How to use a timer interrupt to blink an LED at a fixed rate?

Here’s a real-world pattern: use a hardware timer interrupt to blink an LED at a fixed rate while the main loop keeps doing other work (e.g., reading sensors, talking over serial). I’ll show an Arduino Uno (AVR) version first, then quick notes for ES...
