TM1637 Button Counter
Displays · Board: ESP8266 · Day 16 of 100
Count button presses on a bright TM1637 4-digit display with the ESP8266. Two-wire display driving without the bulk of an LCD.
How it works
Each button press is detected as a clean rising edge after debouncing, and the count is pushed to the TM1637 over its two-wire protocol. Four bright digits show the total with far less wiring than a character LCD needs.
What you'll learn
- TM1637 display protocol
- Edge detection
- 4-digit multiplexing
- Minimal-wire displays
