Countclock Hours And Minutes

The CountClock is a special clock that simplifies telling the time. It was designed with a very young audience in mind (children aged 2 to 7 years old), but the resulting clock may be appreciated by people of all ages.
The CountClock Hours & Minutes has two features that simplify reading off time: firstly, time can be told by counting the lights (thats why the clock is called CountClock) and secondly it has multiple learning levels that break down the confusing characteristics of a normal analog clock into separate learning steps of increasing difficulty.
The CountClock has been presented in a Meta Instructable (first published on January 29th, 2018) and has various separate Instructables explaining a number of aspects in more detail. The Meta Instructable is the best starting point for quickly overviewing the full series of publications (editorial note: currently not all info is up to date, but the Instructables are being updated over the days to come. Some links may not work yet, and the webshop may still be empty). The Instructable you’re now reading is the detailed Instructable regarding CountClock Hours & Minutes.
The control of the LEDs is being done by an Arduino board (Trinket Pro), driving 72 full-colour LEDs. The only hardware feature of the basic variant of the CountClock Hours & Minutes is a button on the backside, allowing to toggle between the various learning steps and display modes. This can be extended with multiple optional elements, such as a automatic dimmer for shading the LEDs, a bell that sounds the whole and the half hour, a device for keeping the time very precisely and a battery for cordless operation.”
