Hacking the IKEA FREKVENS LED panel with a microcontroller #Feather #Arduino @IKEA
The IKEA FREKVENS is a sound sensitive light panel that’s attracted the hacking community to repurpose for a number of cool projects. GitHub user frumperino has started an Arduino library to allow control of the FREKVENS using a 3.3 volt microcontroller like the low cost Adafruit Feather M0 Basic (Adafruit and Digi-Key).
Instructions on wiring changes are provided (soldering is required). The microcontroller must be a 3.3 volt logic level unit, according to the post: “If you want to try hooking this up through 8-bit 5V AVR antiques like an Arduino Uno, then you must use level shifters.”
The code is used with the open source software Adafruit GFX library, programmed in the Arduino IDE.
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.
