Video from Arrow Electronics: ‘LED Colors by Wavelength’ | @Arrow_Dot_com
Like testing pens at a stationary store it’s always nice to actually *see* the LED you’re considering purchasing – even if it does have a datasheet. So this quick video from Arrow Electronics is fun because they quickly scroll through ~30 of their through-hole LED offerings, from one end of the spectrum to the other. Because the difference for example between 565nm, 571nm, and 575nm can read on paper like too little to make a difference but in reality it could make or break your project’s look and feel (or even your contract with a client!).
Laura wanted to show people what wavelengths correspond to which color variations to help when ordering LEDs.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
