We’ve got battery holders for all sorts of needs and projects! Waterproof? Here ya go. With an on/off switch? Easy peasy. Here’s our latest addition in classy Adafruit black: 2 x AA Battery Holder with Premium Header Wires. What’s so special about ’em? Well you can plug them right into a breadboard! No need to fight with those skinny stripped wires you normally get. Of course, you can always still solder them into a PCB.
Use with any alkaline or rechargeable batteries for about 2.5V to 3V output.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
