Home Made Circuits and Schematics

There are several methods to measure the current flow and we are about to use Hall effect in our Current sensor switch circuit A LED was added as an indicator in the above circuit diagram you might also use relay provided sufficient power to drive plz check the circuit diagram for detail. now coming to my problem that at second stage where i used transistor as a switch, actually transistor is not working as a switch. the led shown there must be ON/OFF but its nor happen here. when i changed pot Circuit diagram of the smart notification system using RPi is shown in Fig. 2. Hardware includes Raspberry Pi, Android phone, PIR sensor, reed switch, NTC thermistor, doorbell and a few other components. The PIR sensor connected across CON1 detects the And we have also taken the ambient light level into account; when it is dark you won’t be able to read the display so it is only logical to turn the switch off, even if the time delay hasn’t passed yet. The circuit is quite straightforward. For the These circuit diagrams are like maps of the underground: They show you every connection clearly but have very little resemblance to the way things look or connect in the physical world. Take a look at a basic light switch circuit made up of four components In this photo Instructable I will give you a brief introduction to Snap Circuits. You'll learn how to build a simple circuit, to understand Direct Current (DC), and how an electric switch works color with easy to follow diagrams to assemble the .

Circuit diagrams like the one below are used to illustrate a circuit’s different components, or parts, and the direction of its current: A switch in a circuit is any component that can open or close the circuit loop. You can simulate a switch by An open switch is generally represented by providing a will be frequently used throughout the remainder of Lesson 4 as electric circuits are represented by schematic diagrams. It will be important to either memorize these symbols or to refer to this The typical star-delta control circuit wiring diagram in the CAD drawing below will help you which interchangeably execute star-delta motor connections. Pushing the ON switch causes the motor to start running from the star connection to the delta In general practice the diagram to the right is most often used, and is a good guide for wiring a new 4 way switch circuit. When wiring in the 4 way switch it is most simply described as simply cutting the two traveler wires (the two wires that go between .
