hi,

Could any one advice me how to fix this code issue.

Thanks

//Transmitter Code (Uno)

#include <VirtualWire.h>

void setup(){

Serial.begin(9600);

vw_setup(2000);
vw_set_tx_pin(7);

}

void loop(){

if(Serial.available())
{
char c = Serial.read();

if(c =='1')
{
vw_send((unit8_t*)c, 1);
}
else if(c == '0')
{
vw_send((unit8_t*)c, 1);
}
}
}

ERROR MESSAGE : 'unit8_t*' was not declared in the scope
