Switch press added – reduced pressure This circuit IC1 is IC op amp circuit connected to an Integrator circuit. Operation of the circuit. When the press switch S1 will have positive current flow from the power supply Through resistor R1 to charge the capacitor C2. As a result the output of IC1, lower voltage to 0 volts. When the switch press switch S2, the voltage output level of IC1 is back. Increase nearly as quickly or until the supply voltage. When the buffer circuit IC1.Therefore, voltage output of IC1 is how much value will be passed to IC2 and the …
This circuit is based on learning of the discharge and charge of the C, which can be used as a timer circuit and can be applied in the off electrical appliances. The application has also put relay instead of LED can be enabled. This circuit is working as video below: When you click the switch S1 will cause LED1 light told state ready to run S2 is a timer switch. On press switch S2 current will flow to the C1 charge fully. Then to discharge out through R2 to limit current flow to the bias for transistor Q1. Q1 and …
This is simple speaker overload protection circuit. Generally the level of a signal that departs output of sound signal generator the all. The that get fix have standard same score be 1Vrms. But in now audio signal generator the all the that may produce come to exceed limitation standard of the level input of stereo power amplifier. Thus, This is simple speaker overload protection circuit., for protect a part amplifier and a loudspeaker are damaged. From circuit that picture when have input voltage resistor R1 perform current limit preceding still diode D1-D4 , build model Full wave rectifier circuit, for …
Using relay general the majority then to use power supply that have DC Voltage with the value volt that specify on relay. For relay work but , if , we have no power supply that want to feed give relay. This circuit helps to give relay can work. From the circuit uses two power supply from at for come to work give Relay 12V work. The power supply first use 6Volt when feed volt come in touch C1 charge take keep. The power supply that 2 use voltage more than 3V feed come in the way input make Q1 work. …
If you get into trouble about the heat of notebook. Today I begs for to advise the way enhances the speed of the electric fan with Fan Speed over Ride Switch circuit. Normally the electric fan will begin to turn when 60 c temperatures by have voltage feed 2.0 v. If still hot again enhance voltage go to 2.1,2.2,2.3….3.0V. At 80c circuit temperatures board circuit send the maximum score only. But temperature still go up again arrive at 100c until shutdown by oneself finally. When try wire for electricity usb 5V as a result make the electric fan turns well. …
