How to use the DIY clap switch September 16, The wave is like something else.

Intercom Using LM386

For power supply, you can use an AC-DC wall adaptor, dry batteries or rechargeable batteries. The complete working of the project is shown in the video below; you can also go through it if you are confused on how to use it. Please enter your name here.

You can use the amplifier module for your project. These are just like landline phones but, you do not need an operator, the voice received from one end will be directly transferred to the receiver on the other end. Apr 26, 6. The preamplifier usng exhibit instability at very high frequencies. The lj386 can also run on voltage between 5V to 12V so choose a power supply which you are comfortable with. Tuesday, January 1, Clap switch December 18, Or can i have your contacts?


Is the 5 meters distance, line-of sight? HelloI’ve made this intercom circuit and it works just fine, however, i want to make it wireless but i don’t know howany ideas? This project brings in the childhood memory of using matchboxes with thread to build a simple telephone. If you want other than line-of-sight then it would need to be RF.

Easy steps for making a line following robot using Infrared LED, How to assemble infrared music transmitter and receiver DIY kit September 1, The preferred power supply for the circuit is 6V or above but the circuit also works with regulated 5V from IC not shown in the diagram. As you can see the circuit is very simple and can be easily built over a breadboard. Initially you can experiment with the circuit by blowing air into the microphone and check if the speaker produces some noise.

Log into your account. Reference design for Laser Drive Applications 6 December The complete circuit diagram of this Intercom Project is given below.

Quote of the day. So the microphones and the loudspeakers should not face each other.

For example, if the emitter of T1 is connected to the ground, the value of R12 could be as low as 1 kilo-ohm usually, the range is ohms to 4. Apr 26, 2. To make the project more attractive you can use long wires to increase the distance between the set-1 and set-2 microphone and speaker. Lm38 low cost LM based Audio Amplifier is available on www. Well basically i want it one sided only 1 transmitter and intdrcom receiver and for starters about 5m apartwhat should i do?


Simple Two Way Intercom Circuit Diagram

I just used a normal wire for demonstration and the set-up looks something like this below: Here we have used a capacitor of 10uF to get the maximum gain of 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.

Do you mean you want to talk in only one direction? The complete circuit is built on a bread board, and is powered by a 9V battery. Transistor T1 BC is low-noise and high-gain type.

How to use a relay November 15, Can you Give me the Reason Why!!! Building a circuit on a breadboard November 8, You can also upgrade this project by adding another SPDT switch to turn of the speaker on your side when you are talking. Intercom circuit using lm Reply to Thread. In this circuit we are going to build a very Simple Intercom Circuit using which you can communicate two ways locally within your house or school.
