Build the circuit as shown. For best effects, place one of the LED
attachments over the light on the color organ. Turn on the switch (S1)
and move the lever on the adjustable resistor (RV) to change the tone
of the sound and “speed” of the light.
Build the circuit as shown. Connect the white LED (D6) to the red &
black jumper wires. Turn on the slide switch (S1). Go to a water faucet
and adjust the faucet so water is dripping at a steady rate. Dim the room
lights and hold the white LED so it shines on the dripping water. Try to
set the lever on the adjustable resistor (RV) so that the dipping water
drops appear suspended in mid-air. You may need to adjust the drip
rate on the faucet to make this work. You may get better results if you
replace the 100kW resistor (R5) with the 5.1kW resistor (R3). Also, try
setting the strobe rate to minimum and adjusting the drip rate.
