The keyboard is an essential element for a microcontroller system, in order to assign the performance of the tasks to be performed, enter data, and be able to interact with the machine. This has a matrix of buttons that allows to use the pins of the microcontroller in an efficient manner. The 16 keys are mapped using only 8 data pins of the microcontroller, this will make the program very lean and easy to implement. The very small thickness allows to comfortably and easily install in any device.
16 buttons arranged in a 4x4 matrix (numbers 1 to 9, * and # keys, letters A, B, C, D)
