piezo vs normal speaker
June 11, 2013
i need to know please if the piezo speaker might damage the arduino if connected directly to it like the normal speaker ?
i have read on some forums that a speaker will damage the arduino same as dc motor so i need to know if the piezo speaker will damaged it 2 ?
if yes, then why on the website of arduino the example of tone they connected it to resistor and directly to arduino without using a transister ? (check the link below )
can i use a normal 8ohm speaker instead of the piezo ?
and thanks in advance for all the replies
