Arduino with WiFi shieldLED bulbs Red Green BlueThingSpeak API

inspirationUses Twitter’s Search API to measure the world’s mood into several predefined categories.

problemTwitter’s API 1.1 requires OAuth for almost all API requests. This process however takes a lot of memory space in the Arduino’s already limited resources

solutionThingSpeak takes care of the OAuth process as well as monitoring Twitter and storing the data.

applicationmostly, just a fun application

more importantly, however, it is an exhibition of the possibilities opened up by and the ease of using ThingSpeak

extension

create a customized ThingSpeak server (code is open source) which would stream the user’s tweet feed while an Arduino will perform sentiment analysis on the said feed
