2ch servo steering en 3.0

/*  this application allow to control a rear servo with 2ch radio.
before start you need arduino program and driver CH341SER.
radio value are normally 1000 to 2000 center 1500
but before is better check your endpoint with  serial monitor in arduino ide
to check signal void copy it in a new tab this sketc below and check values write in
serial monitor by moving trasmitter wheel or stick


int rxpulse;
void setup() {
Serial.begin(9600);
}
void loop() {
rxpulse = pulseIn(8, HIGH); //-- per sapere qual'è il valore del segnale di sterzo
Serial.println(rxpulse);
}

after you can fill better your sketch with your tx right values signal from front steering
check also your bec because 2 servos sometimes more need power or an external bec.

as is show you have to set your custom parameters in define list
*/
#define antsx 1000 //-- in front servo endpoint sx
#define antdx 2000 //-- in front servo endpoint dx
#define postsx 30//--   out rear servo sx if inverted with postdx it reverse
#define postdx 150 //-- out rear servo dx if inverted with postsx it reverse
#define centro 0 //-- add or subtract xx value to center steering
#define tolerance 5 //-- if your poor quality servo vibrates try 5
#include <Servo.h>

unsigned int rxpulse;
unsigned int newPos, oldPos;
void setup() {
myservo.attach(10); //-- rear servo signal out pin
pinMode(8, INPUT); //-- front servo signal in pin
}
void loop() {
rxpulse = pulseIn(8, HIGH);
newPos = map(pulseIn(8, HIGH), antsx, antdx,postsx, postdx);
if (abs (newPos - oldPos)> tolerance) {
oldPos = newPos;

myservo.write(newPos + centro);
