Hi All,
I got all the programming done on my project and I'm using the SOUND command to directly drive a piezo speaker. My chip is running of a 3.3 voltage regulator and I can't change that due to one of the sensors which serves as input. I do have 12V available upstream of the 3.3 regulator.
If anyone knew of a way for me to take the output from the chip and amplify that using the 12V to get more volume from the piezo speaker I would greatly appreciate the help.
Thanks,
Brad
