1 ARDUINO NANO INTRODUCTION Arduin nan differ frm ther Arduin as it very small s it suitable fr small sized prjects and it supprts breadbards s it can be plugged with ther cmpnents in nly ne breadbard. ARDUINO NANO PHYSICAL COMPONENTS Micrcntrller In Arduin Nan 2.x versin, still used ATmega168 micrcntrller while the Arduin Nan 3.x versin already used ATmega328 micrcntrller. 1

8 ARDUINO NANO PIN CONFIGURATION The Serial Peripheral Interface (SPI) IN PINS 7,8,13,14 AND 15 Serial Peripheral Interface (SPI) is a synchrnus serial data prtcl used by micrcntrllers fr cmmunicating with ne r mre peripheral devices quickly ver shrt distances. It can als be used fr cmmunicatin between tw micrcntrllers. With an SPI cnnectin there is always ne master device (usually a micrcntrller) which cntrls the peripheral devices. Typically, there are three lines cmmn t all the devices: MISO (Master In Slave Out) - The Slave line fr sending data t the master, MOSI (Master Out Slave In) - The Master line fr sending data t the peripherals, 8

9 SCK (Serial Clck) - The clck pulses which synchrnize data transmissin generated by the master and ne-line specific fr every device: SS (Slave Select) - the pin n each device that the master can use t enable and disable specific devices. When a device's Slave Select pin is lw, it cmmunicates with the master. When it's high, it ignres the master. This allws yu t have multiple SPI devices sharing the same MISO, MOSI, and CLK lines.
