The Arduino Fio is a microcontroller board based on the ATmega328P and runs at 3.3V and 8 MHz. An XRF/ARF/XBee socket is available on the bottom of the board.
The task is to use an old Franzis Duemilanove Clone, a DHT22 and a Ciseco XRF to deliver LLAP (or the Language of the Internet of Things) via Radio (868 MHz) and to display Temperature and Humidity on the LCD.
The old Franzis Arduino Duemilanove came from one of their first starter learning kits. These kits were also sold in the UK at Maplin stores.
The Arduino Duemilanove (“2009”) was a microcontroller board based on the ATmega168 or ATmega328. It had a 14 digital input/output pins , 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
Here we will combine an Arduino Nano, a DHT22 and a Ciseco XRF to deliver LLAP (or the Language of the Internet of Things) via Radio (868 MHz).
The Ciseco XRF is a wireless node. It is low powered and XBee shaped and has a RF serial data module. Operates in the ISM bands (868 to 915 MHz). It can be programmed over the air with a SRF – USB Stick or a Voyager+, as well as directly to the board’s serial or SPI pins with an FTDI breakout board.
The RFu – 328/SRF is an Arduino compatible wireless node.It’s equipped with a 16Mhz Atmel ATMega 328P preloaded with the Arduino Uno bootloader. It can be programmed over the air as well as directly to the board’s serial or SPI pins with an FTDI breakout board.
