 digit display that counts the amount of time a loop repeats itself. I have a client who is looking to turn his commercial traffic light into a power hour drinking game, and I have a few ideas on how to incorporate some addressable leds, but I’d really like to be able to add a counter on how we many times this loop has repeated. Any examples? I’m not much of a coder, so really I’m looking for a example that i may be able to implement in this.

Thanks

Here’s some code I put together recently for simulating the old 7 segment displays. Is this what you’re taking about?

//***************************************************************
//  Two digit seven segment number display example using CRGBArray and CRGBSet.
//  A number from 0-99 can be displayed.  This demo repeats counting from 0 to 25.
//
//  For this example the number segments are wired in the following layout:
//  http://imgur.com/cgabMfK
//  It also assumes that each segment has the same number of pixels.  There is
//  a variable below which allows the number of pixels per segment to be changed.
//
//  This example uses 5 Pixels Per Segment (pps).
//  5pps x 7segments x 2digits = 70 pixels total
