Crimping cables kind of sucks, but it sucks even more when your cables are poorly crimped and fail in subtle (or not so subtle) ways as soon as you finish screwing everything together. Did you just order a couple thousand crimped cables from China and want to know if they’re well made? Are you trying to make sure your own crimped cables are OK? Molex has a great guide called the QUALITY CRIMPING HANDBOOK that sheds some light on what makes a good crimp.7
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.
