You’ll find many resistors in almost any electronic product and schematic. Since the most common resistor only has 2 legs, they are usually pretty simple to desolder. It’s good to have a bunch of resistors in various values at hand. In my experience, their values on schematics are usually an indicator, and you can divert slightly without too much impact on your project.

Variable resistors such as *photo resistors* and *potentiometers* are fantastic. Always salvage them, and their knobs. They allow for interaction with your circuit.
