Hey

I'm made a control unit for my electronics "shop" or shed (for normal people).

But just in case I have missed something could someone please take a look at it. Also the board layout.

On that page one can also find eagle files for both the power supply and control unit (here to be checked). Power supply unit has been checked and works very well ;)


Anyway thanks for your help and time.
I'm open to all suggestions and hints and bugs.

I'm not that familiar with AVRs but is it good practice to drive the speaker directly like that from IC1 pin 13?
T1, the photo transistor, appears to be wired backwards.
 
I am with kchriste. Maybe a small cap inline with the speaker or a peizo. And the T1 looks backwards to me.

the speaker is a VERY small buzzer thingy. It can be driven directly from micro (have done it before). And the transistor is now flipped.
Anything else? On the board maybe or something...
