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 ...

I've been trying to get the timer interrupt for the esp32 s2 working with the repeated timer example but it seems like that the esp32S2 is not going into the interrupts. This code uses native arduino ...

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 ...

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 ...
