Connecting the HW
Ones the material is acquired, the first step is to connect all the electronic components as in the following scheme, paying special attention to pins (10,11,12,13) of Wifly Shield that are connected to pins (53,50,51,52) of Arduino MEGA. This happens because the SPI signals SCK, MISO, MOSI and SS located in pins 13, 12, 11 and 10 on the Arduino Uno, are moved to pins 52, 50, 51 and 53 on the Arduino MEGA.
The schematics of the project have been allocated in the official Fritzing web site. Follow this link to know how to create your own Green Social Device by using simple components and Arduino.
Once all the components are connected, the next step is to join the electronic part in the vase. For that, it is necessary to make two holes in the vase, one according to the size of the screen, and the other to insert the wires to connect the vase to the mains. Finally, it is necessary to join the LED light and it wires to the artificial daisies to achieve the objective of switching on the flowers depending on whether there are unread mails. This LED lights are connected to pins 40, 41, 42 and 43 of Arduino Mega, but you can choose where you want to connect them.
