The temperature outside is important, but if you would like to know what it actually ‘feels like’ outside, then taking the humidity into account is important as well. This beautiful comfort thermometer from YouTuber “dfgfdg7747” uses 517 individual LEDs embedded in a hand-drilled (using a drill press) piece of MDF to show the actual temperature, heat index, and humidity one-by-one on a timed cycle.
The display is housed inside an IKEA Ribba frame and controlled via four different processors, including an AVR and three PIC MCUs (both of which are now Microchip products). Signals for the temperature and humidity are transmitted wirelessly from a remote unit, so you can check the outside temperature before venturing out into the world.
Whilst the apparent temperature is being displayed on the 7-segment display animations on either the bargraphs LEDs or separate pink LEDs are simultaneously displayed. These simultaneous animations can be disabled with a switch on the reverse of the unit.
Tapping the right hand side of the frame cycles through various colours/animations on the outer 36 RGB LEDs illuminating the temperature/humidity numbers. Tapping the left hand side of the frame turns on/off the bargraph LEDs, just keeping the 7-segment display illuminated.
