Led chaser circuit using Arduino Nano with codes
Requirements
1) Arduino Nano
2) Leds
3)Breadboard
4)Jumper wire
5)Micro USB Cable
The circuit is simple to design. Set the Arduino Nano on breadboard. Connect all the LEDs to digital pins of Arduino Nano.
After connecting LEDs give ground supply to LEDs from Arduino Nano any GND pin.
All LEDs share the common ground.
I have not used resistor here to connect between digital pins and positive terminal of led for protection of led. If you want you can add 450ohm resistor to reduce current flow.
You can also use same code for Arduino Uno to try chaser effect on LEDs.

Circuit Diagram
Steps before uploading code on Arduino board1)Select Board as Arduino Nano in Tools
2)Select processor as Atmega328p (old bootloader ) for arduinno nano board
3)Set Port based on your system provide to Arduino nano in my case port Com5
After all steps verify and upload code on Arduino nano board.
