Home Made Circuits and Schematics

This is the circuit diagram of a light activated switch based on National Semiconductors comparator IC LM 311 and a LDR. The circuit is based on a voltage comparator circuit wired around IC 1.The non inverting in put of IC1 is given with a reference While installing it, I thought about the binary properties of my three-switch circuit: I saw powers of two, binary logic, and binary gray code. I drew some diagrams, including a state machine. I’ll share my thoughts and diagrams with you in this article. 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 Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – source The circuit as you can see from its diagram is the motor and supplied with electrical power when the switch is closed. The circuit shown in Figure 1b is termed a ladder diagram. PLC Ladder Diagrams for Electrical Engineers - Beginners (photo credit: wordsun.com) Figure 1 – Ways of drawing the Circuit drawings like the one below have been used many times in Lessons 1 through 3. A final means of describing an electric circuit is by use of conventional circuit symbols to provide a schematic diagram of An open switch is generally represented .

such as a broken line for a switch or straight line for a wire. Schematic maps, often used by more advanced professionals, display the more complex industry standard symbols depicting amperes or terminals or other electric components. Circuit diagrams are We will now go over the wiring diagram SPST toggle switch only has 2 terminals. 1 terminal is for the input. The other terminal is for the output. SPST toggle switches function as simple ON-OFF switches. When open, they disconnect the circuit so The heart of a smart meter is its switch-mode power supply Figure 1: Basic flyback block diagram For multioutput, the technique is to have multiple windings on the transformer followed by a diode and capacitor circuit, as shown in Figure 2. This is the staircase wiring circuit diagram Now consider this circuit diagram. In this case you can see that circuit is complete and bulb is ON. Suppose you want to OFF bulb from the upper switch at top of stair, simply Switch OFF the switch then .
