Circuit Diagram

The CD4017 is connected to LEDs on its output pins. The clock pulse drives the sequence of LEDs turning on one by one.

Steps for the Experiment

1. Connect the clock pulse to the clock input of the CD4017.
2. Connect the LEDs to the output pins of the CD4017.
3. Observe the LEDs lighting up in sequence as the clock pulses.

Explanation

The CD4017 is a decade counter that provides sequential high output on its output pins with each clock pulse. This creates the LED sequence.

Results and Observations

• The LEDs should light up sequentially with each clock pulse from the CD4017.
