19 LED Clock circuit
The clock circuit above uses seven ICs and 19 LEDs to indicate binary coded decimal time. The LEDs can be arranged so that each horizontal group of 3 or 4 LEDs represents a decimal digit between 0 and 9 and...
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...
High-intensity LED Warning Flasher
This circuit is designed as a warning flasher to alert road users to dangerous situations in low-light conditions. It can also function as a bicycle light, adhering to traffic regulations. White LEDs are recommended for use as a front bicycle...
New Knight Rider LED Board
The TL082 (Or a TL072 also is OK) Creates an Adjustable Sawtooth Generator. (It also has a Square wave Output, but it isn`t used here.)
The Left and Right LEDs are connected in series, and if this circuit is used on...
led light flasher
When the preset is set to its maximum, the LED flashes approximately every half second. This flashing rate can be increased by using a larger capacitor value, for instance, changing from 10µF to 22µF will result in a flashing rate...
Flashing-LED Battery-Status Indicator Circuit
A battery-status indicator circuit is useful for monitoring portable test equipment and similar devices. LED D1 flashes to attract the user's attention, signaling that the circuit is operational, preventing it from being left on unintentionally. The circuit produces approximately two...
White LED Flood Lamp circuit
This white LED light illuminates the porch with cool white light. The circuit features a simple and energy-saving design. Its current consumption is practical.
The white LED light circuit is designed to provide efficient illumination while minimizing energy usage. The primary...
LED CHASER Sequencer
All LED negatives are connected to the "COM" pad, then through a 220 Ohm resistor to ground. There is no need for additional current limiting resistors, even with supply voltages up to 16 volts.
The described circuit employs a simple yet...
Flashing Heart circuit diagram
When power is applied to the circuit, all Red LEDs will flash on and off simultaneously. The Yellow LEDs will also flash, but only every other Yellow LED will be illuminated at any given time. The Green LEDs will remain...
