General Information

This project is part of a series of explorations I made into the realm of embedded devices for the home.

In essence it is a pomodoro device that utilises coloured light to indicate time intervals, creating a more subdued experience of productivity.

The coloured light is shone down onto the keyboard/workspace to indicate session cycles. The sessions are configured, started and stopped with capacitive touch buttons.

Technology Used

The prototype is built on the Arduino framework implementing various modules for functionality.

• DS3231 Real-Time Clock for tracking time during meditation sessions
• RGB LED light strip
• 3 x TIP122 NPN transistors for powering the LED strip
• 3 x capacitive touch buttons for control and power

Project Status

• Unit-testing
• User-testing
• Transfer to PCB
• Device design and prototyping
