read the Raspberry Pi Pico's internal temperature sensor using a timer interrupt, display results with an SSD1306 OLED
debounce a switch using interrupts
This project demonstrates how to blink an LED using **Timer Interrupts** on an **ESP8266** board with **MicroPython**. A hardware timer periodically toggles an LED connected to **GPIO2** every second — no `while True` loop required!
Add a description, image, and links to the timer-interrupt topic page so that developers can more easily learn about it.
