I have this paper robot and I want it to look fancy by adding an LED on his head. Hihi. So I decided to make this antenna and adding a sound to it using Raspberry Pi.
This is the video for this project.
|Speaker||Raspberry Pi : Audio Jack|
|Red LED (+)||Raspberry Pi : GPIO 17|
|Red LED (-)||Raspberry Pi: GND with Resistor|
This project is using Scratch 2.0 with GPIO support.
This is the sample code used for this tutorial. Try it!
