Step 21If you have problems...
a) Turn the knob on the 5K Ohm variable resistor. That's the volume control. It could just be set low.
b) You've messed up somewhere. It happens. Go back through the directions and make sure everything is in the right hole. If you've got even one mistake the entire circuit could fail.
If this didn't work right the first time don't fret! Just double check every connection. Make sure all the jumpers are in. Make sure your 9V is charged (you could always lick it).
