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 …
AVR Microcontroller based Temperature Controller, it uses LM35 Temperature Sensor for measurement of temperature and 16×2 LCD is used to display temperature set point, Heater Status and current temperature, It controls temperature by turning on and off of the heater using relay. This project is very useful for controlling of temperature, It can be used …

For a long time I had a layout for this circuit, but could never build it, because the layout was to small to be made by tonertransfer. So it was the first layout I made with my new exposure unit. It’s quite small, so it fits under the LEDMatrix itself. Therefore only SMD parts are used. It took three trys …

This tutorial shows how to implement the Analogue to Digital Converter (ADC) function on ATMega32 using C code. It consists of code examples, and the meaning of some nomenclature such as sampling rate, and resolution. However before we get to the code, let us start from the beginning. The ATMega32 has a built-in 10-bit ADC. The input …
The 4×4 LED Display was my first project with a two-layer circuitboard layout. The alignment was not 100% optimal, but sufficent. I wanted to make the board as small as possible, so the parts had to be stacked at some places. The square LED’s were painted black on the sides to keep the pixels sharp. The rows and columns …

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 …
