Involving some IR LEDs, perhaps a ... The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide.

Osram Opto Semiconductors was able to sink a surface-mountable infrared (IR ... SFH 4140 side-looking LED extends a mere 0.6 mm above and below a printed-circuit board (PCB).

There are a few options to do similar things with PCB layout, including tscircuit. There’s a walk-through for using it to create an LED matrix and you can even try it out online, if you like.

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR ... electronics design, and leading on PCB layout oriented to EMC. Jorge also has seven years ...
