You are really going to need to supply a wiring diagram. It appears that you are trying to use the Serial instance to talk to the RFID reader and the PC at the same time. That's a non-starter.
The code you posted spends one second reading from the speed sensor, then does nothing with the data it read. Why not?
Then, it spends a full second with it's thumb up it's ass doing nothing. Why?
i have attached the sketches with it
You attached ONE sketch.
Sir, i didnt understand your language can u plss tell me
Hey, at least I spelled all the words correctly. That's more than you seem capable of.
