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.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
