This way the microcontroller is concerned with the encoder signal only when a new pulse comes. Since the interrupt signal comes from outside the Arduino it is called as external interrupt. Arduino Uno ...

This tutorial will guide you through the ... the receiver shuts off a transistor connected to one of the Arduino’s external interrupt pins. He shows how to use this interrupt to measure the ...

[Ivan Voras] shows how to use interrupts to service the ESP32 analog to digital converters when sampling sound. Interestingly, he uses the Arduino IDE mixed with native ESP-IDF APIs to get the ...
