Good morning everyone,
I am working on my Halloween Prop, it is a zombie with a rotating head, I've installed a servo on it, so now I want to be able to move the head as someone stands in front of it. I was thinking on using the EZ1 Ultrasonic sensor, I have only 1, so I was planning to buy another one and use 2 of them to triangulate the position of the person on front and then with a simple algorithm move the head towards where the person is standing. Does it sound like a good idea or there is something simpler to accomplish the same goal?
Thank you in advance.
