Hello guys!
So… I am making my final project for this year in school.
I’ve decided to do something using two NRF24L01 modules, but I am having a big problem with the communication between the two of them, it just won’t work!
Here’s what I am trying to do for now, make a led turn on when a push button is pressed, the schematic for the circuits I am using, are those:
The codes I am using are:
Transmiter:
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#define buttonPin1 A0
int buttonState1 = 0;
RF24 radio(9, 10); // CE, CSN
const byte address[6] = "00002";
void setup() {
pinMode(buttonPin1, INPUT);
Serial.begin(9600);
radio.begin();
radio.openWritingPipe(address);
radio.setPALevel(RF24_PA_MIN);
radio.stopListening();
}
void loop() {
buttonState1 = digitalRead(buttonPin1);
if (buttonState1 == 1)
{
buttonState1 = 1;
}
else if (buttonState1 == 0)
{
buttonState1 = 0;
}
Serial.print(buttonState1);
radio.write(&buttonState1, sizeof(buttonState1));
}
Receiver:
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
int LED = A1;
int buttonState = 0;
RF24 radio(9, 10); // CE, CSN
const byte address[6] = "00002";
void setup() {
Serial.begin(9600);
pinMode(LED, OUTPUT);
digitalWrite(LED, HIGH);
radio.begin();
radio.openReadingPipe(0, address);
radio.setPALevel(RF24_PA_MIN);
}
void loop() {
radio.startListening();
while (!radio.available());
radio.read(&buttonState, sizeof(buttonState));
Serial.println(buttonState);
if (buttonState == 1) {
digitalWrite(LED, HIGH);
}
else if (buttonState == 0) {
digitalWrite(LED, LOW);
}
}
Also, I want to mention that the NRF24L01 I am using, look like this:
I’ve tested the push button with the serial monitor, it’s working and the led is turning on.
But when I try to turn on the led with the button, it just doesn’t work, nothing happens… what could it possibly be?
Please help me!!
