The Idea
Create an Arduino Sketch to Tweet (via the Arduino Twitter Library) the current number of inquiries every time a push button is triggered.
Getting Started
Check out Getting Started with an Arduino Ethernet Board if you’re in trouble with the pre-settings.
Hardware Settings
As mentioned above we’ll need an Arduino with Ethernet connection to publish our Tweets on the web. Therefore a simple push button is used to trigger the event.
Connection Scheme & Breadboard
Software Settings
Required Arduino Libraries
At this point we’ll need some additional libraries. Download the Twitter Library and add it to your libraries folder within your Arduino IDE (Mac: Documents › Arduino › libraries or respectively on Windows: My Documents › Arduino › libraries).
After that import (Arduino › Sketch › Import Library…) the following libraries to your current sketch: SPI, Ethernet, Twitter.
– Download : Twitter.h
– Reference : Ethernet. h
– Reference : SPI.h
Authorize App via OAuth Token
Using the Tweet Library to post messages to Twitter from an Arduino we’ll need to get access via a token: Get Your OAuth Token
FYI: You can revoke access at all times within your Twitter Apps Settings
Keep calm and code on
Take a look at the included examples of the Twitter Library you’ve downloaded above.
Insert your Twitter OAuth Token and your Ethernet IP address and give it a try!
