It is actually a development board that uses a microcontroller called Atmega328p to perform various functions. Is Arduino a Microcontroller or Microprocessor?Īrduino UNO is neither a microprocessor nor a microcontroller. Since this was the first official Arduino board released by the company, hence the word UNO in it. Yes, it’s a Latin word and does not have any full form. What is the full form of UNO in Arduino UNO? Mechanical Diagram of Arduino UNO Datasheet of Arduino UNO Rev3ĭownload the official Datasheet of Arduino UNO Rev3, from here. It also represents the successful flow of data. The TXD is used to transmit the data, and RXD is used to receive the data. TXD and RXD-TXD and RXD pins are used for serial communication. This allows us to have multiple SPI peripheral devices sharing the same MISO, MOSI, and CLK lines.Įxternal Interrupts (2 and 3)- These pins can be used to trigger an interrupt on a low value, a rising or falling edge, or a change in value. When it’s value HIGH, it ignores the master. When a device’s Slave Select pin value is LOW, it can communicate with the master. This line is used for sending data to the peripherals.
