Hi, thank you for those of you who answered me earlier. Now, I want to know how to make Servo library work with VirtualWire, or RadioHead Library without needs of processors. Thank You

Hi,
I am using the CDR03A receiver to receive the serial signal from CDT01. I used Serial communication to print the serial out through the tx port, which is hooked up to the data pin on the RF transmitter. For the receiver, I used Serial to read the signal sent from the data pin into the rx pin of the arduino. The code works fine but it seems like the receiver code doesn't receive any signals at all. Please help!
Transmitter code:
int potUp = A0;
int potForward = A1;
int potSide = A2;
int potGForward = A3;
int potGSide =A4;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
pinMode(potUp, INPUT);
pinMode(potForward, INPUT);
pinMode(potSide, INPUT);
pinMode(potGForward, INPUT);
pinMode(potGSide, INPUT);
}
void loop() {
// put your main code here, to run repeatedly:
int valUp = map (analogRead(potUp), 0, 1023, 0, 9);
int valForward = map (analogRead(potForward), 0, 1023, 0, 9);
int valSide = map (analogRead(potSide), 0, 1023, 0, 9);
int valGForward = map (analogRead(potGForward), 0, 1023, 0, 9);
int valGSide = map (analogRead(potGSide), 0, 1023, 0, 9);
Serial.println("$");
Serial.print(valUp);
Serial.print(valForward);
Serial.print(valSide);
Serial.print(valGForward);
Serial.print(valGSide);
}
Reciever Code:
//declaration of integers
int valUp = 0;
int valForward = 0;
int valSide = 0;
int valGForward =0;
int valGSide = 0;
int valWL=0;
int valWR=0;
int WL =8;
int WR=7;
int sideServo = 12;
int upServo = 11;
int downServo = 10;
int forwardServo =9;
#include <Servo.h>
Servo Side, Up, Down, Forward;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Side.attach(sideServo);
Up.attach(upServo);
Down.attach(downServo);
Forward.attach(forwardServo);
pinMode(WL, OUTPUT);
pinMode(WR,INPUT);
}
void loop() {
// put your main code here, to run repeatedly:
char Read = Serial.read();
if (Read == '
)
{
int valUp = map (Serial.read(), 0, 9, 60, 180);
int valForward = map (Serial.read(), 0, 9, 60, 180);
int valSide = map (Serial.read(), 0, 9, 60, 180);
int valGForward = map (Serial.read(), 0, 9, 60, 180);
int valGSide = Serial.read();
int valWL=0;
int valWR=0;
if (valGSide == 5)
{
valWL= 9;
valWR= 9;
}
else if (valGSide <5)
{
valWR =9;
valWL = 9-(valGSide2);
}
else if (valGSide >5)
{
valWL =9;
valWR = 9-(valGSide2);
}
else
{
valWL = 0;
valWR = 0;
}
valWL = map (valWL,0,9,0,255);
valWR = map (valWR,0,9,0,255);
Side.write(valSide);
Up.write(valUp);
Down.write(valUp);
Forward.write(valForward);
digitalWrite(WL, valWL);
digitalWrite(WR, valWR);
}
