===Remote door bell ===
Based on the previous door bell example, this sounds an alarm in one laptop when an electrical connection is made on another. Open a Turtle Art session for sharing on one laptop

and join that session on another laptop

The turtle's position is used to transmit the measured resistance to the second laptop.

In this case, the sending laptop is called 'tony'. To select its turtle, by its name, 'tony', plug a text block into the 'turtle' block rather than the normal number block. Load the Python block with the sine wave sample code [[File:Pythoncodeblock.jpg|50px]] and it sounds a 1 kHz tone when the received value is less than 3000.

It could be used to sound a remote alarm on a tank level etc.
