LED VU Meter with LM3914N
The circuit utilizes an LM3914N bar graph display driver (IC1) to control up to ten LEDs. It is configured such that when 0V is applied to the input, only the first LED indicator lights up. This straightforward peak reading VU...
How to connect LED's directly to MAINS
A LED is defined as "light-emitting diode: diode such that light emitted at a p-n junction is proportional to the bias current; color depends on the material used." As the LED is a diode, it doesn't conduct electricity in both...
Alternating-led-flasher
The alternating LED flasher is a two-transistor oscillator with LEDs connected to the collector of each transistor, allowing them to light in sync with the circuit's oscillations.
The alternating LED flasher circuit utilizes a two-transistor oscillator configuration, which is a fundamental...
LED dimmer circuit
Typical segment display LEDs consume around 25 mA for each segment and should be limited to this current with resistors. For a six-digit display to be current limited, at least 42 series resistors are needed. The brightness of the LEDs...
12V Speed Controller/Dimmer
This circuit functions as a speed controller for a 12V motor with a continuous rating of up to 5A or as a dimmer for a 12V halogen or incandescent lamp rated up to 50W. It adjusts the power to the...
NightRydazz
The device is designed to be mounted on the back wheel of a bicycle. It operates using a lithium-ion battery, allowing it to function independently while being attached to the spokes of the rear wheel. All components, with the exception...
A linear dimming controller
An AC voltage of 30V is rectified. The positive terminal is connected to a fuse and a 100W bulb, while the negative terminal is connected to a thyristor. A Zener diode provides a stable bias voltage. A variable resistor (VR)...
Led Expanded Scale Voltmeter Circuit
A10-V zener diode is utilized to extend the measurement range of a voltmeter from 0-5 V to a range of 10-15 V. An LED bar graph illuminates one segment for every 0.5 V increase above 10 V. Additionally, the 7805...
Linear MOSFET voltage regulator
The circuit is a MOSFET based linear voltage regulator with a voltage drop of as low as 60 mV at 1 ampere. Drop of a fewer millivolts is possible with better MOSFETs having lower RDS(on) resistance. The circuit uses a...
