Hi Nigel,
I am in charge of the programming the chip and designing the pic cct board. It is going to work on a door sensor. The idea is that the head will react every 5th time that the door opens and will say one of four prerecorded messages.
Basically I mainly need some commands. I am planning on using pulse width modulation to control the servo. The speech chip is an ISD 2560.
I am attempting just to get the moving parts to go up and down when the speech is activated. Its not supposed to be a rocket science project, but I am up to my nuts!!
