Hourglass and Tomato-timer with arduino

I made this timer for my efficient work.

The Tomato Hourglass built from:

• Arduino nano
• 4 x MD MAX7200 8x8 Led MAtrix
• 9 DOF Orientation Sensor
• RTC Real Time Clock module

The Tomato Hourglass have the following features:

• Mesaures work (25 min), short break (5 min), long break (10min) times
• Three position of orientation:
• • Normal clock
• • Work time measuring
• • Break time measuring

In Normal position shows the digital clock with 24H format In Standing position firstly starts measuring the work time.

• the remaining time shown
• shown a hourglass animation also If work time ends, blinking to set up upside down After turning, measure the break time, first short break, then again, and third time a long break. Can allways reset the Tomato Timer to put the device in normal position (clock)

Remaining works:

• needs a 3D printed case
• needs to bugfixing in arduino code
