The Arduino Project

Example of a simple Arduino program.

What can we connect on the digital pins of Arduino?

The digital inputs and outputs (digital I/O) on the Arduino are what allow you to connect the Arduino sensors, actuators, and other ICs. Learning how to use them will allow you to use the Arduino to do some really useful things, such as reading switch inputs, lighting indicators, and controlling relay outputs.

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

Parts of the Arduino board

Arduino UNO is a microcontroller board based on the ATmega328P. 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 versions of the Arduino board are there?

Arduino Uno (R3) Arduino Nano. Arduino Micro. Arduino Due. LilyPad Arduino Board. Arduino Bluetooth. Arduino Diecimila. RedBoard Arduino Board.

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. Whatever we write inside these curly brasses will run again and again. Its start with curly { } opening bracket & close with closing brackets.

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. One example is when you want to turn your robot on — that does not happen multiple times! In void loop(), your code will repeat over and over again.

What programming language does the Arduino use?

C++ programming language

What are the Arduino digital pins?

The pins 4, 6, 8, 9, 10, and 12 are used as a digital input or output for the Arduino board. Serial Pins: This pin is also known as a UART pin. It is used for communication between the Arduino board and a computer or other devices.

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, the analog pins also have all the functionality of general purpose input/output (GPIO) pins (the same as digital pins 0 - 13).

What is the Arduino project?

Arduino is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
