The Arduino Uno board has a rearrangeable poly fuse that defends the USB port of the PC from the over-voltage. Once this process is completed, check the LED flash on the board. When the programming codes are dumped into the IDE, and then click the button ‘upload’ on the top bar. To activate the Arduino board & flash the LED on the board, dump the program code with the selection of Files–> Examples.>Basics.>Flash. This board can be programmed with the help of an Arduino programming language depends on Wiring. Open the Arduino IDE & select the right board by choosing Tools–>Board.>Arduino Uno, and select the right Port by choosing Tools–>Port. Once the Arduino IDE tool is installed in the PC, attach the Arduino board to the computer with the help of USB cable. Arduino projectscan communicate by software while running on a PC. The ATmega328 microcontroller on the Arduino board can be programmed with the help of an Arduino programming language and the IDE (Integrated Development Environment). Here the input is a variety of sensors and these can affect its surroundings through controlling motors, lights, other actuators, etc. How to Use an Arduino Uno?Īrduino Uno can detect the surroundings from the input. The Arduino software contains a wired library for simplifying the utilization of the I2C bus. There are two LEDs on the board like RX & TX which will blink whenever data is being broadcasted through the USB.Ī SoftwareSerial library permits for serial communication on Arduino Uno digital pins and the ATmega328P supports TWI (I2C) as well as SPI-communication. The software of an Arduino has a serial monitor that permits easy data. The Arduino Uno ATmega328 offers UART TTL- serial communication, and it is accessible on digital pins like TX (1) and RX (0). The memory of this Atmega328 Arduino microcontroller includes flash memory-32 KB for storing code, SRAM-2 KB EEPROM-1 KB. Reset Pin: This pin is used for reset (RST) the microcontroller. Pin-4 (SDA) & Pin-5 (SCL) (I2C): It supports TWI-communication with the help of the Wire library.ĪREF (Reference Voltage): The reference voltage is for the analog i/ps with analogReference(). As the HIGH-value pin, the light emitting diode is activated, whenever the pin is LOW. Pin-13(LED): The inbuilt LED can be connected to pin-13 (digital pin). The suggested voltage range will be 7 volts to 12 volts. Similarly, the batteryleads can be connected to the Vin pin and the GND pin of the POWER connector. The adapter can be connected to the Arduino Uno by plugging into the power jack of the Arduino board. The external power supplies mainly include AC to DC adapter otherwise a battery. The Arduino Uno power supply can be done with the help of a USB cable or an external power supply. The Arduino UNO board description is discussed below. The Arduino Uno board can be built with power pins, analog pins, ATmegs328, ICSP header, Reset button, power LED, digital pins, test led 13, TX/RX pins, USB interface, an external power supply. DC Current for each input/output pin is 40 mA.The input voltage ranges from 6v to 20V.The recommended input voltage will range from 7v to 12V.The voltage regulator allows to use up to 18V as an input value, however we do not recommend exceeding the recommended values aforementioned, since this can lead to excessive heat and damage the device. The maximum output current for 5V is around 800mA, while for 3.3V it is about 800mA. The used voltage regulator operates in a range of 6 to 9V DC. The board can be powered directly through the Micro USB connector, or via the corresponding contact on the board (Vin). The board has a Micro USB connector that allows you to connect the microcontroller to the computer via the USB-UART adapter CH340(A driver installation may be required).Ĭonnectivity to the computer is provided through the common micro USB connector (universally used by most phones, including Android smartphones). It uses the original chip, and a 16 MHz high-quality quartz resonators is present on the board. Even though it is an Embed board, it is solid stable as the Mega Board. The Mega Pro Embed functionalities are identical to the Arduino Mega 2560. It has a compact form factor of 38 x 54mm and is an excellent solution for developing projects based on ATmega2560. The "Arduino Mega 2560 Pro Mini" board is compatible with the Arduino Mega 2560. But the size, pinout, circuit and functionality will be identical. The boards might look slightly different than in the pictures(like text on board). Please Note: This is a generic board, and can be manufactured by a variety of different manufacturers. It is assembled with a genuine Atmel ATmega2560 microcontroller and the low cost CH340G USB-UART interface. This is a low cost and miniature version of the popular Arduino Mega 2560.
