Trimpots for Prototyping and Breadboards

Trimpots for Prototyping and Breadboards via Dangerous Prototypes

Trimpots (also called trimming potentiometers) are small variable resistors installed on printed circuit boards for fine-tuning and other adjustments. The next page shows the inner workings of trimpots, but we’ll begin by taking a look at trimpots that you can buy for your projects. There is a huge variety of trimpots available. We’ll focus on those that have one-tenth inch (2.54 mm) spaced, PC solder pin, through-hole leads. These trimmers are compatible with solderless breadboards and perfboards favored by hobbyists.

These are our favorite trimpots, perfect for breadboarding and prototyping. They have a long grippy adjustment knob and with 0.1″ spacing they plug into breadboards of perfboards with ease. This is the same pot that comes with our character LCDs and tutorial packs
