I am making a project and have two codes and need to combine them

@pushkarsaluja2008,

As others have pointed out the use of delay is the main problem in your code. Without a complete re-write to use non-blocking code without delay you are not going to fix this, and certainly not in 1 day. The tutorials you need to understand to re-write your code are on this forum and are commonly referenced for this kind of problem. The ones I suggest are:

This shows you how to handle serial data properly:

Serial Input Basics - updated

Updated Version Please note that this is a revised version of the advice in this earlier Thread which has become very long. As far as possible I have kept the code examples identical or simplifed them slightly. It should not be necessary to refer to the older Thread, but feel free to do so. Contents The following sections are in this Tutorial Introduction Serial data is slow by Arduino standards Example 1 - Receiving single characters Why code is organized into functions Exampl…

This gives examples of using millis for timing, no delays:

Flashing 2 or more LEDs at the same time

Introduction A common question is to ask how to flash 2 (or more) LEDs at the same time. Typically the person asking will be using delay and will be experiencing the main problem with delay: it blocks and stops anything else from happening. The code below flashes 2 LEDs, one connected to pin 2 and one to Pin 3, each with a suitable resistor (220 Ohms or thereabouts) to 0V. Each LED flashes independently of the other. Notes I have used separate functions called from the loop function to illus…

Others might suggest other tutorials, but the point will be the same.

If you really need to finish this today you have to decide what to do, because you are not going to finish this today.
