題:
What is the pinout on the connector?
回答: The pin out is 1) Common, 2) key#1, 3) Key#2, 4) key#3, 4) and Key#4. If a key is pressed common is connected to that key's line. Key 3 pressed will connect pin 4 to pin 1. A common way to read the keyboard is to connect common to ground, and connect the other 4 wires to digital I/O input pins with pull up resistors (high when disconnected and low when grounded).
Adafruit Access-Control Keypads Editorial Review
The Adafruit Membrane 1x4 Keypad is advertised as a stackable Arduino Shield kit, but the pins on the connectors are not the appropriate length for stacking. Despite this flaw, the keypad has held up for a few months of regular use. However, it has intermittent connection issues and the cheap ribbon connectors are unreliable. The buttons require excessive force to register input, with one button rarely functioning properly. Overall, the keypad is decent but has significant flaws.
