Anode & Cathode: LED diode scheme

soldering led diode

Sometimes some people don’t like led diode colour on their computers and some people would like to replace the red diode for a blue one. So here is a LED diode polarity scheme when you will do soldering on PCB. This article is mainly for me – I am always forgetting which connection is anode + and cathode as I am not soldering diodes every day.
