Here is my first project using Raspberry Pi.
It's an animatronic Halloween Electric Chair Prop using Raspberry PI GPIO.

The PI and software: (what I learned to do with the PI on this project)
- written in Python using IDE
- opens and plays an MP3 file
- configures GPIO
- opens a .csv text file with ones and zeros and outputs to the GPIO port at a regular interval (every 33 msec)
- reads an input on the GPIO to trigger the prop
- auto executes the program at bootup
The sequence is 1 minute long
- waits for the switch to ground an input pin
- hits a relay to turn on a flood light and a turn on a yellow beacon light on top of the electric panel
- the side lights flash in sequence with a buzzer warning sound for 10 seconds
- the electric noise starts and he starts to shake (there's a hedge shaker toy in his head)
- he starts to scream and pneumatics start jolting him forward
- the electric noise gets louder and he jerks forward and back more violently
- the strobe light starts flashing in the electric panel
- the sequence ends as a fog machine pipes fog through his head
