You Can Measure This Fundamental Quantum Constant Using LEDs WIRED

Wired shares this pretty in depth look at Planck’s constant. Plank’s constant is a fundamental constant like the speed of light or an electric charge. Learn more how it funtions and how you can measure it with some basic LEDs. From Wired:

The Planck constant has a value of 6.626 x 10-34 joule-seconds, and it mostly appears in calculations dealing with quantum mechanics. It turns out that really tiny things (like atoms) don’t actually behave like big things (like baseballs). At this super-small scale, our classical view of physics doesn’t work.

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.
