Andy, I had already made a arduino ir intervalometer for my nikon d50 and the first thing i wanted to be able to do was make field adjustments without having to use a laptop, i was thinking of using some dip switches to set the times and then found your project, so i ordered a lcd unit which arrived today and about 10 minutes later i had it working and taking photos.
so great work, it works and seeing as you were looking for feedback, i thought I would throw you some ideas.
- is theere a way to turn off the lcd backlight, until there is a button press (to save power when running on batteries)
- could you add a menu to select from a range of different cameras IR command structures (say f you want to change from a nikon to Canon camera)
3, I also made a shield to take a photo when lightining is detected and was wondering if that would be an idea to include as well.
