<h3 >Arduino GoPRO libraries</h3>This tutorial relies on the use of the <a href="https://github.com/agdl/GoPRO">Arduino GoPRO libray</a> that can be installed using the <a href="https://www.arduino.cc/en/Guide/Libraries#toc3">Arduino Library Manager</a>.This library allows the user to fully communicate with a GoPRO camera, but we will use only two very basic functions:<ul ><li >Turn ON and OFF the camera;</li><li >Start or stop the capture;</li></ul><h3 >How it Works</h3>The libraries relies on the fact that a connection between the camera (in AP mode) and the board exist.The library has so the method <code >GoPRO.begin(ssid, pass)</code> to try a connection. This function in fact returns <code >true</code> if the connection is established <code >false</code> otherwise.The sketch interacts with three buttons:<ul ><li >Connect/Disconnect (attached to A1);</li><li >Turn ON/OFF the camera (attached to A2);</li><li >Start/Stop Capture (attached to A3);</li></ul>Pressing the buttons reflects to the status of the three LEDs in such a way:<ul ><li >Blue LED: when the connect button is pressed, the board tries to establish a connection with the camera. If the connection is successful, the LED will be turned ON. If pressed another time the connection will be stopped and the LED is turned OFF;</li><li >Green LED:when the turn ON/OFF button is pressed, the board sends the <code >turnOn()</code> command if the LED is OFF the <code >turnOff()</code> command otherwise;</li><li >Red LED:when the Start/Stop Capture button is pressed, the board sends the <code >startCapture()</code> command if the LED is OFF the <code >stopCapture() </code>command otherwise;</li></ul>NB: Every command is sent only if the connection between the board and the camera is still active. This can be check using the method <code >checkConnection() </code>that returns true if the connection is active, false otherwise.<code ></code>
