IMXRT Drum Pad

Hi All,

This is Mini Drum Pad build in with IMXRT1015. Also it has AFE shield board which is used for capsense buttons.

IMX RT is, using SAI to play the audio file at 16KHZ. I have created 12 samples (.wav file) and the raw data is stored in the music file. Based on the capsense button press triggering the sound effect.

Speaker I used is from Boat, it has internal battery so only thing required is to feed the Aux input from IMXRT EVK.

I felt that, button sense over I2C bit slow due to that having the limitation of playing the music as faster. Anyway its just demonstration of my concept.


This drum has 3 modes of music set. The mode can be changed with the help of mechanical switch (push button). Also the volume can be controlled via Potentiometer.
