Screaming Ghost

This is a model I created to use the electronics provided in the Alien3D UFO box for October.

It is inspired (heavily) by King Boo from the Super Mario series.

For this projects electronics you will need are: (links below are affiliate links)

• 1 - PIR HC SR501 - PIR sensor
  • https://amzn.to/3aWU45O
• 1 - Dfplayer - sd card mp3 player
  • https://amzn.to/3aZweX7
• 1 - Arduino Nano (any small Arduino should work)
  • https://amzn.to/3B36FiC
• 1 - 8 ohm 2W speaker
  • https://amzn.to/3G7G3Rd
• 1 - On/Off Rocker Switch
  • https://amzn.to/3vGWu28
• 1 - Battery/ Power source (in the kit was included a 3AA battery pack)

The circuit and code is very simple for this project. When the PIR sensor detects movement it sends a signal to the Arduino, which in turns sends a signal to the mp3 player to play a sound.

Upload the included code to your Arduino and wire up like shown below.

For the assembly of the print please glue the connectors into the back and that should allow a snap fit to the front once dry. You will also need to hot glue the speaker and pir sensor into place.

Please each of the circuit boards into their place into the board holder and that can then be pressed inside the front piece.

For the SD card you will want to format as Fat32 and make a folder named mp3 on the root of the drive. Then in that folder place the sounds you would like it to play. They need to be named 0001.mp3, 0002.mp3, etc. It will play them one by one.
