\section clock_radio Controlling a radio
|
||||
|
||||
The relay connected to D11 can be used to control the power to a separate
|
||||
radio circuit so that the radio can be used as an alarm. The relay switch
|
||||
should be inserted between the radio's power supply and the main radio circuit.
|
||||
When the relay is off, no power is applied to the radio. If the radio is
|
||||
powered off 5V, then the relay circuit can be altered as follows to power
|
||||
the radio directly from the Arduino's power supply:
