Is there a tutorial or Topic on how to tweet form your core when motion is detected? or just to receive a notification when motion is detected by the core through a motion detector?

Okay guys, this code by SaraJo works perfectly. The instructions are pretty simple. Go to this site and follow Step 1 . Save the long string you get (OAuth Key), you’ll need this later! Paste the code I’ve provided below into a new Sketch in the WebIDE. At the top of the code you’ll see a line cal…

Thanks @timb ! Worked first time :smile:

Awesome! I’m glad everything made sense. I’ll go ahead and wrap that code into a little function so you can call it from anywhere in your sketch! I’ll add some protection so you can only post once every 60 seconds (if you try to do it more often the function will return an error).

Although… Having said that I’ve just tried to run the same code again (well over a minute later) and this time it’s not working. On reading the “ arduino-tweet.appspot.com ” page it says “Twitter seems to reject repeated tweets with the same contenet (returns error 403).” So I ran the code again an…

Won’t a Delay (total miliseconds) in the code work?

I think it’s important to know that Twitter is really protective of its resources and api. If you hit their servers too quickly, or tweet the same thing over and over, they’ll send you ‘back off’ http error codes, and eventually if you keep tweeting too aggressively you could get banned from tweeti…

I’m just trying to get a PIR sensor to tweet when it goes off. Which is hopefully never as that would mean someone is in my house without my say so. But if you can’t tweet the same message (eg “Movement Detected”) more than once then how do you get it to reset so it can send another tweet at a late…

Ah, totally, in that case a date or time stamp makes perfect sense. You could use the NTP and Time.h examples to grab a current timestamp.

Or use my SparkTime library Here’s the general idea: UDP UDPClient; SparkTime rtc; unsigned long currentTime; unsigned long lastTime = 0UL; String tweetStr; char msg[128]; void setup() { rtc.begin(&UDPClient, "north-america.pool.ntp.org"); rtc.setTimeZone(-5); // gmt offset } void loop(…
