Led-peakmeter
The circuit includes a peak detector that immediately drives the readout to any new higher signal level and slowly lowers it after the signal drops to zero. The readout is a moving dot or expanding bar display. The circuit can...
36 Led Flasher Driver Circuit
Originally designed as a three-bell animation circuit for Christmas decorations, this circuit can also be utilized for various other applications that require a flashing effect. By reconfiguring U2 (refer to the data manual), it is possible to achieve more than...
Led circuits
The circuit below illustrates powering one or two LEDs from the 120-volt AC line using a capacitor to drop the voltage and a small resistor to limit the inrush current. Since the capacitor must pass current in both directions, a...
10 Dancing LEDs
The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked up by a small microphone. The expanded version can drive up to ten strips, formed by up to five LEDs each, at...
LED Torch circuit
A common issue with small flashlights is the limited lifespan of both the batteries and the bulb. For example, a typical incandescent flashlight consumes approximately 2 Watts, while the LED flashlight shown in Fig. 1 consumes only 24 mW. This...
1A Low Noise High Current LED Torch/Flash
An ultralow dropout current source maintains accurate LED current at very low ILED voltages. Automatic mode switching optimizes efficiency by monitoring the voltage across the LED current source and switching modes only when ILED dropout is detected. The LTC3216 is...
Fading LEDs schematic
This circuit is used to slowly illuminate and fade a pair of red LEDs (light emitting diodes). The fading LEDs could be installed as 'eyes' in a small pumpkin or skull as a Halloween attraction, or mounted in a Christmas...
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...
bicycle back safety light circuit schematic
This circuit is designed to produce a clearly visible light using 13 high-efficiency flashing LEDs arranged in a pseudo-rotating sequence. Its low voltage, low battery drain operation, and compact size make it suitable for mounting on bicycles as a backlight...
