Introduction How many times you needed some remote control to handle some electric device ? Many times. There are lot of remote controls like infrared, RF, SMS (like my other circuit) and more. The basic small-range remote controls are 2, Infrared and RF (Radio Frequency). One of the weaks of Infrared is that the signal […]

Introduction: As you know the AT90S1200 microcontroller includes an internal RC oscillator that is disabled by default. If you want to change it (enable or disable) you must to program it with parallel mode. The most programmers work on serial mode that is not possible to program this fuse bit (RCEN). With this stand-alone programmer you can enable

The LEDMATRIX interface News: Now with lcd4linux driver I recently purchased 10 SLM1608 (SLM1606) LED matrix display units from Ebay (you might also contact the seller directly at [email protected]). These are 16×16 LED matrix units with a green and a red LED per pixel allowing each pixel to be switched to either green, red, amber

Timer are widely used in industrial and domestic application for automating tasks. Microcontrollers can be used to design versatile and accurate timers with ease. Here I present a simple timer that can be used to turn on/off a load after user specified time. The Timer uses a standard 16×2 lcd module for user interface (UI).
