In this GreatScott! video, Scott decides to compare the wire nut connectors, common in the US against Wago connectors, more common in Europe. Scott tests for ease of use, problems, speed of application, reusability, size, price, pull test, resistance, and flammability.
In the end, both connectors work great, with Wagos being more expensive. But if you don’t mind spending the money, Wagos seem to have some real advantage over nuts for ease of use, speed of application, and reusability.
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.
