I posted a question earlier regarding the DR4018 not being able to operate a tiny LED with built in flasher, it operates a normal LED with no problems. The recommendation was to use a small relay switched by the DR4018 to operate the. LED,s.
I now have a small 5V relay with a series resistor to drop the DR4018 down from a measured 10V DC at the output terminal, the relay operates OK but with a continuous buzz.
I assume the output from the device is DC so why the buzz and can I stop it?
