Lab: Tone Output

Time for the tone lab.

5. The photoresistors gave me an input range from 33 to 668.

I could only scrounge up a 16 ohm speaker. It was really quiet, so I substituted a 220ohm resistor in place of the 1Kohm resistor specified in the schematic. This gave the volume a bump.

7. Basic tone production using a photocell-based voltage divider

8. Playing series of tones
