Glen Akins build a USB Stack Light Controller based on PIC16F1459 and documents the process on this personal blog. He writes: After using the PIC16F1459 to build numerous USB HID input devices including a giant keyboard, a tiny keyboard, and a big red button, it was time to see if the PIC16F1459 could be used […]
OpticSpy – A Tool For Decoding Optical Data Transmission
https://www.electronics-lab.com/opticspy-tool-decoding-optical-data-transmission/
Optical data transmission offers a different way of sending data between objects without the drawbacks associated with radio-frequency and wired-communications methods. Visual data communication uses light beam as the medium of data exchange. Optical data communication has applications everywhere, to the fiber-optics that pushes your connectivity to the world and even that old-school TV remote […]
