4×4 Matrix Keypad Interface on the Basys 3 FPGA | Verilog + UART Tutorial

Build a complete *4×4 matrix keypad interface* for the *Digilent Basys 3 FPGA* using **Verilog HDL**. You'll learn how to scan a matrix keypad, decode row and column inputs, blink the onboard LEDs when a key is pressed, and transmit each key to a PC over a **UART serial interface**. In this video you'll learn: • How a 4×4 matrix keypad works • Matrix keypad scanning in Verilog • Row and column decoding • Keypad scanner architecture • LED feedback using timers and counters • UART transmitter state machine • UART data frame format • Connecting a matrix keypad to the Basys 3 FPGA This project is ideal for students, hobbyists, and engineers learning FPGA design or preparing for more advanced embedded digital systems.
