The ceramic ghost is from a home decoration shop. I have put a little sandwich paper inside, so the LED light can be seen.
The CircuitPython source shows a candle light effect. For the flame, a mystic cyan color is used, so the ghost appears really spooky.
If you copy
.wavfiles to the Circuit Playground, a random sound effect is played from time to time. I found nice free sound effects on soundbible.com that surely give everyone the chills. The sound files should be converted to mono and 16 kHz sampling rate, so they fit into the tiny Playground Express memory. The sound effects can be muted using the switch on the Playground, if they should become too annoying.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
