Project 28 Triple Strobe Light
Build this circuit and turn on the slide
switch (S1). Adjust the blink rate
using the lever on the adjustable
resistor (RV), and by pushing the
press switch (S2).
Note: In rare cases the circuit may
not work at all settings on RV. If this
happens, move the RV lever to the
side near the strobe IC, turn the slide
switch off and on to reset the circuit,
and only move the RV lever over a
small range.
Project 30 Noisy Triple Strober
Build this circuit and turn on
the slide switch (S1). Adjust
the blink rate and sound using
the lever on the adjustable
resistor (RV), and by pushing
the press switch (S2).
Note: In rare cases the circuit
may not work at all settings on
RV. If this happens, move the
RV lever to the side near the
strobe IC, turn the slide switch
off and on to reset the circuit,
and only move the RV lever
over a small range.

Use the preceding circuit but replace one
of the LEDs (D1, D6, or D8) with the
speaker (SP).
!
WARNING: Moving parts. Do not
touch the fan or motor during operation.
Use the preceding circuit but replace the
speaker (SP) with the motor (M1, “+” toward
white LED), then place the speaker across
the points marked A & B in the drawing. Do
not place any fan on the motor.
The LEDs (D1, D6, & D8) flash, the speaker
makes noise, and the motor shaft spins or
wiggles. Adjust the blink rate, sound, and
motor spin using the lever on the adjustable
resistor (RV), and by pushing the press
switch (S2).
