ATtiny 85 to trigger Canon camera using IR LEDs and laser tripwire

[system]

Yes but you will have to remove the 328 processor from the circuit. You can either force it into reset by connecting a jumper from RESET to GND or you can remove the 328 processor from the board (with the power off).

AHA! Thank you good sir! I could NOT work out why it wasn't working, fantastic! Thank you so much!
