Two 555 Timers Bell Circuit Diagram

This is a simple IC based Two 555 Timers Bell Circuit Diagram. This simple Bell circuit uses two 555 timers. The frequency is controlled by the capacitors that must be preserved almost identical in value to each other for best results. Fine tuning is done with R1 and R2. The decay time is controlled by R3.
