I would like to add a buzzer to my RA for acoustic alerts. I'm from europe, so ordering a buzzer is not really an option (40$ for shipping). Can anybody give me some specs about a buzzer that would work with the RA?
I have already tried some buzzers on the ATO ports, but could only hear a very very silent tone.
I used a code like this:
Code: Select all
pinMode(lowATOPin,OUTPUT);
digitalWrite(lowATOPin,HIGH);
Connect this buzzer to any available standard or boosted port.
what port is usually intended to be used for a buzzer and what code is needed to activate it?
cheers,
Christian
