SMD LEDs Tests

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.

This is the board I made. Very simple but functional. I used red and blue male header to mark the anode and cathode of the LEDs. There is a sticker on the bottom with the LED numbers on it.

I mounted everything on a very small breadboard and did all connections to the Arduino.

SMD Components Under the Microscope

Today I took some photos from common SMD components using a microscope. From naked eye, this components look so tiny and fascinating perfect. Looking at them using a microscope, they do not look that perfect anymore.

I cropped the pictures to make the picture better visible at lower resolutions. I always put a scale, which measures 1mm, on each photo. See each picture caption for a description of the component and more details.
