By using this simple capacitor-network circuit and software, designs using the Arduino Uno need only two I/O pins to read a hex-switch decoder, leaving the remaining pins for other functions.

DNA has been used as a building block to construct a series of complex logic circuits to perform nonarithmetic functions, including a multiplexer, demultiplexer, encoder and decoder. This is the ...

RF Solutions has introduced a pair of encoder/decoder ICs for radio-control applications, featuring three independent I/O lines and allowing direct connection of an RF module to simplify design.

A solid-state relay (S201S02-from Sharp) at the output of the circuit enables larger ac mains operated loads (for instance, the solenoid valve) to be switched. How the infrared switch is working. At ...
