Pumpkins are usually seen as Halloween decoration, but in this project,we took it one step further away, this jack-o’-lantern responds to various external stimuli.
When the lights of the room are switched off, the pumpkin rotates 90 degrees, facing the user. If the sound sensor registers loud noises, it turns the pumpkin eyes red, using three LEDs on each eye.
This is a better version of a classic Halloween decoration.”
