What Else Do I Need?

To begin developing projects with Arduino, you will need various complementary products. The most practical ones are shield boards, which you can easily place on your Arduino board to perform functions such as controlling motors and communicating with communication modules. In addition, if you want to build your own circuits, you will need additional materials such as a breadboard and jumper cables. If you want to solve all of these needs in one go, you can also choose an Arduino kit.

You Can Prefer Arduino Sets When Buying Arduino. Why is that?

When you purchase an Arduino board, the only project that you can do without additional hardware is to blink the on-board LED for different periods of time. If you are new to Arduino programming, you can check out our affordable Arduino sets and find the one that suits your budget. By utilizing the included book or booklet, you can easily access various ready-made projects, sample codes, and application examples.

What are the Feature and Price Differences between the Clone Arduino Uno and the Original?

The Arduino is an open-source hardware, so all circuit diagrams and PCB models are available, allowing anyone to produce the Arduino board. Original Arduino boards are produced in Italy, while clone products are produced in China with lower production costs. As a result, the prices of clone Arduino models can be about 5 times lower than the original ones. The electronic components used and all functionality are the same as the original board. The chance of encountering any problems with the use of clone products is very low. The clone Arduino has the ATmega328 microcontroller, just like the original, but the integrated circuit is in SMD package, instead of DIP package as in the original. The use is the same, so you can choose the low-priced product with confidence. As with all our products, we offer a working guarantee for this product. If you encounter any problems, we will respond to your return or exchange requests.

Whether you are a beginner looking to get started with electronics or an experienced engineer looking to add physical computing capabilities to your projects, Arduino is a great choice. The Arduino UNO R3 is the latest model of the popular Arduino Uno series. It supports all the features of previous models (Uno, Duemilanove) and features a 16U2 model instead of the 8U2 model in previous versions. This results in faster data transfer and less memory usage. No drivers are required to connect Arduino to a computer on Linux or Mac systems, while on Windows systems, the inf file included in the Arduino IDE software needs to be installed. This allows you to use your Arduino like keyboard, mouse, joystick, and other accessories on your computer. The UNO R3 also has additional SDA and SCL pins, which are located next to the AREF pin on the board layout. Additionally, two new pins have been added next to the reset pin, with one being the IOREF pin for providing power to shields from the board and the other being a spare, unconnected pin for future use. The UNO R3 is compatible with all existing shields and also compatible with future shields due to its new pins.

Arduino Uno Pinout Diyagram

Power :The Arduino UNO can be powered either through the USB or an external power source. The external power source can be an AC-DC adapter or a battery. The adapter can be connected to the 2.1mm center-positive power socket on the board or the GND (-) and Vin (+) pins. The board does not require the USB to be constantly connected to function. The board can only operate with the adapter or the battery, allowing it to work independently from a computer. An external power source between 6-20V can be used, but these values are limits. The recommended external power source voltage for the board is between 7-12V, as the voltage regulator on the board may not work stably below 7V or overheat above 12V. The operating voltage of the microcontroller on the UNO board is 5V. The voltage between 7-12V given through the Vin pin or the power socket is reduced to 5V by the voltage regulator on the board and distributed to the board.

The power pins are as follows:

  • Vin: Voltage input pin between 7-12V when using external power supply.
  • 5V: This pin outputs 5V from the regulator. If the board only works over USB (5V), 5V from USB is output directly over this pin. If power is supplied to the board via Vin (7-12V) or power socket (7-12V), 5V from the regulator is output directly over this pin.
  • 3V3: It is the output pin of the 3.3V regulator on the board. Max. It can output 50mA.
  • GND: Ground pins.

Memory : The Atmega328P microcontroller has 32 KB of flash memory (about 0.5 KB is used by the bootloader). It has 2 KB SRAM and 1 KB EEPROM.

Input and Output: The UNO board has 14 digital pins that can be used as either inputs or outputs. There are also 6 analog input pins that can also be used as digital inputs or outputs. So, in total, the board has 20 digital input-output pins. All of these pins have a logic level of 5V. Each pin can operate with a maximum input and output current of 40mA. Additionally, some of the pins have special features, as specified below:

Serial Communication, 0 (RX) and 1 (TX): TTL Used to receive (RX) and transmit (TX) serial data. These pins are directly connected to the Atmega16u2 USB-serial converter on the board. In other words, these pins are also used when uploading a program from the computer to the card or when making mutual communication between the computer and UNO. Therefore, it is useful not to use these pins unless it is necessary to avoid errors while uploading a program to the card or while communicating.

External Interrupt, 2 (interrupt 0) and 3 (interrupt 1): These pins can be used as rising edge, falling edge, or change interrupt pins. For detailed information, you can check the attachInterrupt() function page.

PWM, 3,5,6,9,10 and 11: Can be used as 8-bit resolution PWM output pins.

SPI, 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK): These pins are used for SPI communication.

LED, 13: There is an internal LED on the board, marked with the letter "L", connected to pin 13 on the UNO. When the pin is set to HIGH, the LED will turn on, and when the pin is set to LOW, the LED will turn off.

Analog, A0-A5: UNO has 6 analog input pins with 10-bit resolution. These pins can also be used for digital input and output. The measuring range of the pins is 0-5V. By using AREF pin and analogReference() function, lower limit can be increased and upper limit can be lowered.

I2C, A4 or SDA pin and A5 or SCL pin: These pins are used for I2C communication.

AREF: Measurement reference pin for analog inputs.

Reset: When the microcontroller is reset, this pin is set to LOW. Reset can also be done with the reset button on the card.

You can check the pin mapping page between Arduino UNO and Atmega328.

Communication: The Arduino UNO has several options for communication with a computer, another Arduino, or a microcontroller. The Atmega328 has a UART TTL (5V) serial communication capability through its 0 (RX) and 1 (TX) pins. The Atmega16u2 USB-serial converter on the board opens a virtual serial port (COM port) on the computer, allowing communication between the Atmega328 and computer via the bridge it creates. The serial monitor in the Arduino IDE facilitates the exchange of text-based information between the Arduino and computer. When communicating via USB-serial converter with the computer, the RX and TX LEDs on the board will light up. The UNO has a hardware serial port, but the number of serial ports can be increased softwarely using the SoftwareSerial library. The Atmega328 also supports I2C and SPI ports, and the Wire library in the Arduino IDE can be used for I2C communication, while the SPI library is used for SPI communication.

Programming: The resettable fuse on the Arduino UNO protects your computer's USB port from short circuits or overcurrent situations. If the board draws more than 500mA of current from the USB port, it will automatically cut off the power from the USB for protection. Once the overcurrent situation or short circuit has been resolved, the fuse will return to its normal position and the connection will be reestablished.
