Display a counting number on a 4-digit 7-segment LED display with an ESP32. Uses the SevSeg library to drive a common-anode display, showing elapsed time in 250ms increments. Demonstrates multiplexed display driving, digit selection, and segment pattern mapping. A great intro to display interfacing on the ESP32.
