No external power supply is required for the buttons themselves, as the contacts only transmit signals. Self-adhesive mounting saves time when assembling prototypes and allows the keypad to be quickly removed and repositioned.\u003c\/p\u003e \u003cp\u003eTypical applications include simple control interfaces for test setups, operating robotics projects with four directions of movement, or creating quiz and game devices with four answer options. The keypad is also frequently used as an input panel for LED projects in which each button triggers a different light or color pattern.\u003c\/p\u003e \u003cp\u003eThe buttons require pull-up or pull-down resistors at the microcontroller inputs to operate reliably. The self-adhesive bond is durable, but the keypad should be attached to a clean and dry surface. For long-term applications and installations that are frequently repositioned, additional mechanical fastening is recommended.\u003c\/p\u003e \u003ch3\u003eSafety Information\u003c\/h3\u003e \u003cp\u003eThe keypad is intended exclusively for building prototypes and for testing and development purposes.

It reads 125-kHz transponders and decides on site whether the detected ID is authorized to open the door. The device operates without an external control board and stores up to 2000 user IDs in its integrated memory. New IDs can be programmed directly on the reader or imported.\u003c\/p\u003e \u003cp\u003eThe reader detects the transponder identity contactlessly from a distance of a few centimeters. Detected and authorized IDs immediately activate the output relay, which switches the connected door opener or magnetic lock. At the same time, four separate sensor inputs can be monitored, for example motion detectors, door contacts, or alarm systems, and incorporated into the switching logic.\u003c\/p\u003e \u003cp\u003eApplications range from secured offices and storage areas to workshops, garages, and garden sheds. In a medical practice, for example, the system could allow authorized personnel to access the medicine cabinet and store an access log without requiring a central system to evaluate these accesses. The robust metal construction withstands moisture and dirt even in industrial and outdoor areas.\u003c\/p\u003e \u003cp\u003eOperation requires a regulated 12 V power supply with a capacity of at least 2 A.
