Project 285
Clicker
The color LED turns off briefly when
it changes colors. What you hear in
the speaker is the change in current
as the LED turns on or off.
Build the circuit, and turn the slide switch (S1). The color LED (D8) is
flashing, and you hear a clicking sound.
Modify the preceding circuit to be this one, which adds echo effects.
Turn on the slide switch (S1) and push the press switch (S2) to see the
color LED (D8) flashing and hear a clicking sound. When you release
the press switch, the color LED shuts off but you hear echo effects. Use
the lever on the adjustable resistor (RV) to set the echo level.
