The Arduino Uno R3 is programmed using the Arduino IDE (Integrated Development Environment). The board features a builtin USBto-serial converter, allowing you to upload code directly via USB cable.
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}
The above example blinks the built-in LED – the "Hello World" of Arduino programming.
The Arduino Uno R3 features 6 analog inputs, 14 digital I/O pins (6 with PWM capability), and a 16 MHz crystal oscillator. The board includes everything needed to support the microcontroller: simply connect it to a computer with a USB cable or power it with an ACtoDC adapter or battery to get started.
ATmega328P microcontroller delivers reliable performance with 32KB flash memory, 2KB SRAM, and 1KB EEPROM – enough for most projects.
√ Perfect for beginners, students, and professionals
√ Ideal for STEM education and prototyping
√ Backed by a global community of makers and developers
