Why do I get these errors?

[yossi_dror]

Hi,
I'm trying to set a new code for NANO Every board - starting by setting the board i/o pins for input and outputs but I keep getting the compiler errors all the time ...
Can you help ??

[code]
/*
  Dropper

  Set water drops for Macro photography.
  Set drops size and interval, display the time intervals on LCD ,set camera shutter interval .

  model, check the Technical Specs of your board at:
  https://www.arduino.cc/en/Main/Products

  Edit: Yossi Dror , 14 July 2021

  Modules:

  Start_drop_sw   D2  Digital input pin
  flash_fire_out  D7  Digital output pin

Why are the digital pins prefixed with D ?
Only needed for Analog (A) pins.

[paulpaulson]

Hello
Yes, I can
change

const int Start_drop_sw  = D2;     // the number of the pushbutton pin
const int Selonoid       = D4;      // the number of the LED pin
const int Camera_Focus   = D5 ;   // pin D5 start focusing the camera
const int Camera_Shutter = D6 ;   // pin D6 fire the camera
const int Flash_Fire     = D7;   //  pin D7 fire the flash

to

const int Start_drop_sw  = 2;     // the number of the pushbutton pin
const int Selonoid       = 4;      // the number of the LED pin
const int Camera_Focus   = 5 ;   // pin D5 start focusing the camera
const int Camera_Shutter = 6 ;   // pin D6 fire the camera
const int Flash_Fire     = 7;   //  pin D7 fire the flash

and have a nice day.

I will try!!
thanks a lot

Why 'void loop()' is in commented? No 'void loop()', no compilling code.
