A keypad is a block or pad of buttons set with an arrangement of digits, symbols, or alphabetical letters. Pads mostly containing numbers and used with computers are numeric keypads . Keypads are found on devices which require mainly numeric input such as calculators , television remotes , push-button telephones , vending machines , ATMs ...
The switches for each key are connected to the microprocessor chip using a matrix circuit. Even though the SY77 has 61 keys, only two small ribbon cables of wiring comes from the keyboard matrix. There are at least two limitations with this system. The first is that it provides only a crude binary on/off signal for each key.

Board real estate and wiring savings compared to a parallel bus are significant, and have earned SPI a solid role in embedded systems. That is true for most system-on-a-chip processors, both with higher-end 32-bit processors such as those using ARM , MIPS , or PowerPC and with lower-end microcontrollers such as the AVR , PIC , and MSP430 .
Hot-swappable keyboards are keyboards in which switches can be pulled out and replaced without requiring the typical solder connection. [7] [8] Instead of the switch pins being directly soldered to the keyboard's PCB, hot-swap sockets are instead soldered on. Hot-swap sockets can allow users to change different switches out of the keyboard ...
Thinking of plants as lives that serve their own purposes opens up a distinct way of understanding our connection to them. They are independent from us and yet knowable; otherworldly and yet familiar.
A gated SR latch circuit diagram constructed from AND gates (on left) and NOR gates (on right) A gated SR latch can be made by adding a second level of NAND gates to an inverted SR latch. The extra NAND gates further invert the inputs so a SR latch becomes a gated SR latch (a SR latch would transform into a gated SR latch with inverted enable).
