Saving pictures to Dropbox

Finally, we are going to make our first application using the hardware that we built. There will be two parts here: an Arduino sketch and a Python script. The Arduino sketch will be in charge of taking a picture in case motion is detected and call the Python script. The Python script will actually upload the pictures to Temboo every time it is called by the Arduino sketch.

This is the complete Arduino sketch:

// Sketch to upload pictures to Dropbox when motion is detected
#include <Bridge.h>
#include <Process.h>

// Picture process
Process picture;

// Filename
String filename;

// Pin
int pir_pin = 8;

// Path
String path = "/mnt/sda1/";

void setup() {
 
  // Bridge
  Bridge.begin();
 
  // Set pin mode
  pinMode(pir_pin,INPUT);
}

void loop(void)
{
 
  if (digitalRead(pir_pin) == true) {
   
    // Generate filename with timestamp
    filename = "";
    picture.runShellCommand("date +%s");
    while(picture.running());

    while (picture.available...
