555 Timer IC as an astable multivibrator Circuit diagram and working are explained very clearly in this post. 555 Timer IC as an astable multivibrator Circuit diagram and working are explained very ...

Adding the long-first-pulse malady in less traditional 555 astable topologies including CMOS- and bipolar-based oscillators that generate 50:50 symmetrical square waves. Figure 1 The problem—the first ...

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2, and ...

Here’s an interesting implementation of a classic: the 555 timer as astable multivibrator for the noble purpose of making weird music. [pratchel] calls this a Morgenflöte or morning flute, indicating ...
