[Scott-28] recently sent in a particularly well-documented project that turned an antique rotary phone into a digital kitchen timer using an internal Arduino.

This module allows you to develop a timing system, which utilizes the Arduino’s fast internal clock to provide an accurate timing system for kinematic experiments. Also, this module focuses on how to ...

The programmable timer features and up counter, down counter, and point accumulator that can be programmed manually using only one on-board button, or digitally with your Arduino or Raspberry Pi.
