EFA:002 – Schematics & 555 Timer


I have been using Fritzing to draw most of our circuits in a breaboard view. It is great for simple things, but anything more complicated gets a little bit difficult to illustrate. Therefore, we should learn how to read schematics.


See the components page for description about capacitors.

555 Timer

The 555 timer is a very commonly used IC for all kinds of projects requiring either a pulse or a clock signal.

I have compiled a page for different 555 circuits.
