SecureLED: Better Access Control Using ATMega32

Introduction Overview SecureLED is an optical access control device which replaces current RFID or Magnetic Strip technologies with a cryptographically secure, contact-less device which communicates over commodity Light Emitting Diodes (LEDs). Project Summary This project started with one central premise: current physical access control systems are insecure in fundamental ways. We sought a way to …

How to drive a lot of LEDs from a few microcontroller pins. using atmega

Using the fact that many microcontroller pins have three states (+V, GND, or “high impedence”, you can drive N*(N-1) LEDs from N pins. So the little 8 pin microcontroller like a PIC12Fxxx or an ATtiny11 can drive 20 LEDs on its five available output pins, and still have one pin left for some kind of input. The current …
