xample of a simple Arduino program.

1int buttonState = digitalRead(buttonPin); //read and store the button state (0 or 1)
3if(buttonState == HIGH){ //check if state is high (button is pressed)
4 digitalWrite(LED, HIGH); //turn on LED.
5} else {
6 digitalWrite(LED, LOW); //turn off LED.

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?

Arduino is What Kind of Coding Language? Arduino uses a variant of the C++ programming language. The code is written in C++ with an addition of special methods and functions. Moreover, when you create a 'sketch' (the name given to code files in this language), it is processed and compiled to machine language.

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. 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 can we connect on the digital pins of Arduino.

There are essentially two types of pins, analog and digital pins. Digital pins can be set to either HIGH (usually 5V or 3.3V) or LOW (0V). You can use that to e.g. read a button state or toggle an LED. Important: unfortunately, the MicroPython implementation does not match the regular pinout of your board.

Do some research on the internet:

What is the Arduino project?

. 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 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).
