Help with using capacitive touch sensor to turn on and off led strip

Projects Programming
1

I'm new to coding with arduino and I tried combining two different projects to allow a capacitive touch sensor to turn on and off an Led strip. Here is the code:

#include <CapacitiveSensor.h>


CapacitiveSensor   cs_4_8 = CapacitiveSensor(4,8); // 1M resistor between pins 4 & 8, pin 8 is sensor pin, add a wire and or foil

void setup()                    
{
   cs_4_8.set_CS_AutocaL_Millis(0xFFFFFFFF);// turn off autocalibrate on channel 1 - just as an example
   Serial.begin(9600);
   pinMode(7,OUTPUT);
   pinMode(5, OUTPUT);
}

void loop() {
 int i;
 long sensor1 =  cs_4_8.capacitiveSensor(50);

    Serial.println(sensor1);  // print sensor output 
   if(sensor1 >= 400)
   {
    (i = 0; i < 255; i++) { 
    analogWrite(PIN, i);
    delay(FADESPEED);
   }
   else{
    (i = 255; i > 0; i--) { 
    analogWrite(PIN, i);
    delay(FADESPEED);
   }  
 
}

I get this when I try to verify:

sketch_apr10a:19:30: error: expected ')' before ';' token
    if(sensor1 >= 400); (i = 0; i < 255; i++)
                              ^
sketch_apr10a:19:44: error: expected ';' before ')' token
    if(sensor1 >= 400); (i = 0; i < 255; i++)
                                            ^
sketch_apr10a:24:4: error: 'else' without a previous 'if'
    else
    ^
sketch_apr10a:26:13: error: expected ')' before ';' token
     (i = 255; i > 0; i--) { 
             ^
sketch_apr10a:26:25: error: expected ';' before ')' token
     (i = 255; i > 0; i--) { 
                         ^
sketch_apr10a:31:1: error: expected '}' at end of input
 }
 ^
exit status 1
expected ')' before ';' token

(i = 0; i < 255; i++)

Maybe you wanted:

for (int i = 0; i < 255; i++) :wink:

    if(sensor1 >= 400); (i = 0; i < 255; i++)

If statements rarely end with semicolons.

Do NOT put two statements on one line.
