Even if the circuit is only drawing about 100mA.
As soon as i plug in the Sharp sensor I get a high pitch sound on the speaker.I'm not sure why this happens but I think I need to separate the audio from the power supply.
The second issue is that my 5v power regulator is getting really hot.Even if the circuit is only drawing about 100mA.
