Turn wireless led

Projects General Guidance
1

Hey,

Can someone point me to a code on how to light up an LED wirelessly. I am using 2 transceiver connected to 2 separate arduino pro mini boards.
Using nrf24l01

Pin 2 on board 1 push button

Led light on pin 6 on board 2

I push button 1 ,led should turn on on 2

rf24 library included.

thanks

But the way i tried maniac examples but couldnt make sense of it .

I also installed 10UF on nrf24l01 and it blew it - the plus minus correctly soldered.
as recommended for noise .. any ideas why ??

Rest assured, if anyone who views a thread has anything to say, they'll say it.

Rule number 1.... post your code and schematics so far

The connexions I'm using in both arduinos are:

RF24 Arduino
GND GND
3V3 3V3
CE 9
CSN 10
SCK 13
MOSI 11
MISO 12

Arduino1 push button on pin2
Arduino2 LED with resistor on pin6

Hi,

Can you please post a copy of your sketch, using code tags?
They are made with the </> icon in the reply Menu.
See section 7 http://forum.arduino.cc/index.php/topic,148850.0.html

Have you looked in the examples section of the IDE?

I have searched all over the place:
TX

#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
#include "printf.h"
int msg[1];
RF24 radio(9,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
int SW1 = 7;

void setup(void){
  Serial.begin(9600);
  radio.begin();
  radio.openWritingPipe(pipe);}

void loop(void){
  if (digitalRead(SW1) == HIGH){
  Serial.println("switch High");
  msg[0] = 111;
  radio.write(msg, 1);
  Serial.println(msg[0]);
}
}

RX

#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
int msg[1];
RF24 radio(9,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
int LED1 = 3;

void setup(void){
  Serial.begin(9600);
  radio.begin();
  radio.openReadingPipe(1,pipe);
  radio.startListening();
  pinMode(LED1, OUTPUT);}

void loop(void){
  if (radio.available()){
    bool done = false;    
    while (!done){
      done = radio.read(msg, 1);      
      Serial.println(msg[0]);
      if (msg[0] == 111){delay(10);digitalWrite(LED1, HIGH);}
      else {digitalWrite(LED1, LOW);}
      delay(10);}}
  else{Serial.println("No radio available");}}

anyone?

What can you read in the Serial Monitor?

it shows actually "No radio available" ,
capacitor is installed on both transceivers.
