Project #57 Laser Flasher
Project #58 Flash & Flicker
This circuit demonstrates how
toy laser guns can be
designed.
This circuit demonstrates how
continuous laser gun sounds
can be generated.
When you press the press switch (S2), the integrated circuit should
start sounding a very loud laser gun sound. The red LED will flash
simulating a burst of laser light. You can shoot long repeating laser
burst, or short zaps by tapping the press switch.
Build the circuit shown on the left, which uses the Space War
integrated circuit.
Set the switch on and the speaker makes exciting sounds. The output
of the IC can control lights, speakers, and other low power devices.
You may replace the speaker (SP) with the 2.5V lamp (L1), and the
bulb will flicker. You can also use the LED (D1) in place of the lamp
(position it with the “+” side towards the 6-snap).
