===Using frequency to control outputs=== | |||
[[File:Freq-sensor-ic.jpg]] | |||
Turtle Art is programmed to produce two different frequency sounds. The headphone output of the XO is connected to a pair of [http://www.datasheetcatalog.org/datasheet/nationalsemiconductor/DS006975.PDF LM567] tone decoders, each of which lights a LED when its input signal frequency is present. With this principle we could control any device based on the frequency emitted by the XO. | |||
