Canon 450D Remote Control

Finally,
After a lot of work (remember, I'm a beginner), a few burned parts and also a pcb I've got this circuit working...I know that is room for improvement so i wait yours suggestions.

I want to THANK BrownOut, mneary and Audioguru (from /www.edaboard.com) for the help he provided to me

From tomorrow i will start to test it on my camera to see what are the results.


Thanks again and i will wait yours suggestions

Nice. Making a remote for my old 300D with timer and light trigger was one of my first microcontroller projects.

I'm still not satisfied with the sensitivity of the circuit
Can anyone suggest me how to increase it?
I need to trigger at the sound of a water drop in a glass

What is this used for?

is a trigger for a dslr camera
