What are the different pins on an Arduino?

What are the different pins on an Arduino?

Introduction to the Arduino Board

  • Analog Reference pin (orange)
  • Digital Ground (light green)
  • Digital Pins 2-13 (green)
  • Digital Pins 0-1/Serial In/Out – TX/RX (dark green) – These pins cannot be used for digital i/o (digitalRead and digitalWrite) if you are also using serial communication (e.g. Serial.

What is the use of 3V 3 pin present in various Arduino boards?

This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.

What are two two main types of Arduino pins?

The Arduino has several different kinds of pins, each of which is labeled on the board and used for different functions.

  • GND (3): Short for ‘Ground’.
  • 5V (4) & 3.3V (5): As you might guess, the 5V pin supplies 5 volts of power, and the 3.3V pin supplies 3.3 volts of power.

What kind of pinout does the Arduino Uno use?

Arduino Uno is based on the ATmega328 by Atmel. The Arduino Uno pinout consists of 14 digital pins, 6 analog inputs, a power jack, USB connection and ICSP header. The versatility of the pinout provides many different options such as driving motors, LEDs, reading sensors and more.

What kind of voltage do you need for Arduino Uno?

Above 12 volts, the regulators might overheat, and below 7 volts, might not suffice. VIN Pin – This pin is used to power the Arduino Uno board using an external power source. The voltage should be within the range mentioned above. USB cable – when connected to the computer, provides 5 volts at 500mA.

What are the pins for a PWM on Arduino?

The Arduino Uno pins compatible with PWM are the pins 3, 5, 6, 9, 10 and 11. So you have 6 pins where you can create a PWM, using the analogWrite () function. This can be quite useful to control some actuators that require a fine voltage tuning, and are not only switched on or off.

What kind of power supply does an Arduino use?

Arduino Uno pinout – Power Supply. There are 3 ways to power the Arduino Uno: Barrel Jack – The Barrel jack, or DC Power Jack can be used to power your Arduino board. The barrel jack is usually connected to a wall adapter. The board can be powered by 5-20 volts but the manufacturer recommends to keep it between 7-12 volts.

What are the 3 main pin sections in Arduino?

The major components of Arduino UNO board are as follows:

  • USB connector.
  • Power port.
  • Microcontroller.
  • Analog input pins.
  • Digital pins.
  • Reset switch.
  • Crystal oscillator.
  • USB interface chip.

How many amps does Arduino output?

The maximum current draw of the Arduino is 200mA. It’s unlikely that the Arduino itself will draw 200mA, but let’s assume that between the Arduino and the other devices connected to it, they draw a total of 200mA.

What does high mean in Arduino?

HIGH. The meaning of HIGH (in reference to a pin) is somewhat different depending on whether a pin is set to an INPUT or OUTPUT . When a pin is configured as an INPUT with pinMode() , and read with digitalRead() , the Arduino (ATmega) will report HIGH if: a voltage greater than 3.0V is present at the pin (5V boards)

What is a pin in Arduino?

Pins (5V, 3.3V, GND, Analog, Digital, PWM, AREF) The pins on your Arduino are the places where you connect wires to construct a circuit (probably in conjuction with a breadboard and some wire. They usually have black plastic ‘headers’ that allow you to just plug a wire right into the board.

How do you use Arduino?

Arduino is a popular open source circuit board with a microcontroller to develop electronic projects. It’s IDE provides you the facility to write and upload program to the physical board. In this way you can use arduino to make projects like to control motors, LEDs, cameras, use different sensors or even build a simple robot.

What is the voltage of Arduino?

The Arduino has a narrow operating voltage around 5 Volts (3.3 Volts in some) and is sensitive to variation in this voltage. The Arduino design is based on the assumption that a stable 5 Volt power source will be feeding the chip at the heart of the Arduino.
