LED Flasher Circuit
Circuit Operation
The working explanation or circuit operation of this Heart-Shaped Serial LED Flasher circuit is easy and straightforward. Meanwhile, we can associate or connect ten LEDs of red color to IC’s ten yield pins in a heart shape in succession. Everything we simply require to apply pulse heartbeat to the PIN 14.
However, that clock beat is created by 555 timer IC in Astable mode. We can control the speed of blazing LEDs by changing the estimation of Resistors (R1 and RV1) or potentially Capacitor (C1) of 555 timer IC because changing the resistors or capacitors will change the frequency of 555 timers, consequently, it changes the pace of clock pulse. Moreover, we have utilized variable resistor RV1 to shift the clock pulse rate while loading itself. Thus, your circuit is all set to use a decoration piece.
Applications and Uses
Generally, the Heart-shaped serial LED flasher is used as a decoration piece in many events and parties. It is likewise utilized in shop gateways, vehicles, and others.
