Out of these 32 pins, 14 are digital I/O pins, 6 are analog pins, 3 GND and single 5V,3.3V, Vin and reset pin, and more. If you take a look at the Arduino board you will find that there are a total of 32 pins on it(excluding the ICSP header). Of course, you can add multiple tasks in a single program but they will be executed one by one. Unlike your laptop or mobile phone, it can run only one program at a time. Īrduino UNO is a simple microcontroller board without any operating system or powerful processor.

You can say, atmega328p is the brain of the Arduino UNO development board. 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. Then, the module’s GND is connected to one of the Arduino’s GND pins. First, we connect the module’s VCC to the Arduino’s 5V pin. In this tutorial we will make use only of the first four pins: VCC, GND, SDA, and SCL.

ARDUINO MEGA VS UNO PINOUT HOW TO

The TXD is used to transmit the data, and RXD is used to receive the data. Fritzing file that shows how to wire the GY-521 breakout board to an Arduino Uno. The digital input/output pins are 54 where 15 of these pins will supply PWM o/p.

The input voltage will range from 6volts to 20volts. The recommended Input Voltage will range from 7volts to 12volts. The operating voltage of this microcontroller is 5volts.

ARDUINO MEGA VS UNO PINOUT SERIAL

TXD and RXD-TXD and RXD pins are used for serial communication. The specifications of Arduino Mega include the following.

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. MOSI-It stands for Master Output/ Slave Input.This data line in the MISO pin is used to receive the data from the Slave. MISO-It stands for Master Input/ Slave Output.The Arduino Mega has in total one 3. These are the clock pulses, that is used to synchronize the transfer of data. Because the Mega is the biggest Arduino microcontroller, this beast has the highest number of pins and is therefore suitable for large projects where a lot of devices have to be connected to the microcontroller. It is used by microcontrollers to communicate with one or more peripheral devices quickly. SPI stands for Serial Peripheral Interface.
