And welcome to the forum. The first question is have you charged the scooter yet? Not only does it full up the batter. Which could be the problem but others have found that it changes the scooter settings. You can find a charger pretty cheap on Amazon. Look through the forum a few have been listed before. Check the battery output voltage. Full is about 42 volts.
The second is are you really sure the wires are correct, I would go through the wires again and make sure they are in the correct locations. And on the right pins of the Arduino. The best method is to power the Arduino off USB, thus taking power out of the equation. All you really need to test the scooter is the Tx line, enable line pulled high to 3.3V- 5.0v and ground.
The last is that some off the plugs have different color coding than what is listed here. So what you do is switch some off the wires around. As long as ground (Black) is always to ground and the battery line (Red) are not changed one combination should work.

I must be most unfortunely man in this forum.
I tried with all file/codes that I found here.
I tried with 3 arduinos
I tried to program arduino with WIN7 and WIN10
I tested the cable, blue 3v3, gren TX, power suppply direct to the arduino board from LM2596 to GND Vin 5V.
And my scooter doesn't wake up....... the display is off and whell blocked..................
If I measure on display and is not power supply from board 0V
My scooter is Es-200b.
What more can I do?
Thx to all for your help
