When was the last time you went to the local church? Did you ever have a closer look on the church’s environment? If you want to do something and contribute to the local community, especially the local church, then you’ll find this church bell controller is what you’ve looking for…

As you can see on the above figure, this is the main circuit for the church bell controller. The whole system is based on an ATmega32 microcontroller and a 24LC32 EEPROM memory is being included into the circuit board too!

Although it looks quite simple, but this church bell controller has many useful features, such as:

• Over 75 types of melodies (You can download and reset the melodies whenever you want),
• The automatic correction in case of power loss,
• The manual correction of electromechanical clock,
• The display time is included with backup battery,
• All the formations are displayed on 4×20 LCD.

Beside that, the menu browsing can be done by six buttons at the face of the circuit’s box (Menu, Up, Down, Enter, Start, Stop) and it can control up to 5 church bells and 1 clock in the same time!

Go and build the church bell controller and give it to the local church. As a return, God will bless you here…
