Light control automatic energy-saving LED lights circuit
The circuit is depicted in Figure 1, while the electrical schematic diagram is presented in Figure 2. The AC voltage of 220V is reduced by components C3 and R3. The diodes VD1 and VD2 rectify the voltage, and capacitors C2...
LED Flasher Using Transistor
This simple LED flasher circuit will alternately turn ON and OFF two LEDs. The first LED will illuminate when the second LED is OFF for a certain duration, and then the process will repeat.
The LED flasher circuit operates using a...
28 LED Clock Timer Circuit
A programmable clock timer circuit that utilizes individual LEDs to indicate hours and minutes. Twelve LEDs can be arranged in a circle to represent the twelve hours of a clock face, while an additional twelve LEDs can be arranged in...
led workbench lighting
A highly practical workbench lighting unit designed for electronics hobbyists. The portable inspection lamp circuit features an onboard voltage regulator and a high-brightness 5mm white LED. It can be powered by any 9 to 18 volt DC-rated AC mains adapter...
28 LED Clock Timers
This is a programmable clock timer circuit that utilizes individual LEDs to indicate hours and minutes. Twelve LEDs are arranged in a circle to represent the 12 hours of a clock face, while an additional 12 LEDs are positioned in...
High-intensity LED Warning Flasher
This circuit is designed as a warning flasher to alert road users to dangerous situations in the dark. It can also serve as a bicycle light, subject to traffic regulations and legislation. White LEDs are recommended when the circuit is...
508A microcontroller can deliver a maximum of 25mA
A typical device that requires less than 5v and draws less than 25mA is an LED. A LED must be supplied with an exact voltage for it to operate correctly. Because it requires LESS than 5v, a dropper resistor (current...
Circuit Diagram for a 12V LED Lamp
The color of the LED makes a significant difference. The type and size of the LED, such as 3mm or 5mm, and the power source are crucial factors to consider. More information is required for accurate calculations. A basic electrical...
Current Mirror for LEDs
A Meanwell LED driver rated at 27V and 2300mA is available for use, intended to power two parallel strings of six LEDs each. The question arises whether to maintain the existing circuit with the same component values or to adjust...
