Color & Brightness Testing Multiple SMD LEDs

Loving this simple but effective setup for testing SMD/SMT LEDs by Lucky Resistor. Also shown or discussed over at the original blog are tips like using different color headers to distinguish the anode from cathode ends of the LEDs, and also a sticker on the underside of the PCB denoting the LED used – smart! And yeah the light coming off that green Sloan LED is fantastic!

Today I tested a number of SMD LEDs for the plant watering sensor project. I soldered all 13 LEDs I shortlisted onto a small board and connected it to an Arduino Zero Pro. So I could try the different flashing styles I planed to use more or less automatically. That way I could focus on the LED flashing itself, without being distracted by switching cables.

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.
