• DFPlayer Mini x1

This tutorial here is just to show you how to connect this player module with Arduino and speaker and the Arduino sketch provided here just to play a few sample sounds I collected from the Internet.
With all the lights and decorations that people use at Christmas, power is left on all the time, and electricity bills skyrocket. I made this motion-detecting Christmas tree light setup that only turns on when people are nearby.
Hardware list:
PIR Sensor x1
Bluno x1
I/O Expansion Shield v7.1 x1
LED Strip x1
Relay Switch x1
Mini mp3 module
DFSpeaker v1.0
Regular power extension lead (with some modifications)
1k resistors x2

Project 3. How to Make a Jumping Paper Frog
Back in the 80’s and 90’s kids made their own toys like paper planes and spinning tops. These toys accompanied them throughout their childhood. Now let's make a frog.
1. Bluno Beetle controller
2. 3.7V Battery
3. Analog Sound Sensor ( compatible with Arduino)
4. Player module

Project 4. Death Star word clock

Fast forward to Maker Faire 2015, where I had the pleasure of meeting the Particle team and several of the Elites, I noticed one of the latter was building a word clock as well. That's what gave me the final motivation to build one myself. Luckily I saw him struggling with soldering well over 100 Neopixels for over a day, and I decided mine would have to be simpler. One of the other Elites had made an interesting project with an RGB matrix, which sparked the idea that those two might make a great combo.

• Particle Photon × 1
• DFRobot DFMini player MP3 × 1
• neopixel × 1
• 32x32 RGB LED matrix 6mm pitch × 1
• RGB matrix shield × 1
