First, my apologies for seeming a bit rude in earlier posts. This has been turning out to be a frustrating project.
Second, I am posting some updated code below.
I am using five sensors that consist of a voltage divider with a photo resistor feeding a BJT and a red laser pointing on the photo resistor so that when someone walks through the beam the BJT turns on and sends 5VDC to the Arduino Uno digital input pin. I have the Wave Shield attached to the Arduino Uno and have various short wave files on the SD card. I also have various arrays of LED's on two output pins and a small DC motor attached to another output pin. I am using IF and ELSE IF statements now to read the input pins searching for one to go high from the 5VDC from the sensor. Each IF/ELSE IF statement has a different LED blink and a different audio file. When commenting out sensor 2-5, sensors 1 and 2 trigger outputs as they should but when I include all the sensors in the LOOP(), none of the sensors will trigger an output.
I have now discovered that if I only use three different audio files between the 5 conditional statements all 5 sensors trigger outputs. If I try only 4 audio files, none of the sensors trigger outputs.
I have tried inserting PRINT statements to print to the serial monitor for some debugging to see where it is getting stuck but I can't get that to work.
I haven't seen anything that limits the amount of audio files to be used. Even the WAVEHC example code for the six buttons there are six different audio files to be played.
Any input will be greatly appreciated.
In the mean time I will rewrite it to only use three audio files as this is my final project to graduate and is due this friday.
