The вЂњVINвЂќ pin is connected to the plus of the power supply via a rectifying diode, which prevents damage to the module in case of reverse polarity voltage connection. The type of power supply should be selected according to the power requirements of the application you are creating based on the Arduino board.

Power can also be supplied via an on-board USB type B connector вЂ“ either when the Arduino is connected to a host computer or powered by a smartphone charger. A supply voltage of the same range, can also be supplied from the power supply to the contact plates or other similar module, by connecting them to the вЂњVINвЂќ pin. The recommended value of the output voltage from the power supply is between 7V and 12V DC. In Arduino, used for an auto-voltage selection circuit, but in reality, it operates as an auto.The first way is to connect an external power supply to the 5.5mm/2.1mm socket. To program the Microcontroller, an ICSP pin header is available on the board.

We use atmega16u Microcontroller for USB serial communication interface. We use the CH341A chip in many cheap programmers. USB Communication InterfaceДЇor USB/Serial communication, we use mostly two chips, CH341A or Atmega16U.Д¬H341a has used a USB interface chip for UART communication, It is a standard parallel port, memory parallel port, and synchronous serial (I2C, SPI Communication). We can use these pins,В As analog out/we can control the motor at different speeds.В Digital write() function used for high/low pins. We use digital out as High or Low even with PWM outputs function. A built-in led function through pin 14 (D13). From 0 to 13 used as general-purpose digitalВ in/out has internal pull-up resistors that can be high/low to ON/OFF maximum current per pin 40 mA.ДЄs showing in fig A from D0 to D13 pins. We use 14 digital pins as input or output. 1 TXD PCINT17 PD1 3 26 PC3 PCINT11 ADC3 A3 ARDUINO 2 INT0 PCINT18 PD2 4 25 PC2 PCINT10 ADC2 A2 UNO OC2B PWM 3. We cannot use less than o and over 5 volts for the AREF Pin. UNO ARDUINO THE UNOFFICIAL PINOUT DIAGRAM. AREF is used to set external analog input voltage. We use an analog reference pin for analog reference. AnalogwriteВ function () is very effective to operate the DC motors and varying led light in many electronic projects. Pin # 3, 5, 6, 9, 10, and 11 used for PWM functionВ (Pulse Width Modulation). Pin 2 & 3 can use as INT0 & INT1, we can configure it to act as external interrupts for a function written in the program. RX is to receive data, and TX to transmit the data. Pin 0 used as RX and 1 TX (in fig-A as D0&D1)used for TTL Serial Communication. A Wire library is available to communicate with different devices with the Arduino board. We use it for Iв¬ (inter integrated-circuit) / TWI (two-wire interface) communication. It contains 06 ADC (analog-to-digital converter)with a 10-bit resolution.В These Arduino pins have the functionality of general-purposeВ digital in/outВ pins.

PinВ A0 to A5В Used as analog input pins (for Sensors modules) used as analog output. We can use a 9V battery cell for the input supply voltage. It uses Vin pin for 7-12 VDC apply to the board as an external power source. These pins could be GPIO or using for specific signals. Blue color represents Power pins, Pink for analog input pins, Light blue for Digital pins, Green for communication, and Purple for PWM pins.ДЄrduino UNO board has analog/digital (PWM) pins. The Arduino board requires only 5V DC to operate.ДЄrduino Pins color shows pin functions. To program the main chip, a 16 MHz crystal is part of the board. The Atmega328P Microcontroller is an 8bit with 32k byte internal flash memory. Arduino also manufactured IoT (internet of things), Bluetooth, GSM/3G, Wi-Fi, and motion sensors boards. Arduino UNO Pinout and Board descriptionI will explain the description of the Arduino UNOВ PinsВ and the board in the post.В Arduino UnoВ is a standard board of the company, even though other boards e, g. Arduino Uno pinout Power Supply Barrel Jack The Barrel jack, or DC Power Jack can be used to power your Arduino board.
