This circuit is a sound activated switch.After making a sound you can switch off this circuit.If you want to switch on this circuit after the sound use a relay for that.(That means When the relay switch on the circuit will switch off And when the relay switch off circuit will switch on)
Note
# This circuit operates with 3V power supply
# build this on a PCB
what kind relay we r actually using in this, plzz give me the name & name specifications of the relay and what is s1 actually ?
ReplyDeletes1 is a micro switch.You can use any types of 3V relay for this.
ReplyDeleteI am having trouble understanding the action of the switch. A voice command activates the switch from off to on. A physical reset then sets it back to off, correct.
ReplyDeleteyes yes ,normally after making a sound this circuit goes to on position to off position but if you want to change it as off to on you can use a relay for that.
ReplyDeleteWhat is M1 in the circuit??
ReplyDeleteand what is the application of this circuit?
what is m1 and s1 please explain clearly, and also how can we find that switch is off or on positions and what rating of load should be connected like small leds so that if it turns off by sound then led gets turned off..please reply
ReplyDeleteM1 is the mic and s1 is the main switch you can attach the relay to here as a switch.
