LOGIC GATES

LOGIC GATES

  LOGIC GATES Logic gates are the basic building elements of any digital system or circuit. The name Logic gate is derived from the sense of the making decisions ability of such a device, and after making decisions it produces one output result. We can say that Logic gates are the fundamental building blocks of any digital circuits or digital […]

Arduino Remote control 220v AC Without Relay

Arduino Remote control 220v AC Without Relay

Remote controlled AC Load With Arduino Without Relay Arduino remote control Here I am presenting a mini project of remote control switch for any AC appliance without Relay. A homemade Arduino Remote control switch is an interesting idea. Arduino Uno board is used here but you can use any Arduino board. Download Arduino Library Proteus  Generally, Coil Relays are used […]

Arduino LM35 temperature sensor with simulation

Arduino LM35 temperature sensor with simulation

Digital thermometer design and development using Arduino UNO and LM35 temperature sensor Arduino LM35 Temperature Sensor with LCD display Thermometers enable us to read the temperature in any room, space or region. Thermometers are widely used in industries for temperature monitoring during the manufacturing process. Similarly, thermometers are of vital importance at hospitals, especially in incubation units. The need of […]

Dark Sensor Circuit

Dark Sensor Circuit

Dark/Light Activated Circuit using LDR The dark sensor circuit is very useful to Automatic Switch ON and OFF any appliance by Detection of Light and Dark. LDR is a photoresistor that is used for the detection of light. When Light intensity high on LDR, The Resistance through it Decrease and When Light intensity is Low on LDR, then the resistance […]

CFL Driver Inverter Circuit

CFL Driver Inverter Circuit

12v CFL Inverter circuit for Emergency Light This is a small power inverter circuit that produces 230v ac at the output through the transformer. The circuit is designed by T.Kalpana. This can be used as the emergency CFL lighting, CFL needs AC input for operating and this circuit provides the AC to CFL. This circuit is very useful for home, […]

Homemade Powerbank using Li-ion 3.7v Battery

Power bank For Mobile/Smartphone What is a Power bank When we go away from home then I face a very common problem, that is power backup of mobile phones. During travelling, it is a very common problem to get regular power backup.  If you’re traveling or out you won’t have a chance to recharge your device, simply plug in your power […]

Solid State Relay With Triac And Optocoupler

Solid State Relay With Triac And Optocoupler

Solid State Relay/ Optocoupler Relay Solid State Relay is a type of switch to activate Load by using without any Mechanical parts. In this there is only semiconductor devices used, no Mechanical coil relay is used to Switching the Connected Load.  Triac is used at the place of coil relay to switch ON and OFF. So this circuit is some […]
