Project 105 Funky Light & Sound
Build the circuit as shown
and turn on the switch
(S1). The color LED (D8)
is used to control the
strobe IC (U23), producing
unusual effects.
Use the preceding circuit, but replace the
color LED (D8) with the 100k
Ω
resistor (R5)
or the 5.1k Ω resistor (R3).
Project 107
Light & Motion
Project 106
Light & Sound
Adjustable Light & Sound
Modify the preceding circuit to match
the one shown here. Use the lever on
the adjustable resistor (RV) to control
the light & sound. At some settings the
white LED (D6) will not light, or will
appear to be on continuously.
Project 109
Adjustable
Light &
Motion
Use the preceding circuit, but
replace the speaker with the
motor (M1) and glow fan
(motor “+” toward S1).
Project 108
Repeat projects 105 & 106 but replace the
speaker with the motor (M1) and glow fan
(motor “+” toward S1).
