Need help with accelerometer triggering temboo over wifi

Projects Programming
1

Hello,

I've got a sparkfun 345xl accelerometer connected to an Arduino Yun. The accelerometer detects activity, and then uses temboo + twillo to send an SMS message.

I'm also a complete beginner, and have tried to hash code snippets together from what I've found online, without actually knowing much of what I'm doing.

The code below somewhat works, and I can sense and display activity in the serial monitor. A call is made to Temboo and an SMS is sent successfully. However, this only happens the first time activity is detected. Subsequent times, it detects activity, but then doesn't send out the call to temboo.

What am I doing wrong? Could someone kindly help me learn how to do this correctly? Thank you in advance.

Given that code, how many times do you expect to send an SMS?

Hi Paul,

Thank you very much for responding. I realise the code i copied is set to stop after 2 runs, and delay by 30 seconds.

However I'd like to send an SMS message when activity is detected, and then stay quiet for a period of time, say 5 minutes, before it is able to detect activity again and send me the next SMS.

So:

  1. Activity is triggered.
  2. Send SMS.
  3. Wait 5 min.
  4. Detect fresh activity whenever it happens next.
  5. Send SMS

Hope that makes sense.

This is what happens now:

  1. Power on.
  2. Activity detected.
  3. SMS message sent successfully.
  4. Another SMS message is sent (I can change that by setting max calls to 1)
  5. Serial monitor goes back to "waiting" and ignores any activity for 30 seconds.
  6. I shake the accelerometer again.
  7. Serial monitor shows "activity"
  8. Serial monitor shows "waiting" without actually sending out the SMS.

I can repeat steps 6-8 over and over (with 30 second intervals in between), but the SMS is only sent the first time. I have to power down the board, and then start over to trigger the first SMS to be sent.

Paul,

Thank you for the hint. I fiddled around some more and managed to get it working by removing the calls and max calls section.

Here's the working code:

#include <Bridge.h>
#include <Temboo.h>
#include "TembooAccount.h" // contains Temboo account information, as described below
#include <SparkFun_ADXL345.h>         // SparkFun ADXL345 Library
