Here is the code I used for NRF24 with Potentiometer, when I tried running it, I only read one value on the serial monitor. I want to see a varying value whenever I calibrate it using a pot.
See the image attached below for the result I have.
Please correct my code if ever I've done something wrong.
Please help me.
#include <RF24Network.h>
#include <RF24.h>
#include <SPI.h>
int sensorPin = A0; // select the input pin for the potentiometer
int ledPin = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor
RF24 radio(8,53);
RF24Network network(radio);
const uint16_t this_node = 001;
const uint16_t other_node = 000;
const unsigned long interval = 2000; //ms
unsigned long last_sent;
unsigned long packets_sent;
struct payload_t
{
byte senderID;
float sens1;
};
void setup()
{
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
pinMode(sensorPin,INPUT);
Serial.println("RF24 Network Tx-DS18B20");
SPI.begin();
radio.begin();
network.begin(/*channel*/ 88, /*node address*/ this_node);
}
void loop(void) {
sensorValue = analogRead(sensorPin);
Serial.println(sensorValue);
// Check the network regularly
float sizeofpayload;
network.update();
unsigned long now = millis();
if ( now - last_sent >= interval )
{
last_sent = now;
byte senderID = 1;
float sens1 = (sensorValue);
payload_t payload = {senderID,sens1};
RF24NetworkHeader header(/*to node*/ other_node);
bool ok1 = network.write(header,&payload,sizeof(payload));
}
}
I really appreciate you for giving me that suggestion.
But it would be easy for me to use the network that I'm used to. This would be the answer to complete my project.
I hope someone could help me to solve my problem.
Thank you very much.

Yeah sure, I will try work for it if I can, but I also need someone to help me out of this trouble I'm having with my codes.

Hi Clarkton,

Hi Robin,
Yes I'm already done doing that. I already made a small changes on the code. When I tried to remove the NRF24L01 on the circuit, the output is okay, but whenever I put NRF24 back, the result is like the attached image.

Post the code that works and also post the code with the small change. It obviously was not the correct change. (And please list the line number(s) with the change).
Thank you for always responding to my questions.
I already know the problem with my program, after editing some changes on it, it's finally working.
You are always right with your "Two or three hours spent thinking and reading documentation solves most programming problems."
