Knight Rider Lights Project

  This is a simple knight Rider light system that can be built using well known  popular integrated circuits.
 




                                              Circuit diagram for standard LED output.

                                              This set up is ideal for running off a car battery.             

You can use 12V bulbs for the output, simply substitute the IC for the LEDs, the bulbs are then connected to  the IC's outputs.

Led Clock

12Hr Led clock using  16F628.

Using only 2 capacitors, 3 resistors, 4 seven-segment Display, 1 xtal, 2 switches n.o. and 1 Microcontroller PIC, you can build this Digital Led Clock. you can use common anode or common cathode display, just select the display type. Here is the pinout information:

Bar Graph LED Project

  
This bar graph LED battery level indicator project is based on LM3914 monolithic ic from National Semiconductor that senses the voltage levels of the battary and drives the 10 light emitting diodes based on the voltage level that is detected.
