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
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
