This app will display the real time level of the trash with three Leds placed vertically on the Blynk application. Green represents the range from 0 to 25%, Orange from 25 to 60% and Red from 60 to 100%.

// You could use a spare Hardware Serial on boards that have it (like Mega)
#include <SoftwareSerial.h>

#define BLYNK_PRINT DebugSerial
#include <BlynkSimpleSerialBLE.h>

// You should get Auth Token in the Blynk App.
