LED chasing circuit using micro-controller AT89C2051:
Function:
This project turns on the LEDs connected to port 1 of the micro-controller in sequence, resulting in the chasing LED effect. The data is displayed with one second delay between each output pattern. The following figure shows the output pattern of the LEDs. (There are only 8LEDs).
The following figure shows the circuit diagram of the LED chase project. For a better appearance, you can also organize these LEDs in a circular or any geometric shape with different colors for a colorful output.

LED chasing circuit using AT89C2051 microcontroller Description of the program:
The program is required to load a 1 into the upper (or lower) bit of a variable and then change the data to the right (or left) by a digit and display on the LEDs. A delay is required between each output to see the effect of chasing.
