Adjustable color burst generator
The generator, drawing, generates alternating in time multi-colored flashes of light with a smooth change in their brightness.
The device consists of a master sawtooth pulses generator and a two-stage amplifier loaded with light-emitting diodes, for example, red and green.
Low-frequency master sawtooth pulses generator is based on the Schmitt trigger. The rise and fall time of the pulse and its frequency are smoothly controlled by the potentiometer R5. The pulse repetition frequency can also be switched stepwise by the switch SA1, the frequency ranges, respectively, are 0.5-2 Hz; 2-10 Hz and 10-50 Hz.
