Receiver Output to Control PWM Value

I need the throttle pin of an R/C receiver to interface with the Arduino and constrain, I believe, between two values. The following code:

int pinArray[] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13};
int count = 0;
void setup() {
Serial.begin(9600);
for (count=0;count<13;count++) {
pinMode(pinArray[count], OUTPUT);
}
pinMode(0, INPUT);

int eraser = 7; //111
TCCR0B &= ~eraser; //sets timers to 000
TCCR1B &= ~eraser;
TCCR2B &= ~eraser;
TCCR3B &= ~eraser;
TCCR4B &= ~eraser;
int prescaler = 1; //1 being highest frequency
TCCR0B |= prescaler; //sets timers to 1
TCCR1B |= prescaler;
TCCR2B |= prescaler;
TCCR3B |= prescaler;
TCCR4B |= prescaler;
}

int x = analogRead(0) / 1023; //percentage of input
int c = x * 10000 + 8000; //range defined

void loop() {
float a = 128.0;
float b = 128.0;
float c;
float d = 2.0;
float e = 18.3; //offset

{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(2,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(3,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(4,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(5,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(6,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(7,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(8,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(9,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(10,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(11,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(12,value);
}
{
int value = a - b * abs(sin(dPImillis()/c));
analogWrite(13,value);
}
}

The analog input pin should be zero, while the PWM outputs are from 2 to 13. Float C is the variable value. Is this:
"
int x = analogRead(0) / 1023; //percentage of input
int c = x * 10000 + 8000; //range defined
"
-all that is required for one channel PPM control?

You have some issues that need to be addressed:

  1. you are dividing by "c" which has not been initialized
  2. you are creating a variable "x" that is an int and dividing analogRead() by 1023, that's pretty much always going to be 0

What board are you using?

I am using a 2560 Mega rev 3.
