Two Way Intercom engineersgarage Fig. 1: Prototype of Two Way Intercom Circuit on Breadboard LM386 is a very popular and widely use 8 pin audio amplifier used to amplify sound signals. The circuit describe below can also be used to amplify the sound signals from mobile output, CD player or it can be used in cars to amplify sound signal. Top 10 Fundamental Op Amp Circuits | Arrow The most basic circuit is the voltage buffer, as it does not require any external components. As the voltage output is equal to the voltage input, students might become puzzled and wonder whether this kind of circuit has any practical application. This circuit allows for the creation of a very high impedance input and low impedance output. 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 Intercom Using LM386 | Electronics For You Keep in touch with your family members from one room to another and also from outside areas such as the garage, using this intercom circuit for bidirectional communication. The advantage of this circuit is that there is no talk listen switch as many intercoms have. The circuit is built around two low power LM386 audio amplifiers. Fig.
