hi
i don't know how to combine this sktches
i have 4 sketches and combine them into 2 code
(one in the sender arduino and other in the receiver arduino both wired to canbus mcp2515 )
ther first sketches is for controlling the leds by push buttons and their brightness by the potentiometer
and the seconds are for displaying the temperture and humidity on oled from a dht11
sender code
sketch1

#include <SPI.h>
#include <mcp2515.h>   
#define potPin1 A0
#define potPin2 A1
#define CS 10

int push2 = 3;
int flag = 0;
int s;
   int potValue1;
   int potValue2;
struct can_frame MyMsg;
MCP2515 mcp2515(CS);
void setup()
{
  while (!Serial);
  Serial.begin(9600);
 SPI.begin();
 mcp2515.reset();
 mcp2515.setBitrate(CAN_500KBPS, MCP_8MHZ);
 mcp2515.setNormalMode(); 
 pinMode(push1, INPUT_PULLUP); 
 pinMode(push2, INPUT_PULLUP); 
 MyMsg.can_id = 0x30; 
 MyMsg.can_dlc = 3; 
}
void loop()
{
 if(digitalRead(push1) == 0) 
 {
 while(digitalRead(push1) == 0);
 s = 1;
  potValue1 = analogRead(potPin1);
        Serial.println(potValue1);
  potValue1 = map(potValue1,0,1023,0,255);
 flag = 1;
 }
 if(digitalRead(push2) == 0) 
 {
 while(digitalRead(push2) == 0);

   potValue2 = analogRead(potPin2);
        Serial.println(potValue2);

 }
 if(flag == 1) 
 {
 flag = 0;
 MyMsg.data[0] = s;

 mcp2515.sendMessage(&MyMsg);

 delay(20);

thank you in advance

You need to write a new program that does what you want. It is OK to copy parts of other programs into the new code as long as

  1. those parts do exactly what you want, in the correct order

  2. don't conflict with any other parts of the code, especially variable names and types, and program functionality

Be sure there is no pin conflict between codes.

Look at any program. they are all similar. at the top, you include the libraries. then you declare the variables. after that you write the functions. at the bottom, you have void(setup)

divide the code being added as noted above. include the libraries you need to add, insert the new variables you need, changing any that conflict with the existing code. paste in the new functions. add the necessary steps to void(setup)

it is a case of sorting apples from oranges, and sending the components of the incoming sketches to where they belong.
