What is Hardwareserial?
A hardware serial, as the name suggests, denotes that a dedicated piece of hardware (UART) enables Serial communication. In Arduino Uno, for instance, pins 0 and 1 have UART support,and they are connected to the USB via a USB-to-UART converter.
What is software serial?
The SoftwareSerial library allows serial communication on other digital pins of an Arduino board, using software to replicate the functionality (hence the name “SoftwareSerial”). It is possible to have multiple software serial ports with speeds up to 115200 bps.
What is UART in Arduino?
UART stands for Universal Asynchronous Reception and Transmission and is a simple communication protocol that allows the Arduino to communicate with serial devices. The UART system communicates with digital pin 0 (RX), digital pin 1 (TX), and with another computer via the USB port.
Is Arduino an open source?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online.
What is a UART used for?
A UART is usually an individual (or part of an) integrated circuit (IC) used for serial communications over a computer or peripheral device serial port. One or more UART peripherals are commonly integrated in microcontroller chips. Specialised UARTs are used for automobiles, smart cards and SIMs.
Is Arduino SPI or I2C?
Introduction to SPI on Arduino. SPI, which stands for the serial peripheral interface, is similar to I2C where it is a different form of serial-communications protocol specially designed for microcontrollers to connect. SPI operates at full-duplex where data can be sent and received simultaneously.
What OS does Arduino use?

What is PWM in Arduino?
PWM stands for Pulse Width Modulation and it is a technique used in controlling the brightness of LED, speed control of DC motor, controlling a servo motor or where you have to get analog output with digital means.
