Arduino enthusiasts looking for a project to keep them busy over the next couple of weekends might be interested in a new MIDI-triggered LED cube project. This fascinating project combines a little Arduino hardware and programming to create a visually stunning display.
Check out the video below to learn more about the set of illuminated cubes that have been created using plexiglass boxes combined with LED strips and what looks like an Arduino Uno development board.
The setup consists of an Arduino, some MOSFET for 12V (in the LED cubes), and opto-triac for 220V (for the big lightbulb props). Holograph wrote a MIDI sequence in Ableton Live that syncs with the tunes, assigning every note to a light-up box. The sequence is sent to Arduino, which activates the LEDs as the dancers move through their choreography.
Understanding the Components
The core of this project revolves around the Arduino Uno, a popular microcontroller board known for its versatility and ease of use. The LED cubes are constructed from plexiglass, which provides a sturdy yet transparent housing for the LED strips. These LED strips are controlled by MOSFETs, which are used to handle the 12V power required by the LEDs. For the larger lightbulb props, opto-triacs are employed to manage the 220V power supply safely.
The MIDI sequence, created in Ableton Live, is a crucial part of the project. Ableton Live is a digital audio workstation (DAW) that allows users to compose, produce, and perform music. By writing a MIDI sequence, the creator can synchronize the lighting effects with the music, ensuring that each note triggers a corresponding light in the LED cubes. This synchronization is what makes the project so captivating, as the lights dance in perfect harmony with the music.
Expanding the Project
For those looking to expand on this project, there are several avenues to explore. One option is to incorporate more complex lighting patterns and effects. By experimenting with different MIDI sequences and programming techniques, you can create a more dynamic and engaging light show. Additionally, you could integrate other types of sensors, such as motion detectors or sound sensors, to make the LED cubes react to their environment in real-time.
Another exciting possibility is to use different types of LEDs, such as RGB LEDs, which can produce a wide range of colors. By programming the Arduino to control the color and intensity of the LEDs, you can create a more vibrant and visually appealing display. This could be particularly effective for performances or installations where the lighting needs to change to match the mood or theme of the event.
