Hi m.fariz,

Could you share a few clear photos/video of your hardware setup?

Hi,

With Arduino Mega, your choice with UART is only hardwareSerial with D0 and D1, softwareSerial with D10, D11, D12 or D13. Please check with your UART Jumper selection. You can also check related information at here.
