Will show several ways to show how to use an Arduino as a sensor using The Nexus 7 for a terminal and to do development. This can be very important for protecting your electronic equipment especially servers.
Note 1: All connections are to a standard Arduino board. This instructable is for users very familiar with the Arduino boards. If you are a novice, you may want to get additional help.
Note 2: With android 5.1, you may not be able to direct connect the devices, but using a router that has a dhcp server can be a temporary fix. Android 5.0x does not seem to support ethernet connections.
Wigh android 5.1.1and the latest version of the software, there is no way to fix the baud rate so uploads do not work.
