This tweeting RFID reader is a great working example for the mbed. When an RFID tag is read it is matched with the name of the owner and a Twitter message is sent out. This is very similar to the RFID cat tracker that used an Arduino.
The code is short and simple due to the use of*available*mbed libraries. The hardware needs just two extra modules, an RFID reader and an Ethernet socket.*If you’re trying to decide if you can make the jump over to ARM development this certainly presents an easy learning curve and an opportunity to get*comfortable*with the code and the libraries before you make a purchase. It’s also a great set of test code to start with if you have an mbed and the two supplementary modules on hand. The quick video clip after the break will walk you through the components and the code.
