I buyed a new board today and the issue is still same so It must be coding issues.

I don’t think many people reading this topic thought that a new NodeMCU and motor shield would produce a different result.

Did you ever remove the cover over the front steering and work out whether it was a servo or motor?
Did you try monitoring the voltages on the output pins of the shield, running a demo sketch etc?

No I haven’t tried yet.ok would do that.
Front is the motor not servo.

I ordered Arduino shield today.can anyone could help me with the code so I could get it work with blynk.

Well, that’s a step backwards - especially if you want to use it with Blynk.
