Overview (resum en anglès):
One area of innovation in percussion groups is lighting. It is now fairly common to see drums with LEDs attached. Getting them to respond and light up according to the musician's interpretation is more complicated. The aim of this work is to produce a device that capable of lighting LED strips in response to drum strokes, proportional to its vibration.
An embedded system has been developed using a MSP430 microcontroller, powered by a battery and designed with low power consumption in mind. The goal was to end up with a working system, not just a prototype. It was first designed and tested on a protoboard and then on a printed circuit board with SMD components and its own housing and cables.
The main challenges were making the battery last for hours, finding a power supply that could handle all the LEDs, designing a circuit small enough to fit into a small case, creating an attractive lighting, detecting only the player's drum and making it all affordable.
The resulting device meets initial expectations. When LEDs are on, MCU uses PWM to control them, and when they are off it goes to sleep, drawing only 10 uA.
