Comments: How to Read a Schematic

Good beginner's reference.

You have the opportunity to explain IC gates but don't for some reason. The picture of opamps shows U4 and U5, but given the mention of more than one opamp in a package you should have probably labeled them as U4A and U4B. Then later in the name designator (really? I thought the more common term was "reference designator"?) section refer back to what the "A" and "B" mean at the end of the ref'ds in the opamp example.

I also hope that the example schematic in the "Recognize Voltage Nodes" section isn't someones idea of a good schematic. Mixing and matching of IC and U ref'ds... Ugly. (But this image is another example where the A/B notation of gates could be referenced.)

this is really good for the beginners and following this simple tutorial they could master the art of reading schematics. thanks a ton.

Good Start up tutorials for beginner. Thanks a lot
