From the incoming data encoded in Port0 integrated 7-segment display with 7447 microcontroller integrated ulaşır.7447 binary code from the 7-segment display is used to show.

So when it comes to 0000 a, b, c, d, e, f, g edu yanmaz.7 segment display LED lights bağlanmıştır.paralel parallel to each other using the same bus to the 7-segment display 7 segment display by selecting different at different times that instant If you have selected to display the data which goes to him.

In practice, common anode 7-segment display is used. Port 2 is connected to the terminals of transistors oval. Transistors display the benefits of riding. that is used to select one of a display. With the help of a single button port3 hour, minute, alarm settings are made.

Port1.0 a alarm fitted. One end of the button being available to the microcontroller used in the other end of the earthing. If the button is not pressed resistance feature is to send a signal to the microcontroller 1. So the trigger button enabled microcontrollers with 0.

To Prepare The Visual Graphic LCD Pixelformer
As the program does not dial the code worked for me pretty pictures of Pixelformer but edit pictures or to create a handy program very practical on a pixel-by-pixel, you can have a lot of property is the closest way to edit, I used the zoom ratio to edit logos ready and very good great bitmap editor program to open the image files “file” menu in the normal “import” in the same way again after you are enough to eject the “export”. Pixelformer-free and 800 KB in size

12V to 230V DC AC Inverter Circuit
DC 12V to 230V AC CMOS inverter circuit cd4047 monostable / astable multivibrator based on an integrated battery voltage 12v-230v AC 50hz or 60hz as increasing the output frequency can be adjusted.
This simple drive can serve as a source of voltage 230V/50Hz for appliances to power by the transformer used, which can be compact fluorescent lamps with ballast tlumivlou DZ series and classic, small motors, shavers, power televisions and other consumer electronics, backup gas boilers during a power failure. and current clip. Are used both in the home and at the cottage, ala especially of car, boat and everywhere where there is no grid 230. The connection is very simple

Magnetic Levitation Circuit
These coilguns with levitation control circuits are great! Now… How can you use them for magnetic levitation? This is slightly off-topic from coilguns, but magnetic levitation has many common design principles and is a little easier to build!
If you hold two permanent magnets close together, you see that one of them will jump strongly toward (or away) from the other. In 1842, Samuel Earnshaw expressed the perversity of inanimate magnetic objects in his theorem. It explains this frustrating behavior will always prevent you from suspending one permanent magnet above or below another, no matter how one arranges the two magnets. However, an active control circuit can get around this problem by rapidly adjusting the magnet’s strength.
