I’m considering purchasing the wav trigger to add sounds to a pinball machine. My game activates a buzzer when it hits a specific score. would it be as simple as removing the 2 wires from the buzzer mechanism and attaching them to the wav trigger with SD card and hooked up to speakers? The buzzer has is 6v. Any help appreciated!
There’s a good chance your pinball machine buzzer is AC powered and that would damage the wav trigger.
I’d recommend connecting the buzzer wires to a relay and then connect the normally open and common relay contacts to the wav trigger.
That will isolate the pinball machines electrical system from the wav triggers electrical system and prevent any possible damage.
You could even connect other parts of the pinball machine to the wav trigger in the same manner to produce other sound effects or even background music.
Thanks - I’m definitely an electrical novice. Would adding the relay between the wav trigger and buzzer wires change the voltage from AC to DC? Is there an easy way to tell if the buzzer is AC or DC using a multimeter?
With a little digging I just discovered that it is 6v ac to the buzzer. I see there are a few relays on the sparkfun site. Can you point me in the right direction?
I don’t think sparkfun has any relays that will work with 6 volts ac, you might check a electronic parts distributor to see what they have.
