کمک در مورد eprom

سلام دوستان
خوب هستین؟
می خواستم کمک کیند درمورد eprom آردوینو
من یه برنامه دارم که با ماژول بلوتوث کار میکنه ولی یه اشکال داره اینه که بعد ریست شدن وضعیت پین ها مورد استفاده ( آنالوگ) برمیگرده به صفر
که سوال کردم گفتن برو از حافظه ایپیرام استفاده کنن رفتم نگاهش کردم تو سایت اصلی ولی چیزی متوجه نشدم
لطفا کمکم کنین
خیلی ضروریه
اینم کد های برنامه من:

کد:

#include <SoftwareSerial.h> #include <Wire.h>//Include libraries: SoftwareSerial & Wire SoftwareSerial BT(11,12); //Define PIN11 & PIN12 as RX and TX pins //RGB LED Pins int PIN_RED = 3; int PIN_GREEN = 5; int PIN_BLUE = 6; //RED LED at Pin 13 int RED_LED = 13; String RGB = ""; //store RGB code from BT String RGB_Previous = "255.255.255)"; //preserve previous RGB color for LED switch on/off, default White String ON = "ON"; //Check if ON command is received String OFF = "OFF"; //Check if OFF command is received boolean RGB_Completed = false; void setup() { Serial.begin(9600); //Arduino serial port baud rate：9600 BT.begin(9600);//My HC-05 module default baud rate is 9600 RGB.reserve(30); pinMode(RED_LED, OUTPUT); //Set pin13 as output for LED, // this LED is on Arduino mini pro, not the RGB LED } void loop() { // put your main code here, to run repeatedly: //Read each character from Serial Port(Bluetooth) while(BT.available()){ char ReadChar = (char)BT.read(); // Right parentheses ) indicates complet of the string if(ReadChar == ')'){ RGB_Completed = true; }else{ RGB += ReadChar; } } //When a command code is received completely with ')' ending character if(RGB_Completed){ //Print out debug info at Serial output window Serial.print("RGB:"); Serial.print(RGB); Serial.print(" PreRGB:"); Serial.println(RGB_Previous); if(RGB==ON){ digitalWrite(13,HIGH); }else if(RGB==OFF){ digitalWrite(13,LOW); }else{ //Turn the color according the color code from Bluetooth Serial Port Light_RGB_LED(); RGB_Previous = RGB; } //Reset RGB String RGB = ""; RGB_Completed = false; } //end if of check if RGB completed } // end of loop void Light_RGB_LED(){ int SP1 = RGB.indexOf('.'); int SP2 = RGB.indexOf('.', SP1+1); int SP3 = RGB.indexOf('.', SP2+1); String R = RGB.substring(0, SP1); String G = RGB.substring(SP1+1, SP2); String B = RGB.substring(SP2+1, SP3); //Print out debug info at Serial output window Serial.print("R="); Serial.println( constrain(R.toInt(),0,255)); Serial.print("G="); Serial.println(constrain(G.toInt(),0,255)); Serial.print("B="); Serial.println( constrain(B.toInt(),0,255)); //Light up the LED with color code //**2014-09-21 //Because these RGB LED are common anode (Common positive) //So we need to take 255 to minus R,G,B value to get correct RGB color code analogWrite(PIN_RED, (R.toInt())); analogWrite(PIN_GREEN, (G.toInt())); analogWrite(PIN_BLUE, (B.toInt())); }

البته مقدار ارسالی برای ماژول این هستش:
مثلا:
89.65.15)
