Electronic Church Bell Controller based on Microcontroller AVR

Electronic Church Bell Controller based on Microcontroller AVR
This circuit designed<> by Antonis Pontikakis. It's used ATmega32 microcontroller as the main part. At the circuit, there are 2 24LC32 eeprom memories, the 1st for internal standard melodies and the 2nd one is for user's compositions.
As control, he created a menu that will be appeared on 4x20 LCD (Liquid Crystal Display). For browsing the menu there are 6 buttons in front of circuit's box (Menu, Up, Down, Enter, Start, Stop). All firmware only use 19 Kbytes flash memory of ATmega32 microcontroller writen in C compiled used Code Vision AVR compiler. If you need for more information don't be hesitate to send him an email.

Features

  1. More 32 different melodies ( ADAM, PANYGJRJKO, AGJORJKO, etc)
  2. Control of electrometrical clock of church with the production of pulse of duration 1Sec each one minute.
  3. Automatic correction in case of power loss.
  4. Percussion of clock each half but also entire hours, with possibility of choice of hours of silence (for tourist regions and hours of common quietness).
  5. Manual correction of electromechanical clock.
  6. All regulations become with the help of guidance (menu, up, down, enter, start, stop)
  7. When it runs a rhythm we have the possibility of increase or decrease her speed,the information will stored in memory 24LC32.
  8. Display of temperature (DS1621).
  9. Display time DS1307, with backup battery.
  10. All the in formations are displayed on 4X20 LCD.
