Note: One of my first projects in the C language.
It started on January 25, 2016.
The project contains the firmware for the light box of a commercial refrigerator.
At the moment, only the prototype board and its photograph are available.
The device allows PWM control of the LED panel of a commercial refrigerator. It is built on an ATtiny13A controller and uses a resistive light sensor to control the brightness of the backlight.
