The concept is to have a small device on a desk that looks like a digital clock that you can place a water bottle or cup on top of and the timer starts counting down 20 minutes. The timer is displayed below the clock on a 128x128 colour OLED. The numbers count down and the led lights change colour as the clock counts down from green to yellow to red. When the timer is done the OLED reads a message to encourage a drink break.
While we are currently using an Arduino we would like to change that out for something smaller. We are willing to buy specific parts if they provide better functioning. We currently have
Sparkfun DeadOn RTC Breakout - DS3234
VCNL4010 Proximity/Light sensor (Adafruit)
OLED 1.5' SSD1351 128x128 (Adafruit)
