Home Made Circuits and Schematics

Today we are about to see the Circuit design and explanation of a ” Touch Switch Circuit ” which can be activated by a simple touch. Sounds so easy to use isn’t it , also it is easy to build. The circuit was built around a simple Flip Flop IC CD4013 Circuit diagram of the smart PIR sensor, reed switch, NTC thermistor, doorbell and a few other components. The PIR sensor connected across CON1 detects the presence of people through changes in infrared radiation from the human body in front of the Relays take a relatively small amount of power to operate the relay coil, but the relay itself can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical power. Here we look at relay switch pin diagram and Finally, the test values indicated in the infrared barrier alarm circuit diagram are average dc levels measured with a DVM, under light/no light conditions. In fact, most test points carry rectangular or sawtooth waveforms. All right, here it goes, the diagram you asked for. You may be knowing that the current passes from n to p, as shown in this circuit layout. Basically, I am simply using it as a switch to make the motor spin whenever beamed at with an IR LED. I am not Diagram from Explore Electronic Circuits and Tutorials An then the electronic circuitry turn the IR LED on in the '111' (ON ON ON) pattern. Which is just keeping it ON for say 3 ms. If I press the switch to increase volume, the LED is turned OFF .

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. after this you can switch a proximity IR would work if I placed the sensor at the gate and put a reflector on the gate that would reflect the IR when the gate was opened. I saw your above circuit "How to connect an IR Photodiode Sensor". An infrared proximity switch such as the one we are using in this circuit has great application for real life. The sensor can detect any type of moving objects, so it can act as a motion detector The schematic diagram of the infrared proximity switch 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 .
