Get Product Serial Key

[Lines_of_codes]

By original if you want to get a serial key box (ex. Windows) then if you need it open a paper with serial key. but I have an idea to make

Products Serial Key - Arduino Serial Key (P.S.K.-A.S.K.)

then if you plug-in Digispark then open the program* that made by me name

Products Serial Key - Arduino Serial Key Reader (P.S.K.-A.S.K.R.)

*My Program use Microsoft .NET Framework 4.8 _{hope you know who install VS201x with Framework 4.8 don't have to install.}
And this use SerialPort Funtion
This is an example of code (4kb)**

Code: [Select]

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  //Baud Rate
}

void loop() {
  // put your main code here, to run repeatedly:
    if(Serial.available()>0)
  //check serial port then wait until it connect to pc
  {
   String txt=Serial.readString();
   if(txt=="abt-dev")
  //txt = textbox1 in application
   {
    Serial.println("S Universal Group")
  //println will return a message to richtextbox1 in application
    }   
    else if(txt=="get-serialkey")
    {
      Serial.println("G.P.I.S.K: 29/7/2019-001-1.0.2.1-infs-9600")
    }
    else if(txt=="abt-softwaren")
    {
      Serial.println("MoneyCalculate")
    }
    else if(txt="abt")
    {
      Serial.println("Products Serial Key - Arduino Serial Key (P.S.K.-A.S.K.) Use with P.S.K.-A.S.K.R (Reader)")
      Serial.println("Develop by S Universal Studio")
      Serial.println("Abt command = abt-softwaren (Software to get a serial key), abt-dev (tell developer group-name)")
      Serial.println("type 'get-serialkey' to get a serial key! ")
    }
  }
}**Serial Code are NOT availeble to use at this time. it can use only when i made this
