You can adjust the sensitivity how loud of a sound will activate the circuit from a pin drop to a mack truck horn. Working of this circuit is quite simple the main component is an audio amplifier lm386 ic.
Clap Activated Light Circuit Gadgetronicx
Sound switch circuit diagram. The output electric signal from microphone is very weak and need amplification which is done by transistor t 1 and t 2. The discussed sound activated alarm circuit will work with any supply in between 6 and 12 however if the alarm is a powerful one the current might have to be selected accordingly. Tone amplifier sound operated on off switch. In the circuit sound operated on off switch microphone is used as sensor. This circuit is operating on 9 12v dc. Circuit diagram working.
Mic 1 receives tone signal of 46 khz from tone generation or transmitter circuit and converts it into electric signal. Very practical for a variety of projects. A switch is an electronic device that is used to connect or disconnect the power supply to the circuit. This is a project of a sound sensor switch using lm358n ic. A clap switch is an electronic device that works based on clapping action it converts sound energy into electrical pulses and proved these electrical pulses as input to the control circuit for controlling the light. Siris there any circuit diagram u knowthat can turns the house light on when c clap sound is appears n remains constantn also turns d light off with any sound or a clapif u know about dis then plezz make for me circuit diagram for men send it to my e mail d.
The circuit was drawn using fritzing software. The complete circuit diagram for the arduino whistle detector switch circuit using sound sensor is show below. 8 thoughts on sound activated switch ratnadeep march 3 2012. The sound sensor and the relay module is powered by the 5v pin of the arduino. The preset may be used for setting the sensitivity of the circuit. The output pin of the sound sensor is connected to the digital pin 8 of the arduino this is because of the.
Lm358n is a dual high gain opamp ic contains two independent opamp in one package. Also the circuit diagram is at around 418 or just at the end of the video. This circuit amplifies that output and feeds it to a monostable circuit that makes the led turn on for a bit. The ic has a lot of good features due to which it can be used in variety of sensor circuits. Clap switch is an interesting hobby circuit which turns on the lights with a clap sound. Although its name is clap switch but it can be turned on by any sound of approximately same pitch of clap soundthe main component of this clap switch circuit is the electric condenser mic which has been used as a sound sensorcondenser mic basically converts sound energy into electrical energy.
Following are the steps that you should follow to make this circuit work sound is received by an electret mic which converts these sound signals into electrical signals. This is a sound activated switch circuit. Its will turn on and turn off based on a loud sound such as clapping your hands.
