This library is crucial when working with 1Sheeld board, as it is the interface to your smartphone's accessories, sensors and virtual shields. It allows you to communicate and interact with our mobile app using our own custom protocol.

Make sure you have the latest version of Arduino IDE.

Automatic Method (Recommended)

Open the Arduino IDE, go to Sketch > Include Library > Manage Libraries.

And then, search for our library in the list, pick the latest version and click install.

Manual Method

Download the latest version of the library either from our website or the releases page. Unzip it in a new directory named OneSheeld inside your Arduino's libraries directory.

• Add #include <OneSheeld.h> statement at the top of your sketch.
• Call OneSheeld.begin(); in your setup().
• You are now ready to call any of our shields methods.

Note: To reduce the library compiled size and limit its memory usage, you can specify which shields you want to include in your sketch by defining CUSTOM_SETTINGS and the shields respective INCLUDE_ define. Review any of our examples to see that in action.

We have more than 60+ examples that covers shields usage. They are categorized into two categories according to their complexity.

After library installation you can fire up any of our examples by going to File > Examples > OneSheeld > Advanced / Simple then pick your example.

Here is a an example that capture a photo using your smartphone's camera and post it to Twitter when a hardware button is pressed.

/* Include 1Sheeld library. */
#include <OneSheeld.h>

/* A name for the button on pin 12. */
int buttonPin = 12;
/* A name for the LED on pin 13. */
int ledPin = 13;

void setup()
{
  /* Start communication. */
  OneSheeld.begin();
  /* Set the button pin as input. */
  pinMode(buttonPin,INPUT);
  /* Set the LED pin as output. */
  pinMode(ledPin,OUTPUT);
}

void loop()
{
  /* Always check the button state. */
  if(digitalRead(buttonPin) == HIGH)
  {
    /* Turn on the LED. */
    digitalWrite(ledPin,HIGH);
    /* Turn on the camera flash. */
    Camera.setFlash(ON);
    /* Take the picture. */
    Camera.rearCapture();
    /* Wait for 10 seconds. */
    OneSheeld.delay(10000);
    /* Post the picture on Twitter. */
    Twitter.tweetLastPicture("Posted by @1Sheeld");
  }
  else
  {
    /* Turn off the LED. */
    digitalWrite(ledPin,LOW);
  }
    
}
