Few weeks back I posted a tutorial on millis function where I was using this function to multitask, process slice in Arduino Code.

In this Tutorial I am showing you how to create delayed trigger mechanism.

I use it to build the eggtimer but it can be used in the veriaty of projects

The full tutorial can be found here:

EXPANDED TECHNICAL DETAILS

Precise Non-Blocking Countdown

This project provides a robust kitchen or laboratory timer that avoids the pitfalls of the delay() function, allowing for multiple concurrent tasks.

  • Temporal Differential Logic: The countdown is managed using the millis() function. The Arduino calculates the difference between the "Target Time" and "Current Time" on every loop, ensuring the timer remains frame-perfect even if other sensors are being read.
  • Rotary Encoder Navigation: Uses a robust rotary encoder for time setting. The Arduino IDE 2.0 Beta was used to implement a "Smooth Scrolling" algorithm; as the user turns the knob faster, the time increments in larger steps (1m vs. 15m).

Alerts

  • Dynamic Alarm Frequency: Once the timer hits zero, the Arduino triggers a 90dB piezo siren that ramps up in frequency, ensuring the user hears it from across the house.
