Food dispenser Code

Arduino
This code will allow you to use the limit switch as well as Blynk to dispense food. The code will allow the duration of the dispenser, dispensing food to be changed in Blynk, and to show the display on the app interface, how long the dispenser will dispense food.
#define BLYNK_PRINT Serial  // Set serial output for debug prints
//#define BLYNK_DEBUG       // Uncomment this to see detailed prints

// Go to the Project Settings (nut icon).
