Summary

This circuit is a simple digital counter using a 74HC93 4-bit binary counter IC, a pushbutton for clock input, and four red LEDs to display the output. The circuit is powered by a power supply. The pushbutton is used to increment the counter, and the LEDs display the binary count.

Component List

1. 74HC93: A 4-bit binary counter IC.
2. Power Supply: Provides the necessary voltage and current to the circuit.
3. Pushbutton: Used to provide clock pulses to the counter.
4. LED: Two Pin (red): Used to display the binary output of the counter.
