The Breathing Light PCB board

The biggest PCB I’ve ever designed has arrived. And all RGB LEDs work as planned. Manufactured by JLCPCB. The diameter is about 260mm. It is still necessary to make the body and finish the firmware.

Biovälja spektrograaf

Andur mõõdab kehalt tagasi peegelduvat infrapuna (IR) kiirgust ja arvutab selle järgi pulsi sageduse. Samuti amplituudi, kuna on rõhk kõige kõrgem ja madalam, mida kajastab vastavalt põlevate LEDide hulk. IR väärtustest arvutatakse ka LEDide värv.
