Every input-driven project needs a way to type in numbers or trigger commands, and the 4×3 Matrix Membrane Switch Keypad Arduino is a neat, low-profile way to do exactly that — grab it from Tech Depot India for just Rs 87. If you've been itching to add a keypad to your next Arduino build, this compact 4×3 membrane pad is a fun, cheap place to start.

What is the 4×3 Matrix Membrane Switch Keypad Arduino?
It's a flat, flexible membrane keypad arranged in a 4-row by 3-column matrix — the classic layout you'll recognise from old telephone keypads — built to be read by an Arduino board using matrix scanning. Being a membrane pad rather than mechanical buttons, it's thin, light, and easy to mount onto an enclosure.
Because it's a matrix keypad, wiring is simple: a handful of pins for rows and columns instead of one pin per button, which keeps things tidy on smaller Arduino boards. Full pin details for the 4×3 keypad are on the product page.
