This instructable will focus more on the coding and wiring than on the building. Since the doll you use for this project will play a major role in how you mount and house the components and the doll you use most likely will not be the same one I used, the exact way I mounted the components may not work for you.
Step 1: Main materials
NOTE: I origianlly tried to do this with an Arduino Uno but the code wouldn't work for the newer version. You also have to use the arduino 18 software to compile and load the code
2. Bread board for test wiring
3. universal blank circuit board
4. servo, this one is a pan/tilt
5. wireless Kama nunchuk
NOTE: I know that this code works for this brand of wireless chuk. I cannot say for sure if other brands will work. The code I used was based on code written specifically for this brand of chuk.
6. Nunchuk extender cable
NOTE: This is what i used to connect the nunchuk to the Arduino, there are adapters you can buy that will get the job done as well. I'm not sure if all the wiring will be the same though
7. soldering Iron and solder
NOTE: I got mine from Hobby Lobby, the limbs and head are plastic and the body is cloth
9. power switch
10. momentary switch use for reset
11. small cardboard box to house Arduino and circuit board
12. 3" PVC pipe cut to fit in doll
13. battery, this one is 7.2 Volts
NOTE: not necessary, used to hold extra components and the nunchuk
15. small speaker
NOTE: used with the wireless microphone to provide a way to make the doll "talk"
16. wireless microphone
17. wall wort
NOTE: needed to cut off the end to attach to the battery to be able to power the arduino with it, must be center positive
18. RC 7.2V battery connector repair kit
NOTE: used to connect to the battery so that we can splice this cable instead of the actual battery cable
19. wire for soldering to circuit board
20. various tools including screw driver, screws, drill, small saw, wrie cutters, wire strippers, electrical tape, bracket, wire, needle nose pliers. etc.
21. needle, thread, scissors, cloth (I used an old pillow case)
22. length of chain, length of material that looks like back pack straps
NOTE: optional to make back pack and add chains to pants
