ARDUINO Sketch program
Fig. 1
How does it operates:
Please, before write C++ program codes on the strings of program and then verify it. If there are not red messages on the low black screen and on the green panel of program is the message "Done Compiling", the sketch was written without error [Fig. 2].
Fig. 2
Saving sketch INO-file:
When operation had been done the compilation completely, please, press on the button of program panel File\Save [Fig. 3]. Then include folder, rename on the "File name" and "Save" it [Fig.4] or save, pressing on the red button "Close" which is placed on up side right on the panel of program.

Fig.4
Compilation INO-file to HEX-file or BIN-file:
When our sketch INO-file already is saved in the certain folder, for example, Arduino, we search and open this file. When our INO-file had been opened, we press on the button "Sketch" and then here press on "Export compiled Binary" and after completely compilation it exports two HEX-files [Fig.5].
Fig.5
Here always save two HEX-files eight analog input and boot-loader:
The "eight analog input" is for programming the programmable read-only memory (PROM); rather "boot-loader" is for flashing the flesh-memory.
By analog signals winking by the light-emitting diodes on the four pins.
