Smart Coaster using ATtiny85 and mlx90615

Connect to usb battery or PC, cable usb only use vcc/gnd. Green when no object on top.
With a heavy object, pushbutton HIGH, sensor read temperature. Blue with ice, yellow/red with hot water. On stl no hole for cable, I used a drill.
In code T1 to T4 level for colors/temperature
I used an CJMCU LilyTiny (AtTiny85) as MCU, for temperature reading an MLX90615, for leds a ring of 16 led WS2812. Libraries for mlx and Neopixel for leds.
