A resistor limits the current going through. This amount of *resistance* is expressed in Ohm (Ω) | Everywhere! | https://upload.wikimedia.org/wikipedia/commons/thumb/4/44/IEEE_315-1975_%281993%29_2.1.1.a.svg/200px-IEEE_315-1975_%281993%29_2.1.1.a.svg.png | knob, pot, potentiometer, variable resistor, dial |
You’ll find resistors in nearly every electronic device and schematic. It’s useful to keep a wide range of values around, from 1Ω up to 10 million Ω. Their colored bands indicate their valuewaar kun je dat vinden. 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—like photoresistors and potentiometers—are especially worth salvaging, along with their knobs1. They make your circuit interactive with your circuit.yes, niets meer aan doen
Types of resistors
- Carbon or metal film resistor Comes in different values, marked with color bands
- Photoresistor Changes resistance based on amient light levels.
- Potentiometer A knob-controlled resistor.
- Stereo potentiometer Controls two channels at once, often used for stereo audio.
- Slide potentiometer A slider-controlled resistor.
- Trimpot A small, precise variable resistor you adjust with a screwdriver, used for circuit calibration.
- Thermistor Changes resistance based on temperature. ff alle lijsten checken met wanneer ze wel niet met een punt moeten eindigen - ook footnotes

I've found a lot of old gas stoves left out for trash collection. They often have nice knobs, that can be pulled off without need for tools. ↩︎
