The Little Bird Uno R3, is a 100% Arduino™ compatible development board.

Just like the original Arduino Uno the Arduino Shield compatible design makes adding expansion boards easy.

This Arduino can be powered from 7-12 VDC or using your computer's USB port (limited available current to pins if done so).

This board includes a USB type B Cable.

We have written so many tutorials for the Arduino here!

Jargon buster

Plain-language definitions for the technical terms used above.

Shield
An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.

Code Examples

Sample code to get started with this product

blink.ino
Arduino

The classic Arduino Blink sketch. Turns the built-in LED on for one second, then off for one second, repeatedly.

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno R3
  it is attached to digital pin 13.

  This example code is in the public domain.

*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}
