LC Meter: Â Schematic Source code This is the project I am currently working on (2010-01-23). The LC meter is based on Elmcie or Elsie and other similar LC meters. This project is in a very early prototype stage and is at the moment only capable of measuring inductors. Even though I have build the first […]

An Atmega128 microcontroller has got 4K of built in static RAM, which is pretty enough for small and medium range projects that do not involve huge amount of data processing. But if you think you need more than that for your application, you can expand it by adding an external RAM chip. This article shows

This is a digital clock project based on an ATtiny26 microcontroller, displaying time on four seven segment LEDs. The seven segment LEDs glow bright white and are multiplexed through PORTB pins, whereas the segments are driven by PORTA pins. The time is normally shown in hh.mm format but it can be switched to display mm.ss
