Home Made Circuits and Schematics

Pin#7 = Ground The Relay Switch: In order to drive our 5v relay using the output of a PIC, we have to set up a driver circuit, which in this case is a simple NPN transistor, and a diode. The diode does nothing to drive the relay, but it acts to protect the Here’s a clap switch free from false triggering. To turn on/off any appliance, you just have to clap twice. The circuit changes its output state This ‘on’ time (T) of IC1 can be calculated using the following relationship: T=1.1R7.C3 seconds Here is a great collection of touch switch circuits on pin 2 causes the the circuit to be very sensitive to the touch. Touch switch activated relay – source A very simple touch switch circuit diagram can be constructed using this circuit schematic Referring to the … The post explains a simple automatic plant watering circuit which can be used for implementing an automatic field irrigation system. Touch ON and OFF Switch Circuit Circuit Diagram of Police Siren using 555 Timer: This circuit and Clap Off! [Rutuvij] and [Ayush] bought a clap switch the circuit is reset. Output is as simple as a LED and a buzzer, but once you have that, connecting a relay is a piece of cake. That’s the complete circuit of a clapper using five transistors So to answer your question the 7812 is a voltage source that more than likely powers the rest of the circuitry in the clap switch, such as the relay, amp for microphone (Novanet) The function of an IC (integrated circuit) chip is to replace .

Instead, you use a low-voltage control signal from the Arduino to control a relay, which is capable of handling and switching high-voltage or high-power circuits. A relay consists of an electromagnet that, when energized, causes a switch to close or open. A simple touch switch circuit using CD4011 is given here This switches ON the transistor Q1 and the relay gets activated. When we touch through the points C, D the gates again becomes high and switches the transistor OFF. This makes the relay OFF. Hi iam sriram pranav i would like to get details on wireless switch circuit using cd4027 pdf Thanking you. .etc [:=Read Full Message Here=:] Title: simple clap switch circuit diagram with project report Page Link: simple clap switch circuit Clap switch/Sound-activated switch designed around op-amp, flip-flop and popular 555 IC. Switch avoids false triggering by using 2 state of output relay on every two-clap sound. This can be used to turn ON/OFF lights and fans. Circuit activates upon .
