TomGeorge:
Hi,
If you use the other example with some LEDS and current limit resistors you will get a better idea of your Lidar working with your Mega.
Other examlple;

Please note note 5;
Supplies plural, I assume a separate supply for the sweep motor.

I did try with leds but then I see only the TX pin is sending a signal. But nothing is coming back on the RX pin.
So I send a signal to the RPLADAR but I dont get anything back. I stil need to try to add more powersupply. Thank you for your help.
