Hi- have we had any issues where the IOT Relay you sell (https://www.sparkfun.com/products/14236) conflicts with the MP3 Player Shield? (https://www.sparkfun.com/products/12660) My Sparkfun MP3 shield is the older VS1053 MP3 shield, but it works fine on its own. Also a simple program with the IOT relay works fine on its own- but when I combine the two I cannot make them work. Here is the project I am attempting to duplicate: https://create.arduino.cc/projecthub/cr … box-41cc38 Here is the simple code I use for the IOT relay:
#include <SPI.h>
//Add the SdFat Libraries
#include <SdFat.h>
#include <SdFatUtil.h>
//and the MP3 Shield Library
#include <SFEMP3Shield.h>
SdFat sd;
SFEMP3Shield MP3player;
void setup() {
//start serial connection
Serial.begin(9600);
//configure pin 2 as an input and enable the internal pull-up resistor
pinMode(4, INPUT_PULLUP);
pinMode(12, OUTPUT);
}
void loop() {
//read the pushbutton value into a variable
int sensorVal = digitalRead(4);
//print out the value of the pushbutton
Serial.println(sensorVal);
// Keep in mind the pull-up means the pushbutton's logic is inverted. It goes
// HIGH when it's open, and LOW when it's pressed. Turn on pin 13 when the
// button's pressed, and off when it's not:
if (sensorVal == HIGH) {
digitalWrite(12, LOW);
} else {
digitalWrite(12, HIGH);
}
}]
IOT relay works as intended with this code. But when I add this line, or any other line referring to the MP3 Shield: nothing occurs. It verifies fine, and complies and uploads fine, but the line or any line referencing the MP3 shield causes the IOT relay to not work. I know that I need to add this line that slows down the MP3 Shield speed, but it will not allow anything further to occur:
//Initialize the MP3 Player Shield and SD card
sd.begin(SD_SEL, SPI_FULL_SPEED);
I can make the Halloween project work without sound, but I’d love to get this prorgam working to include the MP3 shield. Thanks for whatever help you can provide.
