22 Transistor flasher in three colors
We will install an additional 10 kΩ resistor (brown, black,
orange) in series with the capacitor into the flashing circuit of
our last experiment. This will make the on-off ratio more bal-
anced. Another change involves the LEDs. The right transistor
can control more than just one LED. Here we have three of
them flashing in sync.
The oscillator
A circuit that automatically generates vibrations is called an
oscillator. Oscillators are important circuits in electronics and
computer technology. Many components used in a computer
work in unison. This clock cycle is preset by an oscillator, but
of course is working much faster than the flasher introduced
here.
