Make A Motion Activated Musical Wreath With Arduino
Make a motion activated wreath with Arduino and MP3 player. via instructables
This wreath uses an Arduino microcontroller with the Adafruit MP3 shield and a Parallax PIR motion sensor to detect if someone is approaching the doorway. It then plays a custom greeting pre-recorded and pitched to sound like an Elf, after which it plays a random Christmas Song. The song(s) will keep playing as long as the PIR sensor picks up motion within 15 seconds.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
