Arduino

What is the Arduino project?

Arduino is an open-source electronics platform based on easy-to-use hardware and software

What versions of the Arduino board are there.

Arduino Uno (R3)

Arduino Micro.

Arduino Due.

Parts of the arduino board

It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.

What programming language does the Arduino use?

Arduino uses a variant of the C++ programming language. The code is written in C++ with an addition of special methods and functions.

What is the void setup() section used for in Arduino programming?

The code that you put inside void setup() will only run once, and that will be at the beginning of your program.

What can we connect to the analog pins of the Arduino?

A/D converter

What are the analog pins on the Arduino?

While the main function of the analog pins for most Arduino users is to read analog sensors,

What are the Arduino digital pins?

Digital Pins: The pins 4, 6, 8, 9, 10, and 12 are used as a digital input or output for the Arduino board.

What can we connect on the digital pins of Arduino.

You'll use digital pins to read data from some components (sensors) and write data to other components (actuators). A digital pin can have only 2 states: LOW or HIGH.

What is the void loop() section used for in Arduino programming?

The void loop function takes no argument inside it. Code within Void loops functions repeat consecutively until Arduino is turned off.
