Transistor q1 is used in common emitter mode. 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.
Clap Switch
Clap switch circuit diagram using transistor. 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. Construction of clap switch. It switches onoff a white led or electrical appliances through claps. The circuit can sense the sound of claps from a distance of 1 2 meters. Condenser mic picks up sound vibrations c by the clap.
Clap on off switch with 4017 ic and bc547 transistor. Clap switch schematic circuit without 555 timer. This is the circuit of a very sensitive clap switch. 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 to on clap to off circuit httpsyoutubeuzi9a5. 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.
Circuit is made by using two transistor in our circuit q2q3. In the above explanations we learned a simple clap activated switch circuit which incorporated an ic for implementing the desired onoff toggling actions. The circuit can sense the sound of claps from a distance of 1 3 meters. 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. It switches onoff electrical appliances through clapsin the circuit i will control a single relay using clap switch. 2 clap switch using transistors or bjts.
Clap switch circuit diagram using ic 555 timer. You can use this circuit concept in many ways to activate sound based project. We have used a microphone which converts sound wave into an electric signal. 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. 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 is an interesting hobby circuit which turns on the lights with a clap sound.
Today we are going to make a simple clap switch circuitthis is a simple clap switch circuit with high sensitivity. This electric signal from the microphone is then amplified by using a transistor q1 as shown in circuit diagram.
