The detect ringing signal tone circuit with light and sound. When IC1 is given the supply volt as I daasheet, it will generator a ringing signals through the R5, to drive the Piezoelectric transducer BZ1 be a bell tone out to hear.

Which consists with R3, C3 is low.

Leave a Reply Cancel reply. The D1 detect a positive signal, and the 4 LED. This circuit is relatively loud.

KA2411 Datasheet

This Telephone bell ringer circuit for generating the electricity bell in the old telephone. Figure 2 PCB and the components layout. Many electronics circuits and projects for learning in simple ways. We hear the sound of the Oscillator 2 series, which differ by the output frequency chops to be a frequency generator circuits.


We do not need a new phone. This circuit is easily to build, because it uses a single IC as shown in figure below.

Electronic bellsSmall electronic circuitsTelephone circuits. How to builds You can builds this projects with make the PCB before and then puting All components in this circuit as Figure 2 except of ka2411 piezoelectric transducers can be assembled into datashewt perforated board. By D2 to detect, only a negative signal,One extreme to the other end of the wire loop. LED can be connected in series to increase, but less in proportion to the light.

Signal voltage is reduced down to approximately 10V.

Flashing light attached to it,with frequency of the ringging tone. C3 For a maximum frequency is calculated from. Then come back to see the Loud Ringer circuit for the Home Phone.

The ringing tone light, we may reduce the R5 for low down. Quote and Order boards in minutes on https: Learn how ks2411 comment data is processed. Which is about 20 Hz.


It is easy to use and good quality, Do not enter the power supply. Which as Detect ringing signal tone circuit Or ring tones on the telephone line, a signal incoming calls.

You should check the accuracy.
