Developing with Arduino C

Arduino consists of a microcontroller board and the Arduino IDE used to program it. The Arduino board comes in various models, including the Arduino Uno, the Arduino Mega, and the Arduino Nano.

The programming language used for Arduino is a version of C. The typical Arduino workflow is shown in the following architectural diagram:

As you can see, a PC is used to write programs that are then compiled and sent to the Arduino board. The following is a typical Arduino program. This example flashes an LED:

void setup() {  pinMode(LED_BUILTIN, OUTPUT);}void loop() {  digitalWrite(LED_BUILTIN, HIGH);  delay(1000); digitalWrite(LED_BUILTIN, ...
