The L.U.D.S. adds a vibration sensitive LED array within the drums to make every beat the drummer
strikes, enhancing drumming performances. Additionally, the system has a visual metronome
component which allows a metronome to be seen instead of heard so the consistent beat will always be
perceived by the drummer. When a drum is struck, the skin on the surface of the drum will oscillate up
and down and the L.U.D.S. uses infrared sensors inside the drum to detect this oscillation, subsequently
lighting up an LED strip located inside the drum. The L.U.D.S. provides the infrared sensor framework for
future engineers to track when, where, and how hard the drum is hit. In metronome mode, the L.U.D.S.’
user interface requires the user to input the BPM and time signature of the desired rhythm and will then
light up the LED strip in a pattern consistent with the chosen parameters thus creating a visual
metronome. The sensor array is the array of infrared sensors for detecting drum beats which is located
within the drum head. The user interface is a collection of switches, rotary encoders, and a liquid-crystal
display for the user to input their desired parameters. The power supply is made up of both a
rechargeable battery and wall outlet power supply which both lead to a power regulator and can be
seamlessly switched between via a rotary switch. The LED array is an LED strip which is placed inside the
drum and acts as the output of the system. Each of these peripheral components are connected to the
MCU which is located on the device’s PCB. The L.U.D.S. meets certain engineering specifications relating
to durability, battery life, LED luminosity, and metronome accuracy.
