LED Me Know: Get alerted when you’ve broken a test as you code #Arduino #LEDs

Neat project from Johnny Copperstone

LED Me Know is a little side project to enhance a front-ender’s development environment, but really, it’s just an excuse to play around with an arduino.

Wouldn’t it be cool to have some LEDs connected to an arduino, connected to your development tooling, letting you know when you’ve broken a test as you code?

Well, that’s the idea.

A group of LEDs accessible by gulp, in turn making the tooling workflow slightly more visual. If you’ve got gulp tasks to automate running your tests as you code, you could then hook into the reporting, and display whether the tests have passed or failed by flashing the LEDs with green or red respectively.

So yeah, it LEDs you know (pun obviously intended) when you’ve broken your code as you code.

NeoPixel Ring – 12 x 5050 RGB LED with Integrated Drivers: Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with 1.5″ (37mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. Read more.
