Contents

The chrono project is an ElN project done at the end of the first semester. It consists in conrtolling a stepper motor which moves a pointer in a clockwise direction. It will emulate a stop watch.

Chrono in Action

Specification

The basic specification is the following one:

  • On reset, the pointer moves to the start position (12 o'clock), it is given by a Reed sensor.
  • When pos 2 button (Start) is pressed, the pointer will start counting seconds.
  • When pos 3 button (Stop) is pressed, the pointer stops and waits at the actual location.
  • When pos 1 button (Reset) is pressed, the pointer resets to the start position (12 o'clock).

as optional task a pos4 button (Set) can be pressed in order to halt the pointer, but the stop watch is still counting. By a second push of the set button the pointer moves to the actual stop watch time.
