I've been passively thinking about Arduino projects for awhile, and I've come across an interesting application during the course of my work.
Essentially a range finder on a servo. I've found many similar projects by searching, so my only remaining technical question is regarding the range finder.
I've found short range solutions, and long range professional solutions (wow, expensive), but nothing in the 40'/12m range. The AL_01 from lightware.co.za
was the most feasible solution that I found, but the range is twice what I would need for this application, and kits don't appear to be available for purchase.
Anyone come across a range finding method for up to 40ft that won't cripple my bank account?
ps: ideally for use in sunlight, but ambient light can be controlled if otherwise impossible.
