SainSmart LCD Keypad Shield for Arduino with Franzis Duemilanove Clone, DHT22 and Wireless Things XRF

Temperature and Humidity on SainSmart LCD

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.
