On Sunday 19th December 2010, there was the fourth seminar on the ARDUINO open source electronic platform in the same place where the previous one was also held.

In the presentation of the fourth seminar, we studied cases of use of wireless communication with ARDUINO. Initially, we discussed the basics and the theoretical aspects of wireless communication, the advantages and disadvantages in radio and infrared communication.

Also, we studied use cases at both hardware (circuit and description) and software (we studied ARDUINO applications at the source code) for radio, infrared, bluetooth, RFID, GPRS, Wi-Fi and GPS. For these cases we used commercial material which we can find on the market (mainly foreign) at any time.

Finally, for each of the use cases, we presented relevant pictures for a better understanding of the circuit of the application.

Happy Hacking!
