Led anode et cathode

NettetFor an LED to work it needs to be connected to a voltage source with the correct side. The voltage supply side of the diode is the positive (+) side, this is called the anode. The negative side is called the cathode. Because diodes are made of semiconductor material, they have a very specific voltage where they will turn on. NettetWhen you connect a lot together (for example, an LED or LED strip and a micro controller) they will likely have a common ground, but different supply voltage. Most voltage regulators will have a common ground, a high voltage input and a low voltage output. To switch the cathode (or ground or 0 V side) you can use a logic level, n-channel MOSFET.
