Sorry I don’t quite understand,into the arduino I have already initialized the lamp and the PIR Sensor

You don’t need it,Thanks for feedback

Could you let me know in which line code it showed the error ?

For this, you have to modify the code of the transmitter and receiver.

It's done, Thank you for your feedback.

Thanks for your feedback,according to your question you don't have to declare the LDR as input,But you have to declare the value of the LDR as I did (int value_ldr = analogRead(A4) )
