to sample the Pulse Sensor with consistent and regular timing. The code is setup to read Pulse Sensor signal at 500Hz (every 2mS). The reasoning for this can be found ...

The Arduino can wake up using an external reset, an external level interrupt on INT, pin change interrupt, timer interrupt, SPM/EEPROM ready interrupt, brown-out reset, watchdog interrupt, watchdog ...

This library enables you to use Interrupt from Hardware Timers on an ESP32-based board. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong ...

OK, year-old pop culture references aside [Kyle] dropped us a line to show us his tutorial on using interrupts with your Arduino. Given the single core nature of your average Arduino’s AVR you pretty ...
