Halloween is nearly upon us, but there is still time to build a project that is sure to scare more candy / sweets from members of the public!
In this project we shall turn a simple Poundland (UK Dollar Store type shop) plastic chainsaw, which is a simple plastic hollow prop with no electronics into a roaring sound effect chainsaw! Press the trigger and listen to the sound of a real chainsaw but we remain perfectly safe as there is no moving chainsaw blade.
We shall be using Adafruit’s Circuit Playground Express, which we shall shorten to CPX in this tutorial. But why are we using this board? Well because it is awesome, and it can play audio WAV (Wave) files via the built in speaker…or to an external speaker, but we need an amplifier!
HAPPY HALLOWEEN! Every day this month we’ll be bringing you ideas and projects for an Electronic Halloween! Expect wearables, hacks & mods, costumes and more here on the Adafruit blog! Working on a project for Halloween this year? Share it with us on Google+, in the comments below, the Adafruit forums, Facebook, Discord, Instagram or Twitter— we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). You can also send us a blog tip! Tune in to our live shows, 3D hangouts with Noe and Pedro and Ask an Engineer, featuring store discount codes, ideas for projects, costumes, decorations, and more!
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.
