using led as a light sensor

This circuit demonstrates the use of a standard LED as a light sensor. It utilizes the photovoltaic voltage generated across the LED when exposed to light. LEDs are more cost-effective than photodiodes and feature an integrated filter, which is advantageous...

LED Audio Level (VU) Indicator and Alarm: The Dot Turns to Bar When The Signal Reach The Maximum Le

This LED (Light Emitting Diode) display consists of 10 LEDs to indicate the level of an input signal. If the signal is low, only LED #1 will light up. As the signal level increases, the illuminated dot will progress through...

700 Ma Led Power Supply circuit using Monolithic Controller

Quasi square wave resonant converters, also referred to as quasi resonant (QR) converters, facilitate the design of flyback Switch Mode Power Supplies (SMPS) with diminished Electro Magnetic Interference (EMI) and enhanced efficiency. Due to their low noise generation, QR SMPS...

mains operated led night lamp

This is a simple and effective LED-based night lamp circuit that can be powered directly from a 230V mains supply. The circuit uses a total of 24 white LEDs and produces an output of approximately 15W. The resistor R1 and...

Light emitting diode LED displays the basic structure of the driving circuit

The circuit drives the light-emitting diode in a digital display configuration. The count signal is fed into the ICM7217 chip, which processes the count and subsequently drives the digital display board. The connection between the thumbwheel switches is illustrated in...

simple led automatic daynight lamp

The power supply utilized in this circuit is of the capacitive type, eliminating the need for a transformer and allowing for a compact design that can be easily installed in small spaces. The circuit employs LEDs instead of traditional filament...

Bi-Color Indicator Circuit

With switch SI open, base bias is supplied to transistor Q2 through a voltage divider formed by resistors R2 and R3, which activates the green element of the LED. This indicates that power is being supplied to the project. When...
