Hello! I’m Murli Shenoy, Electrical Engineer by trade as well as religion. I love building things, mostly electronics and embedded systems.
I also love photography and biking.
Here’s my attempt to blog the interesting things I’m working on. I have promised my self that I will post one blog post a week and have moved over to a more powerful, custom hosted blog over from a free one.
If you have any cool electronics ideas and would need help building, please feel free to get in touch with me. Also if you would like to get in touch with me, drop a line below!
Thanks! 🙂

hi we are looking for constant current resistance for some of our led applications. if you know some one who makes it or supplies it pls do revert.
thanks

Hello Mr. Shenoy, my name is Gaby and I am going to school for my A.A. in computer and electronics. My classmates and I are building a microcontroller controlled RGB LED moodlight using a bluetooth class 2 module. We were trying to use the AUBTM-20 but were not able to find it, so we used the HC-05. We are having a hard time putting everything together as well as translating the code to assembly language for the microcontroller to be able to read. If this is something you wouldn’t mind lending your expertise for our project, I would really appreciate it! Thank you =)
Hello Gaby!
you can use the HC-05 instead of the aubtm-20 since they are very similiar.
I have a post here and i have included the source for the code as well here.
I would surely like to help!
Which microcontroller are you using??? It’s likely that the microcontroller has a Compiler for some high level programming language (like C or basic). That would do the translating to the assmebly code for you !!
hi murlidhar
my name is gaurav im trying to make a bluetooth speaker system using a aubtm23 bluetooth module. the idea is to take the sound output from the module and connect it to an amp. i have a lot of questions as i have never worked with bluetooth a lot can you please help me my email is gauravsharma123 at hotmail dot com
can i use this module for audio streaming ?
will i have to program it? or is it going to be plug and play (as in solder the pins)
please reply
thanks in advance
Hi Gaurav,
Yes You can use the module to stream audio. But you will need to use a PCB audio Codec chip followed by an amplifier stage to drive larger speakers.
If you are looking for a quick solution you can even try salvaging a circuit from a bluetooth stereo headset and attach an amplifier to it.the headsets are available cheaply for less than the price of a AUBTM-20!!
Hey Murlidhar,
My name is Scott and I have a few creative ideas that use bluetooth technology and I was curious if you might be able to help me with some of these concepts I have for bluetooth driven products that don’t rely solely upon visual interface controls (ie phones and computers) for augmentation of their applications. I’m incredibly unknowledgeable on how all of these things work, but I ran across your RGB Light Stip project and it partially coincied with a project I have had in mind for a very long time but have not been able to make headway on due to lack of technical expertise. If you have some free time on your hands and could help point me in the right direction on how to make some of my ideas work I would be incredibly thankful!
There is virtually an infinite amount of technical resource out there. Start with your project. You can use the many open-source projects on the internet , including mine as a starting point and then mod/hack them to suit your needs. And if you get stuck somewhere do let me know ,I’ll be more than happy to help you out!!!
Best of luck!
Sir can i transfer data through wifi to 8051 microcontroller ?
