Ten Road string lights flashing circuit

The digital integrated circuit consists of a controller for a string of ten road flashing lights, which drives the El-El0 string lights in a flashing cycle. The system utilizes a ten-count decoder, specifically the CD4017 digital integrated circuit. When a pulse is input at the counting terminal, the output terminals Q0 - Q9 sequentially switch to a high state, activating the thyristors VT1 - VT10. This results in the lights El - El0 illuminating in a cycle, creating a visual effect of movement. The string lights, which may consist of beads, are arranged in compliance with certain regulatory standards to produce various visual effects. The clock pulse generator is built using an A1 (CD4060) and two H NAND gates. The output from these gates generates a square wave oscillator that produces an astable oscillation pulse. The frequency of the oscillation is adjustable via a potentiometer (R1), allowing for control over the flashing rate of the string lights El - E10. The circuit requires a 4.5V power supply and utilizes MCR1.0 type thyristors for switching, along with other basic components that do not have special requirements.

The circuit operates by generating a series of clock pulses that are fed into the CD4017 decade counter. Each pulse corresponds to a counting sequence, where the counter outputs a high signal sequentially from Q0 to Q9. This output is connected to the gates of the thyristors VT1 through VT10, which are configured to allow current to flow through the string lights when triggered. The design ensures that only one thyristor is activated at a time, resulting in a sequential lighting effect that creates the illusion of movement along the string of lights.

The clock pulse generator is critical for the operation of the circuit. The CD4060 IC serves as the primary oscillator, producing a square wave output that is fed into the NAND gates to create the necessary pulse train for the CD4017 counter. The frequency of the output can be adjusted using the potentiometer R1, allowing for fine-tuning of the flashing speed of the lights. This feature is particularly useful for applications requiring specific timing or visual effects.

The thyristors (MCR1.0) are selected for their ability to handle the current required by the string lights while providing reliable switching performance. The circuit's design does not impose strict requirements on the other components, allowing for flexibility in component selection as long as they meet the necessary electrical specifications.

In summary, this digital integrated circuit effectively manages a string of flashing lights through a combination of a decade counter, a clock pulse generator, and thyristor switching, resulting in a visually appealing lighting display that can be customized for various applications.Digital integrated circuit is composed of ten road flashing lights string controller that drives El- El0 ten road string lights flashing cycle.
