Hey everyone, I'm at the final step of this part of a project. Im following the basic structure of this: https://howtomechatronics.com/tutorials/arduino/arduino-wireless-communication-nrf24l01-tutorial/
My receiver can receive the data from button1, but when I open up the serial monitor I just get the empty squares as the data being received. ""
Basically when I switch from high and low on pin 6 on the transmitter, I just want the servo to turn from 180 to 0 degrees on the receiver.
Thank you for your time.
Here are my codes:
Transmitter
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
RF24 radio(7, 8); // CE, CSN
const byte addresses[][6] = {"00001", "00002"};
boolean buttonState = 0;
int button1 = 6; //button pin, connect to ground to move servo
void setup() {
pinMode(button1, INPUT);
digitalWrite(6, HIGH);
radio.begin();
radio.openWritingPipe(addresses[1]); // 00001
radio.setPALevel(RF24_PA_MIN);
}
void loop() {
radio.write(&button1, sizeof(button1));
}
Receiver
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#include <Servo.h>
#define button 4
RF24 radio(7, 8); // CE, CSN
const byte addresses[][6] = {"00001", "00002"};
Servo servo1;
int press1 = 0;
void setup() {
pinMode(button, INPUT);
Serial.begin(9600);
servo1.attach(2);
radio.begin();
radio.openReadingPipe(1, addresses[1]); // 00001
radio.setPALevel(RF24_PA_MIN);
}
void loop() {
radio.startListening();
if ( radio.available()) {
while (radio.available()) {
int button1;
pinMode(button1, INPUT);
radio.read(&button1, sizeof(button1));
press1 = digitalRead(button1);
Serial.write(button1);
if (press1 == LOW)
{
servo1.write(0);
}
else {
servo1.write(180);
}
}}}
