Hey guys, im trying to control a servo through an 433MHz RF link.
the code:

 #include <ServoTimer2.h>
#include <VirtualWire.h>

#undef int
#undef abs
#undef double
#undef float
#undef round

ServoTimer2 servo;

int i = 0;
void setup()
{
    Serial.begin(9600);   

// Initialise the IO and ISR
    vw_set_ptt_inverted(true);    // Required for RX Link Module
    vw_setup(2000);                   // Bits per sec
    vw_set_rx_pin(0);           // We will be receiving on pin 23 (Mega) ie the RX pin from the module connects to this pin.
    vw_rx_start();                      // Start the receiver
    servo.attach(A2);
}

void loop()
{
    uint8_t buf[VW_MAX_MESSAGE_LEN];
    uint8_t buflen = VW_MAX_MESSAGE_LEN;

    if (vw_get_message(buf, &buflen)) // check to see if anything has been received
    {
    int i;
     // Message with a good checksum received.
        
    for (i = 0; i < buflen; i++)
    {
        Serial.print(buf);  // the received data is stored in buffer
        }
    Serial.println("");
     }
     else if(buf == 1){
       servo.write(0)d
       delay (50);
     }
     else {
         servo.write(875);
         delay(50);
       }
  //else if(buf == 1){
   // servo.write(0);
  //}
  //else if(buf == 0){
    //servo.write(1750);
  //}
  
}

But when i i upload the code to the boarf the servo dosent respond all the time. but the serial print does. can anynone see and error with the code?
Thanks in regards

Code:

    for (i = 0; i < buflen; i++)
    {
        Serial.print(buf);  // the received data is stored in buffer
        }
    Serial.println("");
     }
     else if(buf == 1){
       servo.write(0)d
       delay (50);
     }
     else {
         servo.write(875);
         delay(50);
       }
  //else if(buf == 1){

This is junk. Specially the buf==1 part.
Also, a delay of 50 ms doesn't give your servo to move very far.

dunno why it put a d in there. its not in my code :/
and the buff == 1 should be buff == 1

but ill try and change the delay (:
