Arduino Diecimila Communication Protocol
- There are numerous features it has to connect with other categories of boards, controllers, and computers.
- It comes with the UART TTL serial communication through digital pins 0 (RX) and 1 (TX).
- Â An FTDI FT232RL at the board exists for serial communication through USB and FTDI.
- For sending and receiving simple data, there is a serial monitor is linked to it.
- The receiver and transmitter LED will blink when data is transferred.
Arduino Diecimila Components
Power
- The Arduino Diecimila board has features to get power from a USB connection and power supply connection. The power supply is used through the PWR_SEL jumper for delivery power to the board in USB connections
- This baord can work fro a voltatge range of 6 to 20 volts and provide with less than 7V normally but a 5V pin can provide less than 5V and the board will not be stable.
- If more than 12 volts are provided voltage regulator can get overheated and damaged. So recommended voltages are 7 to 12 volts.
These pis provide power to the board
VIN.
- The input voltatge for the Arduino board with using an external power supply is provided here.
5V.
- The regulated power supply is used for providing power to the controller and other board components. That can be from Vin through onboard regulators or provided through USB or regulated 5V supply.

PWM: 3, 5, 6, 9, 10, and 11.
- These pins provide 8-bit PWM output through the use of analogWrite() function.
SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK).
- These pins are configured with SPI protocol’
AREF.
- It is the reference voltage used for analog inputs with using the command analogReference().
Reset.

- ATmega168 uas support for I2C (TWI) and SPI communication.
Programming
- Arduino Diecimila can programmed with the use of Arduino software. The ATmega168 on the Arduino Diecimila has a preburrned bootloader that helps to upload new code without using an external hardware programmer.
- It programming communication with the use of STK500 protocol.
-  We can also bypass the bootloader and program ATmega168 with the use of ICSP (In-Circuit Serial Programming) header.
