Download Arduino Uno R3 Spi Pins Pics. However my arduino does not have those pins. Find arduino uno pin diagram, pin configuration, technical specifications and features, how to work with arduino and getting spi pins 10 (ss), 11 (mosi), 12 (miso) and 13 (sck):

These pins are used for spi communication. In this post i'll give you a complete and practical overview of the main arduino there are 3 main communication protocols you can use with an arduino uno board, through the pins of the circuit: The problem is that i need all the six pwm pins for six servos (including pin 10) which happen to be the default slave select pin for spi communication.

This function is called when a slave device receives data from the master.

Hello guys, you know what an arduino board is. Currently i am working on an arduino based project. The serial pins on the arduino uno r3 are also used by (for instance) the usb to serial chip when it communicates with a computer. In this post i'll give you a complete and practical overview of the main arduino there are 3 main communication protocols you can use with an arduino uno board, through the pins of the circuit:
