Situation: You want to include a timer interrupt service routine in an assembly language program for an AVR-based Arduino. The program will be written, assembled and uploaded using the Arduino IDE.

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 ...

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 ...

Presented here is a simple timer kit built around an Arduino Uno board. It can be used to measure the time delay duration of devices like timer relays, circuit breakers, and other sequential logic ...
