The circuit can sense the sound of claps from a distance of 1 2 meters. Clap switch is an interesting hobby circuit which turns on the lights with a clap sound.
Two Clap On Clap Off Circuits 555 Ic 4017 Ic 3 Steps
Clap switch circuit diagram using transistor. We have used a microphone which converts sound wave into an electric signal. Share on tumblr this clap switch circuit using ic 555 is a hobby circuit makes led to glow while you clap or make louder noise. To make the same circuit as mentioned above without ic 555 timer we will have to use the following basic electronic components and devices. Clap switch circuit diagram using ic 555 timer. This electric signal from the microphone is then amplified by using a transistor q1 as shown in circuit diagram. This is the circuit of a very sensitive clap switch.
2 clap switch using transistors or bjts. This construction will give mono pulse when trigger received from mic the duration of pulse time varies respect to r2 and c2 connected with ic555. Today we are going to make a simple clap switch circuitthis is a simple clap switch circuit with high sensitivity. If you want to design a switch circuit to turn on and turn off without reach a physical switch then try this simple clap switch circuit with relay this circuit is designed with timer ic 555 dual d flip flop ic 7474 and a electromagnetic relay. It switches onoff electrical appliances through clapsin the circuit i will control a single relay using clap switch. Construction of clap switch.
Circuit is made by using two transistor in our circuit q2q3. Condenser mic picks up sound vibrations c by the clap. 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. The present design uses a different principle and utilizes only transistors for the above triggering actions. Hello friends today in this video ive shown how to make a simple clap switch using only transistor. The circuit can sense the sound of claps from a distance of 1 3 meters.
You can use this circuit concept in many ways to activate sound based project. Transistor q1 is used in common emitter mode. In the above explanations we learned a simple clap activated switch circuit which incorporated an ic for implementing the desired onoff toggling actions. Clap to on clap to off circuit httpsyoutubeuzi9a5. It switches onoff a white led or electrical appliances through claps. Clap on off switch with 4017 ic and bc547 transistor.
In a flip flop circuit at a time only one transistor conduct and other cutoff and when it gets a trigger pulse from outside source then first transistor is cutoff and 2nd transistor conducts thus output of transistor is either logic 0 or logic 1 and it remains in one state 0 or 1 until it gets trigger pulse from outer source. Clap switch schematic circuit without 555 timer.
