I'm an illustration student planning on making a very slightly animatronic silicone doll for my degree show. Now, I thought I had enough time to teach myself enough Arduino to accomplish what I set out to do, but it's now 17 days until hand ins and because of some technical and post-office related hitches with my moulding process I haven't got round to writing the program for the animatronics.
What I originally wanted to do was have a head up/down mechanism, eyes l/r, up/down and ears forward and back but I quickly realised this was unrealistic (and expensive) and I quickly reduced it down to the eyes simply moving left, right, up and down. Here was my hardware layout for the eye movement, based on one of WilletFX's designs.
I have made the rig and tested it with a servo sweep - it works well! It's just my basic, basic
knowledge of arduino hardware means I am constantly terrified I might explode my servos because I didn't put in the right resistor or something. It takes me a lot of brain power to get my head around engineering and right now I'm focussing it all on getting my portfolio polished, blah blah...
I do however know how to connect up one
servo, so I've reduced the movement yet again to just... left and right. (I got a strange mini breadboard with my starter kit and I'm not sure how it works :S) What I've come here to ask is if anyone would be willing to write a few short and simple lines of code to move the servo randomly (and slowly) to mimic eye movement. I can do the wiring for this one, messily but well enough for the exhibition.
If anyone wants to tackle two servos and try and help me set up the wiring I would be forever appreciative. I have a lot of electrical gubbins I bought for the project but no brain behind it really! I know this is a lot to ask because it would be so much simpler in real life but I learn quickly and I am willing and able to accept any advice or abuse you have for me!
I did write some code which was working well enough but it's on my laptop locked up in uni at the moment so I can't show it. It was a modified version of the sweep program, very basic and probably stupid.
Also, as an art student I would be more than happy to pay you in the form of what I do best, making art dolls... It's not much of an incentive but it's there if you want it. (You can see some on my website, magweno.com) I will also credit your incredibly helpful contribution at the degree show (with your consent of course).
Any help, any help at all, is incredibly appreciated.
