Communication Established

This weekend we worked on establishing communication both between units as well as between chips within each unit. With this, we designed voltage stepdowns as well as stepups to have 3.3V chips (Xbees) communicate with 5V chips (the Arduino).

Naturally, we tested them by sending the string “Hello world” over and over from one to the other, which projected the results on screen.

Success. We also got it to send the output of an A/D converter, allowing sensor readings to be sent. Next up will be connecting to our screen and writing a call and response pattern for the module.
