Looks like it's working but you are not getting a good connection somewhere. How long are your wires? Do you have a picture of your setup?

Ohh I see, wires are too long I think, Please see picture, I will resolder them and make them as small as possible.

yes wires are too long.
i normally use 10-15cm long wires.
also wires shouldn't be too thin.
