Sucess!!

WEll i'll start off with i'm lazy. that being said nothing is more exciting then doing soemthing right when i finally try. This afternoon i hooked up an old pc speaker i salvaged from work.

 

The good news: it works, and generates tones based on input from my ir sensor.

 the bad news: its awfully quiet, i would think it has to do with being a pc speaker and being driven by 5v- whatever the darlington takes out of it.

 

now the decision: do i hook up a second power supply?  or search for a speaker ment to be driven off of 5v?
