with 74HC595 serial to parallel chips 256x dry contact inputs with 74HC165 chips R485 and 4x analog inputs (2x 0-5V DC, 2x 4-20 mA) on 8-pin terminal Misc – LED for each GPIO, 2x buttons (Reset and ...

Example performed using a NodeMCU v 1.0 ESP-12 variant. It should work with other ESP8266 hardware with changes to the gpios. There are two different code sketches. One that uses the ShiftIn() ...

Teaches you how to add digital inputs using the 74HC165 8-bit parallel-in serial-out (PISO) shift register IC. A KiCad schematic for a 74HC165 shift register IC, with an 8-position dip switch attached ...

74HC165 shift registers are a popular choice for adding inputs to a microcontroller. They have a parallel input register which can be read using the latch, then shifted into a microcontroller via ...

Thanks to the build log we know that [Linus] used 74HC165 input latches to monitor each of the switches for the 120 inputs. Fifteen of these latches work like a backwards shift register 74HC595 ...

By using sensor constructed by Hall switch component and 74HC165 8-bit parallel in/serial output shift register matrix, transmitter constructed by AT89C2051 MCU and 4~20mA industrial general current ...

Reference 1 details a technique for outputting signals with a single pin. The data from switch bank S 1 first presents itself to IC 3, a 74HC165 parallel-to-serial converter from NXP Semiconductors ...
