Running into a super strange problem. I'm in college and they gave us these little remote control arudino cars to build and program some functions. I'm trying to add a buzzer to it (extra credit lol). I am using the TimerFreeTone Library because I kept running issues with timer1 and timer2.
When I have a sketch that only makes it beep its fine. BUT when I have it running in the car sketch the buzzer is SUPPERRR quiet, like I have to hold it in my ear quiet.
I'm not using any transistors or anything just plugged it into port 0 and gnd. Any ideas?
Certainly have an idea. There are active buzzers and passive buzzers. By the description you have a passive buzzer. It requires the driving voltage to create the sound. The active buzzer has an oscillator built in that makes the signal to make the sound.
If your buzzer is passive you will have to use, perhaps, the tone() function. Do a search on the forum for more info. Or Google.
