Coffee Scale Timer (Arduino-Powered)

☕ Coffee Scale Timer (Arduino-Powered)

Coffee Scale Timer is a compact, single-button scale and timer designed for precision coffee brewing. It runs on an Arduino Nano, using an HX711 load cell amplifier and a 128×64 OLED display to show real-time weight (in grams) and a clean brew timer.

⏱️ Simple and intuitive operation:

• Short press the button to start, pause, and reset the timer
• Long press (1s) to tare the scale without triggering the timer

🔩 Load cell mounting requires basic hardware:
2× M4 and 2× M5 socket head cap screws
