Descrição
Arduino NANO Kitchen timer using a stepper motor driven "Rolling Ball Escapement"
Full build details on my web site here http://www.brettoliver.org.uk/Rolling_Ball_Timer/Rolling_Ball_Timer.htm
This is a general purpose kitchen timer.
The timer uses a 3D printed Rolling Ball Escapement from JBV Creative.
This must be purchased seperatly from here https://jbvcreative.com/products/the-rolling-ball-escapement
The original Rolling Ball Escapement was driven by a weight and string pulling on a ratchet gear.
I have replaced the weight with a stepper motor controlled by an Arduino NANO.
Time remaining is displayed on a 8 digit 7 segment LED display along with other functions.
The timer sound is provided by a JQ9500 sound module that can play any MP3 sound files as the timer alert.
