#include <SoftwareSerial.h> #include <DFPlayer_Mini_Mp3.h> #include <Wire.h> #include "Adafruit_MPR121.h" // You can have up to 4 on one i2c bus but one is enough for testing!

Serial.begin(9600); Serial.println("Adafruit MPR121 Capacitive Touch sensor test"); // Default address is 0x5A, if tied to 3.3V its 0x5B // If tied to SDA its 0x5C and if SCL then 0x5D if (!cap.begin(0x5A)) { Serial.println("MPR121 not found, check wiring?"); while (1); } Serial.println("MPR121 found!"); mp3_set_serial (Serial); //set Serial for DFPlayer-mini mp3 module delay(1); //wait 1ms for mp3 module to set volume mp3_set_volume (15); } void loop() { // Get the currently touched pads currtouched = cap.touched(); for (uint8_t i=0; i<12; i++) { // it if *is* touched and *wasnt* touched before, alert! if ((currtouched & _BV(i)) && !(lasttouched & _BV(i)) ) { mp3_play (i); delay (100); } } // reset our state lasttouched = currtouched; // put a delay so it isn't overwhelming delay(100); }
