What are pins in Arduino Uno?
Arduino Uno Pinout Configuration
| Pin Category | Pin Name | Details |
|---|---|---|
| Input/Output Pins | Digital Pins 0 – 13 | Can be used as input or output pins. |
| Serial | 0(Rx), 1(Tx) | Used to receive and transmit TTL serial data. |
| External Interrupts | 2, 3 | To trigger an interrupt. |
| PWM | 3, 5, 6, 9, 11 | Provides 8-bit PWM output. |
How many 5V pins are there in Arduino Uno?
Arduino Uno Pinout The Uno has in total three power pins of which one has a supply voltage of 3.3V and two pins provide 5V.
How many pins Arduino Mega?
54
The Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
What is 5V pin in Arduino?
The “5V” pin is the pin you use to supply power to the Arduino. If you have the Arduino plugged into a USB power source, you can use the “5V” pin to supply 5 Volts to some other devices such as sensors, up to perhaps 450 mA on the basis that the USB can supply up to 500 mA.
Which Arduino pins are PWM?
On Arduino Uno, the PWM pins are 3, 5, 6, 9, 10 and 11. The frequency of PWM signal on pins 5 and 6 will be about 980Hz and on other pins will be 490Hz. The PWM pins are labeled with ~ sign.
How many pins Arduino Nano?
Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms.
How many pins are there in order No?
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.
How many pins does atmega 2560 have?

What is analog pin in Arduino?
Analog pins are general analog input pins, through which analog signal (Max range of 24v) can be feed to the arduino, for further analysis or value reading. PWM pins uses the concept of Pulse Width Modulation.
What is the frequency of the Arduino Uno?
The default frequency of arduino PWM pins is around 490Hz for 9, 10, 3,11 and around 980 HZ for 5, 6, but for many applications we need some higher frequencies. The arduino uno can generate frequencies for PWM pins up to 8Mhz.
What is Arduino Uno?
The Arduino UNO is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc.
