5-segment Bar Graph LED

/*
This code sets the LED pins as outputs using the pinMode() function in the setup() function. In the loop() function, each LED is turned on in sequence using the digitalWrite() function with a delay between each LED.

After all LEDs are turned on, they are turned off in sequence with the same delay using digitalWrite(). This sequence repeats indefinitely.

Note that the specific pinout and segment mapping may vary depending on the manufacturer of your Bar Graph LED. You should refer to the datasheet or product documentation for the correct pinout and segment mapping for your device.
