SIPO and PISO shift registers with Arduino and ESP (ESP8266 / ESP32)
When working with Arduino, ESP8266 or ESP32, you quickly hit a simple limit: not enough GPIO pins.Instead of stacking boards or using complex expanders, there is a very clean and proven solution: shift registers. The two main types are: Why use shift registers? With only 3 pins, you can manage 8, 16, 32+ inputs or […]
