// #define WS2812B_NUM 2
// #define WS2812B_BRIGHT 32
// Enable Sending on Button Press, as well as Calibration by Pressing Button for 4s with MH-Z19C Addon
// The Button has to be connected to a pin that is capable of Fully Asynchronus Interrupts.
// For The ATTNode this means Pin PC2 if you don't want to block any other Interfaces
// #define BTN_PIN PIN_PC2
// Enable Serial Debugging. Parameters for the Serial Port are 115200
// Please be aware that the SG112A/B CO2 Sensor uses the HW-UART, so
// Serial Debug Output is not available with this Sensor.
