LED Interfacing with 8051
Light Emitting Diodes as we know are PN Junction diodes which emit light when forward biased. Well, lets say they simply emit light! They come in various packages through hole as well as SMD. They are basically used to:
- Indicate System status, ON/OFF etc.
- LED lighting: Well, recent technology trends show a increasing usage of LEDs in domestic and industrial lighting. And there are cool projects in DIY community too. Check the Lumapad for instance.
- Also you could build some display projects like the persistence of vision[POV].
Well, lets just start interfacing a simple LED with the micrcontroller.
