Documentation – Week 4 – Arduino small project – Digital hourglass


Do a project from Arduino StarterKit book

I chose to do Project no. 8 – Digital hourglass

General information:

  • Software used: Processing IDE for Arduino
  • Arduino UNO & cables
  • LEDs from Arduino kit & tilt sensor from Arduino kit


1. Create the circuit

  • the schema of the circuit was offered in the book, thus we had just to follow it
  • moreover, I also reproduced it in Fritzing in order to practice using it.

2. Program the Arduino

3. The result

The result was that each next led was turned on at the interval =600ms and when reaching the end (thus all 6 leds were turned on) all the leds were turned off and the process started again.
