Your Arduino reads these different voltage levels on a single analog pin, allowing you to detect which button is pressed with a simple analogRead() call — no extra digital pins needed.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this module compatible with boards other than Arduino UNO?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Any microcontroller board with at least one analog input pin (such as Arduino Mega, Nano, ESP8266, ESP32, or Raspberry Pi with an ADC) can use this keypad module. Just ensure the operating voltage matches your board's specifications (typically 3.3 V or 5 V).\u003c\/p\u003e\n\n\u003ch4\u003eQ: What quantity options are available for this keypad module?\u003c\/h4\u003e\n\u003cp\u003eA: This listing is available in three quantity options — 1 pc, 5 pcs, or 10 pcs — making it easy to stock up for multiple projects or workshop\/classroom use.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
