Hello how is possible to connect wirelessly the pins of MAX7219 (CLK, CS, DIN) to Arduino pins? So that there's no more physical wires that connects between MAX7219 and Arduino. Thank you.
Sir what's the resistance reading of your working hc-05 if you make the state pin common and check all pins, do they have all the same resistance including vcc pin? because mine is not working and there is zero resistance between state pin and vcc?
Hi, I've followed your and other tutorials. But in every case, hc-05 does not send data to the serial monitor. Even if everything is connected correctly, the code is correc.I removed the wire before the upload, the baud code on the serial monitor is the same as the serial begin and hc05. I even tried different applications, but none of them work. With some miracles i setted the module to slave.But didn't work either. Did you know what can cause this problem?
Similar to tutorial, configure more buttons in the Android app by giving any of the characters. Add more if-else statements in the code as shown and compare same characters configured in the app. Similar one : ruclips.net/video/5JLXpp7_l-E/видео.html
@techathome hi thanks for your reply..I have configured the app for only 2 values A and B I can see these values in app terminal..but seems they don't reach serial buffer of arduino..only when I provide values in serial monitor manually it works
@@techathome the values coming from app are not visible on arduino serial monitor...but these are visible only on andriod app terminal...however when i type value on serial com4 on arduino terminal i see the values come on app terminal as well..
in my case i have to connect the HC-05 to my Arduino mega 2560 but the problem that i can only either receive or transmit data from the Bluetooth serial controller even tho i did the wiring and the code for both RX and TX . can anyone please help me find the problem ?
Great tutorial it really helped me solving my issue! I also had a question, how to make led blink when turned ON and stop blinking when turned OFF? In my code when I keep pressing button on phone the led starts blinking and when releasing it stops It would be great help if this is fixed since I am working in my project and this the only video that helped
I got everything basic stuff I wanted from this video but now I want led to start blinking/flashing when pressed ON and stop blinking/flashing when pressed OFF from mobile app
@@dhruvgoswami6819 set your arduino code to blink the led when your button is high and stop the blink when the button is low thats it to blink a LED use arduino basic blink sketch

The world's best teacher thanks sir
Welcome
Thankyou it is because of you ive learned... no other video on Internet explains like this thankyou so much
Thank you ❤️ for the feedback!
repe
Why we don't connect state and en pin and is it will only work or the bluttoooth module will get power when code is uploded
Exceptionally good video on this topic. Great content. 🔥💯
Thank you ❤️
THANK YOU, GUYS FOR GIVING FEEDBACK
WE REFER ANY VEDIO THROUGH THIS ONLY .

Same problem with me
Same problem did you find solution?
Try going to Android phone and clicking Bluetooth and connect the module
You fried your chip use a voltage divider with 1k ohm and 2 ohm resistor

your video is best.. I am absolute beginners so please tell me i glow more than one led lights at different buttons

It works perfectly
Even a 13 year old can do it.(bcz i am 13)
Thank you!
Do we require resistor for the led ??
Pin 13 has inbuilt resistor,
It's better to add if using other digital pins.
Plz provide the link for the bluetooth serial controller app ,I couldn't find it in playstore

I have given APK download link from description. You can use that.
hi the led switches on and off when I send commands via serial monitor but not via android mobile Bluetooth app .. why so ?
Have you configured the app correctly?
See the values coming on the serial monitor if it is receiving correctly from the Android app.

The drive link provided in the description is working for me, tried in different systems.

Was this 65/66 feed in the device or is it in-built ??
Those are standard ASCII values for alphabets which, compiler will understand

hello how to turn on and turn off the led only one command .same for on led and same for off led
Use this code:
//RUclips | Tech at Home
int led = 13;
int data;
int x=0;
void setup()
{
Serial.begin(9600);
pinMode(13, OUTPUT);
}
void loop()
{
while(Serial.available() > 0)
{
data = Serial.read();
Serial.println(data);
if((data == 'A') && (x == 0))
{
digitalWrite(13, HIGH);
x = 1;
}
if((data == 'A') && (x == 1))
{
digitalWrite(13, LOW);
x = 0;
}
}
}

my hc05 led is on but does not blink and is not discoverable what should I do?
Can u check Rx and TX pin connections
@@techathome yea the connections are fine the led is steady and on but not blinking
Why SoftwareSerial.h library not included
Because you're using the Rx & Tx Arduino pins, so they're made for transmitting and receiving info from external devices such as this bt module
Sir does this works with COM 3 port?
Com port number changes from board to board.
You can directly select the port which shows in your Arduino tools .
Can you share app link..
