In this article, double-melodic ring made with KS5814 integrated circuit will tell you. Integrated KS5814, in which two principal melody, produced by SAMSUNG company, is a 14-pin integrated. In that the logic operation of the circuit;
1 button is pressed out a melody similar to bird sounds from the speaker. 1 and 2 buttons simultaneously while pressing the home phone melody sounds similar to the sound.
Moreover, the circuit of resistors and capacitors tones can be adjusted by changing the values. Circuit used a variety of purposes.

PIC16F84A 24 LED 12 programs light show
PIC16F84A LED light show with 24 applications were submitted by Project Articles Sharing section I thank him. Pic 16f84 circuit assembly prepared with software installed on the pic microcontroller output used to replicate the integrated 8255
Hello friends with you “advanced PIC applications from the book” I wrote 24 led light show I wanted to share my time took menial job, but if it works, I’m happy for you
Circuit pressing the start button begins to work 12 LEDs are illuminated each program separately Can be repeated until the desired it enough to make any changes to asm file
