Regulated 24 Watt Broad Spectrum LED
This project involves constructing an energy-efficient broad spectrum LED lamp system designed for indoor reflective room lighting. The lamp provides a broad color spectrum that closely resembles natural sunlight compared to fluorescent bulbs and white-only LEDs. The light output is...
Wireless-fm-microphone
Utilize standard RF wiring precautions. Optimal speech clarity is achieved by employing an electret microphone. For music reproduction, replace it with a dynamic microphone element.
In the design of audio circuits, particularly those involving speech and music, the choice of microphone...
Constant LED power circuit
An LED is usually a series resistor needed to ensure that the LED does not get too much power. The disadvantage of such resistance is that the current through the LED and thus the brightness changes as the voltage changes....
Remote Controlled Fan Regulator EEE Project Report
This report presents a comprehensive overview of a mini project titled "Remote Controlled Fan Regulator," developed in accordance with the curriculum requirements for the sixth semester of the Bachelor of Technology degree in Electrical and Electronics Engineering. The report is...
Puff to OFF LED circuit
This circuit features an LED that can be turned off with a puff of air. A condenser microphone (M1) detects the puff. When the push button switch S1 is activated, transistors Q2 and Q3, configured as a latching pair, are...
Mains Blinking LED
I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of the circuit is extraordinarily...
LED Knight RiderCircuit With 4017 and 555 IC
The following circuit illustrates an LED Knight Rider Circuit Diagram. This circuit is based on the 4017 and 555 integrated circuits. Features include the Knight Rider effect with four LEDs.
The LED Knight Rider circuit is designed to create a visual...
PWM to vary the light intensity of a 220V bulb
A 220V bulb is connected such that one end of the relay is linked to a 220V DC source and the other end is connected to ground. The switching between these two points is controlled by a PWM output as...
Regulated LED Lamp
The LM317L and resistor act as a current regulator set to 40ma. Current flows from the battery through one pair of LEDs, through the regulator, through the other pair of LEDs, and back to the battery. The capacitor filters out...
