Hello Friends,
Welcome to my web portal. After my long play with the amazing little chips called microcontrollers, I decided to help all those who are also interested. I knew that the information on the net was very scattered and a beginner soon find himself/herself lost. So I came up with this !!! I decided to keep things simple,organized and in one place. I have tried to go in such a manner that a complete beginner to the subject may keep up. If you are having any types of problems or just want to help others please join our forum . Also check out our shop.
If you find this site useful please drop a comment or e-mail me, I would be glad to hear from you.

Please move discussion to forum

As this topic is irrelevant here.
Also the answer lies in a quick search
Hey Avinash
I am calling you today….but i couldnt found no phone is answered. I want to buy low cost avr develpoment board. Is stock present now? what are your contact timmings
@praneeth varma
How many ?
Please don’t call me on SAT or SUN!
Better if you call me after 10:00 AM Morning till 1:30 PM
Much faster response if you use email! I am online most of the time.
Hi Avinash,
thank you for the… “AVR Graphic LCD and Accelerometer” Demo.
Unfortunately the code from the website is unavailable.
where can I get it.
Best regards D.Schnabel
AVR Graphic LCD and Accelerometer Demo
@Dietrich
The codes (both hex and source) are available for download! Please go try them.
Hi avinash,
Thanks for the fast answer.
Your Graphic LCD library is great. But with a flexible pinout configuration ( in a headerfile ? ) it would be super great.
Best regards Dietrich
@Dietrich
I have hardcoded the PIN mapping because. I wanted the end applications to be portable. So that applications created by all peoples are compatible with hardware of other people. So they can be shared and run with minimal efforts. Also the library is well ahead of other available and I have many plans to make it even more powerful. But to keep it free of charge I have made is closed source.
Hallo Avinash,
too bad, with your configuration C0 C1 are not available for using the Hardware I2C.
Best regards Dietrich
Avinash Ji, hello!
First of all I thankyou for early replying and uploading the status of my ordered products. I have assembled remote controlled fan regulator, and want to share a problem with the circuit which i have faced. The problem was that when running the fan/bulb(60W) on dim the R13 resistance starts getting heated and within 5 to 10 minutes the capacitor C3 gets shorted and the fan/bulb starts running/glowing at full. I have replaced the resistance R13 with 39 ohm/ 5W and capacitor C3 with .47/ 400V and tested the circuit for an hour and every thing was OK.
Thanks and with regards,

@Mr. GURJEET SANDHU,
Thanks for sharing the info. It will lots of other people.
Hi,Avinash……dude r u ok?????No recent update about AVR?????.No more Tutorial?????R u ill or something????

hi Avinash,
Good work from your side and I appreciate ur eforts and expecting more from u.Also let me know how u receive payment if I order one.Accept cards or ??let me know
Thanks& Regards
hi Avinash,
i am using your LCD interfacing in your xAPI Lib, but i made a mistake in my PCB,i used the wrong data port on it like fallow:
Port PB3-PB7 are connected to D4-D7
but in your lib the port is:
Port PB0-PB0 are connected to D4-D7
how could i change the code to fit my board?
Thanks!
Hey avinash… nice work.
It would be better if you could sort these post according to time of post: most recent first. So the latest ones come to the top..

hi…….
I have purchased extreme electrnics USB burner for 8051 and AVR. they were working well. first of all, I like to appreciate ur eforts. good work Avinash.
but the software for 8051 burner is lost and the CD send by you is not recognised by my DVD player.i think CD is being corrupted.
so can I know from where i can download the same again.
Thanx
Hi,
I am interested in developing a moisture sensor for use in soil beds in a greenhouse. Sensors would send wireless data to remote control panel.
Anyone knowing of availability of off-the-shelf IC’s or interested in development please respond with information.
Thank you

Hi Avinash,
I saw a website which says USBASP programmer by Fischl can be used to burn AT89S series of controllers. If this is so, can you please try it out and help all the customers who bought the USB programmer from you in updating the frimware.
The link is given below.

hi avinash,
no recent post, no more tutorial ?????? what happen bro???? i hope u r fine.and also pray to my god to bless u,if u r ill.
hope that u will start writting again.

hi avinash,
ur products are of really good quality and ur service is also very fast.keep up the good work.
well i am curious to know,is it possible to interface a camera
to any atmega or pic microcontroller’s.if yes than what all things r essential for such a project?i know it sounds a bit amature type of question,but i am just too curious to know about it.
@rajam
Thanks!
“possible to interface” is too broad to be answered. The answer can both yes and NO.
I have usb pic programmer v 1.0 and I have download extreme burner2.0 of pic from your website when I load a hex file and click writeall option then a problem occure show as a “programmer not responding” in progress window can u help me
what is the problem?
@mubin
Post your problem in the forum
http://forum.extremeelectronics.co.in/
With your Order ID and Date of Purchase.
How about doing a tutorial on I2C interfacing between AVR mcu’s.
Really like your website! Keep up the good work………..
@Robert Young
Coming soon …
Hi sir,
i want to buy a GSM SIM300 module can u tell me details about this,Thanks.
Avinash,
Your tutorials are superb! Best thing I’ve seen for AVR; and all in one place! Good job!
I like Robert Young’s suggestion on doing a tutorial on I2C (maybe include SPI?).
I’m just starting on MCUs with an AVR32 on at Atmel AT32UC3A3256 development board, together with an AVR Dragon debug board and a 9DoF sensor board. My development system runs Ubuntu 10.10. First project is motor control of four small DC motors for a quad-copter. Since the motors will only run in one direction, does it make sense that I can control them all with just one L293D? I’m thinking of using the Enable1/2 to control the ground legs to the motors and Input1/4 to control the Vss legs. Is this reasonable?
dear mr. Avinash, i am professhnal electronics tv,dvd eng.But my knowledge about micro tecnology is too less. i have want to upgrade with advance tecnology .how can i learn&study microcontroler,microprosser,eprom,ram,dram and much more. ihave too crazy about it. Sir please-please help me iwill thankful to u.

Hi there
I am new to the world of micro-controllers. I am working on a project where i have to sample voltage of a circuit , using PIC micro-controller. Got any links to relevant simple tutorial?
Thanks
Neha
Hello,
I have a suggestion in the Xboard2.I think that you may integrate the heat sink for the voltage regulator. Otherwise it will burn after some time.

hey avinash!!
i am using a ATtiny 2313 microcontroller and using a ultrasonicr range finder SRF04 for obstacle detection and distance measurement….can u please help with interfacing the sensor with microcontroller and using it to determine obstacle distance…
@ishaan kakar
What will I get in return ???
And don’t clutter the comment space.
Why will any one write code for some unknown guy???
Why don’t you ask the guy from where you have purchased it ???
Its all here, but you will have to put in some work…

Pragyan 2012
International-Technomanagement festival
http://www.pragyan.org
Engineering is all about imagination and ingenuity. Rather than just theories and their application, it revolves around simpler domains such as indigenous thinking, common sense and elementary logic, all of which arise from the Supreme Intelligence, the “Pragyan ” in us. Technology, as we know it today, is the manifestation of millenia of Pragyanic thought and action, which has unflinchingly served and enthralled mankind since the invention of the Wheel.
Pragyan, the annual Techno-Management festival of NIT, Trichy is a humble attempt to promote and foster this co-existential relationship between Man and Technology. The insignia, insinuating Man’s eternally progressive leap over the Wheel of Technology, is symbolic of Pragyan?s endeavour to inculcate the spirit of engineering, innovation and forward thinking among the youth. For over half a decade, Pragyan has worked tirelessly towards this goal, by churning out seven memorable editions, each of which has enlightened, emboldened and inspired an entire generation of engineers.
To the freshers, welcome! To the seasoned, welcome back, to this journey of exploration, revelation and awe. Come February 2012, NIT, Trichy will be the epicenter of a scintillating Celebration of Technology, and you are invited to the party!
