Communication / RS-232:

» RS-232 01: Send Data

This sketch shows how to send data through RS2-32 standard. This standard defines the electrical characteristics of drivers and receivers for use in digital systems. It does not specify or recommend any communications protocol.

Required Materials

1 x Waspmote
1 x battery
1 x RS-232

Notes

If you are using the socket 0 for communication, for viewing data in the serial monitor, you should open the USB at the same speed.
