ye error aa rha hai.kaise sahi hoga bhai ye.
Remove Bluetooth and try again
same error is occuring
Bro check below the code I’ve inserted a link
this code is running bro
thanks 🙂
how to remove a bluetooth? same error
oooooooo the code was working 🙂
What is the error ?
Ohhh sorry didn’t read your messege . Oooos
how

Sir… how to protect it by password so that no unauthorised person can control it…
Wow ! Need to check , great question buddy
You need to change it using at commands
BRO EK NAYA PROJECT KE BARE ME VIDEO TAYAR KARO
SUB :- PLAY MUSIC VIA ONLINE USING AURDUINO WITH VOICE CONTROLL
I’ll try
bro ye error kase remove kiya
Bro the programme is saying can’t upload to board plzzzzzzz help me plzzzzzzz and one more thing is that I am using 8 channel relay board of 8 channel but it is having pins like in1, in2 and so on I the relay board correct
Love ur videos
What is the error?
Hey shree is ur problem resolved becoz I am facing the same problem “can’t be upload to the bord” plzz can you help me out plzz its urgent

Hello Harsh,
I am just trying to compile the above code but it throws error, I tried to resolve syntax errors like ” & ‘ and tried to compile it but it throws below error;

Could you please look into this and help me out.

The issue has been resolved now and IDE able to compile the program, now I facing issue while upload it throws error;
avrdude: ser_open(): can’t open device “\\.\COM1”: The system cannot find the file specified.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
Please help!

Resolved, you need to set Port in Tools–>Port.
Regards,
Rahul
Port problem… hehe glad to hear that you solved it yourself
Hi,
Good that you noticed my comment! 🙂
One more question.
Everything is perfectly setup for me but still unable to switch on and switch off light, could you please tell me what would the cause? And specifically why you used Device 7 button in Arduino Bluetooth Controller, any reason?
Regards,
Rahul
pls reply..
bro uploading error aa raha hai

Port correct hai ? Tools par jKe check kato
apka yeh error solve hogaya???
Yes sir
give me a andriod application
Bhai agar meko isme kisi ek port pe dc motor lgana ho..and to programme that port to operate dc motor in both direction..to us port pe programming kaise hogi..is it possible to programme that particular port as our requirement(in the same programme)?
Problem solved.?
Glad to hear that
That’s interesting… need to check idk this rn will let you know
Nhi ho payea sirf ek side run kregi bcz ek relay pe ek switch hai..we need two differ swlitches..instead of program just apply simpl logic changing the polarity of dc motor changes the direction of rotation..?two battries use hogi or ek motor ko dono se connection dena..bas polarity change krna
What if i have to on/off a light both in automatic (using bluetooth) and manual(using switch) switching?
You can turn it off from switch not sure about turning it on..
Sir jab m arduino ko program krny k bad suply k sath cnect krta hun..
To arduino terminals always onn.. (1)
So relys b onn e rehti hen… blutooth is also cnect to android… butt never work.. lamps always onn… so help me plzz pllzz…
Contact me on my Facebook Id I’ll help
Jab relay on ho rha tik tik sound aa rhi hai ya nhi?if not then check ur jumper conection on the end of module u can see 3 pins on board..i have been through same problm
Jab arduino on krta hun to sath hi relays b on ho jati hen.. phr arduino ko bnd krny k bad hi band hoti hen.. otherwise chlti rehti hen.
Jab arduino on krta hun to sath hi relays b on ho jati hen or relys k on hony ki sound b ati h.. phr arduino ko bnd krny k bad hi relays band hoti hen.. otherwise chlti rehti hen.
i cant able to upload programme showing some error
What is the error ?
If we turn off the bluetooth from our phone will the bulb still glow ….
and apart from the work are you a web desighner too i like your work i am also an IT student..
It will remain in the last position…. ohh you tooo it ? That’s nice !
Bluetooth module asking pairing key
1234 or 0000
Now working
Glad to hear that
Not working
Error?
hi harsh,
appreciate your work a lot….i’ll definitely try making it…i had a doubt that whether we could control it using wifi or not?
thanks for your support.
We can do it via wifi as well but it’ll need different hardwares
application use in this project please?
Can use it at our homes
