KIT 21. TWO STATION INTERCOM This Kit is a two station intercom. It uses two wires to run between each intercom unit. Each is self contained with its own battery, speaker, microphone and amplifier circuit based on the LM386. To use it you just push the switch and talk. Releasing the witch automatically turns thes
Intercom Circuit - ElectroSchematics
In this intercom schematic, the 8 ohm speakers is used as microphone and listening speaker. The 10K potentiometer controls volume and the total gain can be set with de 5k R. Use a double switch with 2 positions so when one is used to talk and the other one to listen. The switch will be in the house. Intercom circuit diagram
Simple Two Way Intercom Circuit Diagram
Jan 26, 2018The complete circuit diagram of this Intercom Project is given below. As you can see the circuit is very simple and can be easily built over a breadboard. The main concept behind the circuit is the use of LM386 audio amplifier which receives the audio signal from microphone, amplifies it and plays it on the speaker.
High Quality Intercom - circuit diagrams, schematics
A very high quality intercom, which may also be used for room monitoring. Circuit diagram. Notes: This circuit consists of two identical intercom units. Each unit contains a power supply, microphone preamplifier, audio amplifier and a Push To Talk (PTT) relay circuit. Only 2 wires are required to connect the units together.
Intercom Circuit - ElectroSchematics
The intercom schematic fulfills its tasks – to provide a reliable communication line and is very simple to construct. The circuit is made up of an amplifier, two switches and two loudspeakers. If additional stations (speakers) are wished, additional switches are just incorporated into the circuit. IC LM382 is used as the final amplifier.
