This design performs quadrature decoding with ... digital signal indicating direction is called quadrature decoding. The circuit shown in Figure 2 initially debounces the switch signals.

Using eight digital inputs, this circuit simplifies decoding of the common membrane ... can be considered with this device. The design uses eight pre-biased transistors—four NPN and four PNP.

He first built a breadboard decoder circuit that would light 1 of 16 LEDs depending on the detected button press. This was well and good, but he decided that an Arduino-driven LCD display would ...

Decoding this bit stream into ASCII hex values is an ideal job for a low-cost 8-bit microcontroller. Using a microcontroller with onboard flash memory, such as the NEC Electronics µPD78F9418A ...
