At this point, you are almost finished. However, before packaging I suggest that you make a preliminary test on your system.
First, connect the Arduino to the PC and upload my sketch, that you can download from here
. You'll probably need to upload the following libraries from the Arduino website
- Ethernet (for the Ethernet Shield)
- EthernetDHCP (for self-configuring the IP address is you use DHCP at home)
- LiquidDisplay (for the LCD)
- TextFinder (for parsing the RSS feed)
Second, after disconnecting the PC, connect the Ethernet Shield to the home router via Ethernet cable and then power Arduino.
Third, you may need to wait some time to see the tweet (the sketch is programmed to read my own last tweet, if you didn't modify it). If it gives a connection error, try pushing the reset button on the Ethernet Shield to refresh the network configuration.
On the LCD, you should get the title "Twitter2LCD" and then after some time (around 1 minute) the tweet divided into two pages. It'll continue updating every minute or so if you leave it on.
If everything worked correctly, you can proceeding to the final setup and packaging steps. Otherwise, get back to step 1 and test connections and correct behaviour using samples on the Arduino website
