CODE IS HERE: int ledPin = 8; int state = 0; int flag = 0; void setup() { // put your setup code here, to run once: pinMode(ledPin, OUTPUT); digitalWrite(ledPin, LOW); Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: if (Serial.available() > 0) { state = Serial.read(); flag = 0; } if (state == 0) { // Compare with integer 0 digitalWrite(ledPin, LOW); if (flag == 0) { Serial.println("LED: off"); flag = 1; } } else if (state == 1) { // Compare with integer 1 digitalWrite(ledPin, HIGH); if (flag == 0) { Serial.println("LED: on"); flag = 1; } } }

Nice video presentation, some points to comment: The HC-05 module used in this tutorial clearly states "3.3V LEVEL" at the RX input pin 0:33 . The use of a voltage divider (1k/2K) is recommended. Also a resistor (470-1K) in serie with the LED is recomended. (The Arduino ATMEGA328 is being stressed out of specifications).

Thanks a lot!!! I faced some troubles with my HC-10, but you tutorial has helped me :)) Great video!)) Code I've used is below: int LED = 12; int state = 0; int flag = 0; void setup() { Serial.begin(9600); pinMode(LED, OUTPUT); digitalWrite(LED, LOW); } void loop() { if(Serial.available()>0) { state = Serial.read(); flag = 0; } if (state =='0') { digitalWrite(LED, LOW); if (flag == 0) { Serial.write("LED: off"); flag = 1; } } else if (state =='1') { digitalWrite(LED, HIGH); if(flag == 0) { Serial.print("LED: on"); flag = 1; } } }

for TX and Rx there is a 3.3V level, so according to me we should be using resistors or potential dividers as the uno board output is 5V. am i right???

Hi I have followed all the directions from your video and have established connection with the bluetooth and my phone. However, the LED will not respond when I send the signals from the Smartphone. The only difference between your case and mine is that I'm using a Arduino Leonardo instead of the Uno.

CAPS matter. Your video has a code error void loop() { if(Serial.available()>0){ state = Serial.read(); flag=0; SERIAL needs to start with CAPS "Serial", you have 'serial'. state = Serial.read();

Bluestacks will bombard you with ads and isn't for developing. Likely wont work for bluetooth. Use Andyroid with a computer that has bluetooth support.

Thanks alot for your important information Tx comes with Rx and Rx comes with Tx. I messed up with connecting Rx to Rx and Tx to Tx like I used to connect an Arduino Pro Mini via Arduino Uno to PC.

I don’t understand the “flag” statement, what is it used for?

I don't understand it either, and I watched the video a few times now. If anyone can give us an answer on that, would be very nice.
