RF Module comprises of a transmitter and a receiver that operate at a radio frequency range. RF Module is a cheap wireless communication module for low cost application. In this project, two Arduino boards will communicate using wireless communication. 434 MHz Receiver Module (or 315 MHz Module)Īrduino UNO is the low cost, open source, microcontroller board for electronics prototyping.434 MHz Transmitter Module (or 315 MHz Module).Arduino UNO (or any other Arduino board).

The circuit for the Transmitter part of the project is shown below.Īnd the circuit for the Receiver part of the project is shown below. The WiFi library is very similar to the Ethernet library, and many of the function calls are the same.įor additional information on the WiFi shield, see the Getting Started page and the WiFi shield hardware page.As it is a wireless communication project, the circuit consists of a Transmitter part and a Receiver part. Digital pin 7 is used as a handshake pin between the Wifi shield and the Arduino, and should not be used. On the Mega, the hardware SS pin, 53, is not used but it must be kept as an output or the SPI interface won’t work. This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. Also note, if the SSID is not broadcast, the shield cannot connect.Īrduino communicates with the WiFi shield using the SPI bus. The library supports WEP and WPA2 Personal encryption, but not WPA2 Enterprise. It can serve as either a server accepting incoming connections or a client making outgoing ones. With the Arduino WiFi Shield, this library allows an Arduino board to connect to the internet. You are recommended to install this update per these instructions

The firmware for the WiFi shield has changed in Arduino IDE 1.0.5.
