Interactive Halloween thunder effects #electronichalloween

Interactive Halloween thunder effects from Brian Enigma:

The device is comprised of two boxes, sep­a­rated across the room and con­nected by a four-conductor tele­phone cable. Next to the entry­way is the “brain” box. This is connected to the LED strip above the garage door. It houses the Arduino and sound gen­er­at­ing hard­ware (Wave Shield). It is also hooked up to a small stereo. On the other side of the room is the “remote con­trol.” This is the box with but­tons for pick­ing a set of ambi­ent light­ing colors as well as the hid­den foot switch.

The tele­phone cable pro­vides power and ground, but also has a “sense” line, hooked up to an analog-to-digital con­verter on the Arduino. Because of the resis­tor matrix in the box, each but­ton will return a dif­fer­ent volt­age back through the sense line. If you have used iPhone or Android head­phones with inte­grated vol­ume and answer but­tons, this is the exact same con­cept but blown out to four but­tons and a foot switch….

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
