The 38-KHz IRTR module is a compact design of an infrared transmitter and receiver board created with the help of a couple of inexpensive components. This builds off of the IR Decoder that we explored ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
