A very simple blind timer for poker tournaments. Includes a 16 unit string of MAX72XX LED matrices, ESP32 microcontroller, Active Buzzer to announce blind changes and a button to start, pause/unpause, advance blinds and reset.

Button operation...

• 1 click = pause / unpause
• Double click = advance blind level and reset timer
• Triple click = reset device (starts blind level back at 100/200)

Remote "Poker Pod" Displays Using EPS-NOW and LilyGo T-Display S3 Modules...

The poker blind timer can send the current blinds over WiFi using ESP-NOW to one or more battery powered "Poker Pod" modules so that players can have additional displays or use the "Poker Pod" as a card protector. See image below and GitHub repo here (https://github.com/bradrblack/poker-pods)
