Arduino Bluetooth Android - LED Controller Project

This video to show you how to connect the Bluetooth HC-06 with Arduino UNO to On and Off the LED with your Android Phone or tablet.

You can find the more detail on below link:

Android Application

Help me! Buttons are working fine. I am using a HC-05 and it is not working. I have checked all the connections properly. But when i search for bluetooth nothing is visible. Please help me

you insert txd and rxd of bluetooth module directly to arduino which gives 5v signal where as rxd and txd are rated at 3.3v. Doesnt it affect module or what would you say about it.

Hi,
I've connected me up to my bluetooth device HC-06 via smartphone. When I
try to use it disconect off and applying again so that bright flash its
on, and ready to reconnect!? Do you have suggestions on what I should
do? I have unfortunately no more Bluetooth devices to test with. Please
help me :)

can i use this to bluetooth module 4.0? does a bluetooth module 4.0 require any android version cause i only have version 2.3 and i cannot pair the bluetooth module 4.0 to my device

[akshaykapoor]

can we use bluetooth hc-05 5 pin instead of hc-06 4 pin which you used??

[basilenglish]

please could you tell me how to connect the app to the hc-06 I'm new and need to make an app with the mit adroid 2 the other ones I've tried are freezing my phone but are connecting as the light stops blinking

i used jdy-08 bluetooth module, connection error occurred. can you tell me what's wrong? is it the jdy 08's compatability?

[nganct]

hello when I unplug the port at tx and rx like you, it doesn't give an error like you, but when installing it will give an error, so what?

The tutorial is great. My problem is that the android app can connect the arduino board via bluetooth.But, pushing button(s) on the android phone doesn't light up or off the led.Pushing the real buttons on the arduino board doesn't work either.Can you help?I am using bluetooth module with BEKEN BK3231 chip.

Good work but why you did not put a resistor for led?

[mickcoomer]

Hi.

Will this work on an iPhone 6 running iOS.

Thanks.

When I run the app on my phone, I get a screen that asks for "Bluetooth paring request pin" for device "JDY-31-SPP. I've tried entering, but nothing works. Please help.

Hi! Can you connect multiple Android Phones to an Arduino?

[Dancopymus]

Wasn't it necessary to use a voltage divider on the bluetooth Rx pin?

[kuldeepjangidd]

have u created this app by your own if u then can u please explain that if you press the on button or the off button what kind of code it sends to arduino so that arduino can react to that or respond to that I have created an app which sends the char string
I set that button as a char string sender automatically when pressed when I press button and set my code that if I received that char string then that thing can be done but the drawback of this is the delay for receiving and the processing time can u suggests something

[dexterlejesta]

can it be done using NPN transistor as a switch.?

[theonechileno]

do you need the push buttons if you only want to control it with your phone?

[VIKNESHKMUCS]

what platform does the program work on?

[jameswhalow]

led without resistor
hc-06 tx rx runs at 3.3v and you suply 5v
wtf?

hi... i am planning to build a 3 scent air freshener using bluetooth module and android device how can this be posible...?
