12V SMPS Driver Circuit for LED Strip
A 12V SMPS Switch Mode Power Supply Driver Circuit is a regulated power source that transforms mains power which is typically 110V or 220V AC, into a steady and secure 12V DC voltage that may be used to light LED strips. We will construct a simple, reasonably priced and potent LED driver circuit in this […]
Simple Flasher Circuit using LED and LDR
An LED and an LDR is used to make this simple basic flasher circuit. This circuit controls the LEDs blinking pattern by taking use of the LDRs ability to change resistance in response to light intensity. Without the need of complicated chips or transistors this device produces the effect of blinking LEDs. Basic electrical parts […]
Simple Automatic Staircase Light Circuit
An automated staircase light circuit is a device that activates the lights on your steps only when someone is using them and automatically switches them off after a certain amount of time. This is an excellent approach to increase home safety and conserve electricity. Circuit Introduction: Regular stair lights: These might be troublesome to turn […]
Simple Motorcycle LED Turn Signal Indicator Circuit
A simple motorbike LED turn signal indicator circuit adds a flashing with chasing effects on the LEDs in place of the conventional incandescent bulbs in the turn signal system. In this circuit IC 555 is integrated circuit acts as an oscillator, generating the flashing signal. Circuit Working: Parts List: Category Description Quantity Wattage Resistors 390Ω […]
Simple Fade On Fade Off LED Circuit
A Fade On Fade Off LED Circuit enables an LED or a string of LEDs to turn on and off gradually rather than abruptly. It is also known as a dimming circuit with fade effect. This produces an effect that is smoother and more aesthetically pleasing. Circuit Working: Parts List: Category Description Quantity Wattage Resistors […]
