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.
- There will be schematic symbols for all the components in the component page.
- A tutorial about schematics
- More schematic symbols
The 555 timer is a very commonly used IC for all kinds of projects requiring either a pulse or a clock signal.
