We dig the lil’ rubber nubbin on the popular 75mm long 10KΩ slide potentiometer so much, we thought folks might like a pack of three for their own DIY slide pot project. They have a grippy plastic knob with a white stripe marking and are very satisfying to slide back and forth.
Add some jazz & pizazz to your project with a color capactive touchscreen LCD. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlight) and colorful! 240×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display. As a bonus, this display has a capacitive single-touch touchscreen attached to it already, so you can detect finger presses anywhere on the screen. (We also have a resistive touchscreen version of this display breakout)
Nikola Tesla famously said, “If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration.” Kelly Heaton followed Tesla’s advice to invent a practice that she calls Electronic Naturalism: the study of electrical patterns in living and life-like entities.
Snap action blocks are perfect when you have to quickly wire up a bunch of free-hanging components, and you don’t want to solder. They’re much easier to use than wire nuts, and of course, they are reuseable and do not require any crimping!
This is a 2 to 6 wire block: there are two separate inputs and two sets of three outputs. They’re color-coded so easy to follow; the blue and red inputs match the colored outputs. Great for basic power or signal fan-outs.
This is a 3 to 9 wire block: there are three separate inputs, and three sets of three outputs. They’re color coded so easy to follow, the green yellow and red inputs match the colored outputs. Great for basic power or data fan-outs.
Sparky the Blue Smoke Monster shows up whenever the magic smoke is let of of an electronic component. And his very favorite is whenever folks first start with electronics and robotics: wiring up a motor or solenoid or high power LED is a perfect recipe for getting that blue smoke out of an Arduino or Raspberry Pi. Why? Because these high-current devices can’t be connected directly to a GPIO pin on a microcontroller! They need to have a transistor / MOSFET driver, plus a kickback-protection diode that will absorb the inductive ‘kick’ caused by turning on-and-off motors and solenoids. Without that driver and diode – your tronix will go poof!
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.

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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
