[pongsakorn_pki]

Hi guys I have a question. How in this code it is

Arduino Uno R3 Bluetooth(HM-10 BLE Bluetooth 4.0 CC2540 CC2541 Serial Wireless Module ) Command Push button Switch NO NC (Push NC pull NO) to Open Relay Switch 5
I tried it, but it was not.
I started learning arduino recently

help me Please .. thanks.

const int LED1=3;
const int LED2=4;
const int LED3=5;
const int LED4=6;
void setup ()
{
Serial.begin(9600);
pinMode(LED1,OUTPUT);
pinMode(LED2,OUTPUT);
pinMode(LED3,OUTPUT);
pinMode(LED4,OUTPUT);
}
void loop()
{
if(Serial.available()>0)
{
char x = Serial.read();
if(x=='a')
{
digitalWrite (LED1,HIGH);
digitalWrite (LED2,LOW);
digitalWrite (LED3,LOW);
digitalWrite (LED4,LOW);
Serial.println ("tufreedom11");
}
if(x=='b')
{
digitalWrite (LED1,LOW);
digitalWrite (LED2,HIGH);
digitalWrite (LED3,LOW);
digitalWrite (LED4,LOW);
Serial.println ("tufreedom22");
}
if(x=='c')
{
digitalWrite (LED1,LOW);
digitalWrite (LED2,LOW);
digitalWrite (LED3,HIGH);
digitalWrite (LED4,LOW);
Serial.println ("tufreedom33");
}
else if (x=='0')
{
digitalWrite(LED1,LOW);
digitalWrite(LED2,LOW);
digitalWrite (LED3,LOW);
digitalWrite (LED4,LOW);
Serial.println ("tufreedom000");
}
}
}

You must try to explain your problem more clearly.

You must use code tags when you post your sketch.

You must post a schematic wiring diagram.

You must do these things if we are to have any chance of helping you.
