We are not mind readers. There is no mention of ‘line follower’ in the first post.

If you want help you need to post a picture of what you are doing (or tell the model of sensor) and also the code you have so far that ‘does not work’ explaining what you expect it to do and what it is actually doing.

i am not able to send own code through that sensor

You do not send code through a sensor. You can not send code through a sensor.

Now can you get someone to translate for you or use another translator please.
