Shining Lamp Display Circuit Schematic Diagram

With this circuit, any word can be displayed from the series of 5mm LED. The LEDs has small size and low power. They’re easy to control and arranged according to our wishes. In this the LEDs are arranged to become the word “WELCOME”. IC1 serves as an astable multivibrator, which will trigger IC2. IC2 serves as 10 decoder output, particularly as the LED controller. The IC1 output frequency is 1 Hz. This value can be adjusted by turning the VR1 potentiometer.
