KC868-A4 Bluetooth momentary Switch - franco.demei@gmail.com - 04-27-2024
I'm trying to program four momentary switch via bluetooth commands. I don't understand why I can't enable "Relay3".
To compile KC868-A4 code I'm using "Arduino IDE". To program Android code "MIT App Inventory" .
Here is the codes I Used. Can some one help me to understand where is a mistake ? Tank You.
AI Code
Arduino IDE Code:
#include "BluetoothSerial.h"
BluetoothSerial SerialBT; // RX | TX
int Relay1 = 2;
int Relay2 = 5;
int Relay3 = 15;
int Relay4 = 4;
void setup() {
pinMode(Relay1, OUTPUT);
pinMode(Relay2, OUTPUT);
pinMode(Relay3, OUTPUT);
pinMode(Relay4, OUTPUT);
Serial.begin(19200); // Serial monitor
SerialBT.begin(19200); // Bluetooth serial communication
Serial.println("Bluetooth Control for KC868-A4 Relays");
}
void loop() {
if (SerialBT.available()) {
char command = SerialBT.read();
// Command format: '1' to '4' for relays 1 to 4
if (command >= '1' && command <= '4') {
int relay = command - '1' + 2; // Calculate the relay control pin
digitalWrite(relay, !digitalRead(relay));
Serial.print("Relay ");
Serial.print(command);
Serial.print(" is ");
Serial.println(digitalRead(relay) ? "ON" : "OFF");
}
}
}

this is KC868-A4 relay control by bluetooth arduino demo code, you can test it: https://www.kincony.com/forum/showthread.php?tid=1647

I solved in this way:
Code:
#include "BluetoothSerial.h"
BluetoothSerial SerialBT;
#define Key1 36
#define Key2 39
#define Key3 27
#define Key4 14
#define RELAY1 2
#define RELAY2 15
#define RELAY3 5
#define RELAY4 4
int incoming;
void setup() {
pinMode(RELAY1, OUTPUT);
pinMode(RELAY2, OUTPUT);
pinMode(RELAY3, OUTPUT);
pinMode(RELAY4, OUTPUT);
pinMode(Key1, INPUT);
pinMode(Key2, INPUT);
pinMode(Key3, INPUT);
pinMode(Key4, INPUT);
Serial.begin(19200); // Serial monitor
SerialBT.begin(19200); // Bluetooth serial communication
Serial.println("Bluetooth Control for KC868-A4 Relays");
}
void loop() {
ScanKey1();
ScanKey2();
ScanKey3();
ScanKey4();
if (SerialBT.available()) {
char command = SerialBT.read();
// Controlla il comando ricevuto e attiva o disattiva il relè corrispondente
switch(command) {
case '1':
digitalWrite(RELAY1, HIGH);
break;
case '2':
digitalWrite(RELAY1, LOW);
break;
case '3':
digitalWrite(RELAY2, HIGH);
break;
case '4':
digitalWrite(RELAY2, LOW);
break;
case '5':
digitalWrite(RELAY3, HIGH);
break;
case '6':
digitalWrite(RELAY3, LOW);
break;
case '7':
digitalWrite(RELAY4, HIGH);
break;
case '8':
digitalWrite(RELAY4, LOW);
break;
default:
break;
}
}
}
int KEY_NUM1;
int KEY_NUM2;
int KEY_NUM3;
int KEY_NUM4;
void ScanKey1() {
KEY_NUM1 = 1;
if (digitalRead(Key1) == LOW) {
delay(20);
if (digitalRead(Key1) == LOW) {
KEY_NUM1 = 0;
digitalWrite(RELAY1, HIGH);
} else {
digitalWrite(RELAY1, LOW);
}
}
}
void ScanKey2() {
KEY_NUM2 = 1;
if (digitalRead(Key2) == LOW) {
delay(20);
if (digitalRead(Key2) == LOW) {
KEY_NUM2 = 0;
digitalWrite(RELAY2, HIGH);
} else {
digitalWrite(RELAY2, LOW);
}
}
}
void ScanKey3() {
KEY_NUM3 = 1;
if (digitalRead(Key3) == LOW) {
delay(20);
if (digitalRead(Key3) == LOW) {
KEY_NUM3 = 0;
digitalWrite(RELAY3, HIGH);
} else {
digitalWrite(RELAY3, LOW);
}
}
}
void ScanKey4() {
KEY_NUM4 = 1;
if (digitalRead(Key4) == LOW) {
delay(20);
if (digitalRead(Key4) == LOW) {
KEY_NUM4 = 0;
digitalWrite(RELAY4, HIGH);
} else {
digitalWrite(RELAY4, LOW);
}
}

ok, good.
