BotronikS - Final code for all types of Arduino and PC users: -- HOME -- email: botronik@gmail.com

Codes tools:
Download the Free! HEX codes below, unpack and upload to the proper Arduino board (Use a free net tool for example XLoader)
Blink (Turn an internal LED on and off - The most common Arduino default code.: Nano/Uno(HexCode-m328) - Mega(HexCode-m2560)
BlinkSerial: Blink and PC value of LED (Termite - Baud=9600) : Nano/Uno(HexCode-m328) - Mega(HexCode-m2560)
EepromDefaultState: Write all eeprom bytes to 255. Led on when done.: Nano/Uno(HexCode-m328) - Mega(HexCode-m2560)
EepromRead: Read all addressed bytes from eeprom on PC.: Nano/Uno(HexCode-m328) - Mega(HexCode-m2560)
EepromWriteString: Upload code: Nano/Uno(HexCode-m328) - Mega(HexCode-m2560). Then do next:
---- Connect A0 to GND, Open Termite. Do reset on Arduino button. Some text apear: SV10-SV12=YourMsg1-3 (max 20 chars long each). Disconect A0 and reset.
 
Note for used arduino: Do EepromDefaultState and EepromRead (optional) and Blink. Then you can storage arduino or upload new code.
