Final working version of code: #include <Audio.h> //#include <Wire.h> //#include <SPI.h> #include <SerialFlash.h> // GUItool: begin automatically generated code AudioPlaySdWav playSdWav1; AudioMixer4 mixer1; AudioOutputMQS MQS1...

Thank you so much @h4yn0nnym0u5e I tried the suggestions described above, except for the "while" statement (because I wasn't sure what it was doing and wanted to make incremental changes). These changes fixed the LED so that it would light up at the appropriate time. But still no sound...

Everything is soldered, except for the LED that is not shown in this picture.

Same result - the LED does light up when the ground is connected to the pin 13 and the + lead of the LED is connected to power - this also causes an orange light to illuminate on the teensy. The status of the IR sensor does not effect the LED in this condition.

I also tried to connect the LED to pin 29 (input from IR sensor). The LED is on and then turns off when the sensor is activated.

I think my audio file is sorted. I also reformatted the sd card and made sure it was formatted in the correct way. Still not working. Next, I downloaded a sample audio wav file from PJRC here. Still not working.

It probably wasn't before. I just spent some time working in VLC media player and I think these parameters are set now.

Thanks so much for responding. I started here and I ran the code in that thread and had a good [loud] tone on the speaker. So it seems that I have eliminated the MQS output and speaker as potential problems. So, I think my problem is either the code or the ability to access the SD card...

deadline is here... anyone know what is wrong and/or why this isn't working?

Thanks very much for the response. 1. I edited the original post for the code. 2. Yes, I am using pin 12 for audio output (green wire) 3. I have tried commenting out these commands (see below) 4. I tried commenting out these also 5. I also commented out the volume control command...

Although still not working, it is doing something different now. When I connect power, I'm not hearing as much static through the speaker and the Teensy red light blinks about 8 times. Sensor is still lit up and reacts to motion as before. Also, when I plug the usb into my laptop the Arduino...

Hi, I'm trying to figure out why my project for my daughter's Valentine's day box isn't working. We used this project on YouTube. I *think* I wired/soldered everything correctly. The idea is a Valentine's box that looks like a dog house. When the IR sensor is tripped, the speaker is supposed...
