HELP for using SPDT relay to turn on toy Answered
I'm new to physical computing and have a question that's probably very easy and yet I can't figure it out. I have a doll that cries or laughs depending on which connection you make (if you press the left side it cries, right side it laughs). I want to hook it into a bread board and then control when it cries or laughs with arduino. My teacher said I need to do this using a relay (its the big black one, I believe it is a SPDT). He gave me the schematic that I've attached here.
From what I know the relay has 8 pins. according to this sketch I need to connect the 2 pins furthest away (nothing near them) to a diode and 5Volts. But- what about those other 6 pins? What do they attach to? Any help would be great!
