I’m an Electronics Engineer by graduation and proprietor of an Electronic shop ,dealing discrete components.
I worked with BPL for nearly 5 years in the field of commissioning PLCC-power line carrier communication equipments.All Electricity boards in India have their own network over power lines and they use it for communication purpose also.I am proud that I played a major role in commissioning PLCC network for National Thermal Power Corporation of India.
As I have passion for technical learning I started my own concern dealing electronic components.The touch & feel of components keeps me moving & is a catalyst to learn more… This blog is basically a backup & diary for what I’ve learned.

Hello Master
Im trying to send picture via MMS using Arduino UNOr3 and GSMModule M10 QUECTEL.
My picture take photo by JPEG camera module with arduino and saved on sd card
now i have problem . i dunno how to download picture to GSM Board and send it via MMS to mobile phone.
if u have solution please help. This is project to end this class
if it not pass. i cant end this class THanks
regard.
****Sorry my gramma is very bad ****
Can u give an email for contact ?
mail me to alselectro@gmail.com
First thing to do is to enable MMS in your SIM by contacting your service provider.Then remove the SIM & use it in the QUECTEL GSM.
Using AT commands you can send the image through GSM.Through AT commands you can set the MMSC URL . Use HTTP protocol to send the MMS message, by setting the IP address and Port of MMS proxy .
sir you have done super projects , can u send me small program to switch the relay if call is received to the gsm board
Thank you master.
I send u about problem to your email.

Dear Sir,
Thanks for such a wonderful explanations on most of the electronics topics. Your blogs and you tube channels are very simple and easily understandable.
I am a newbie to Raspberry Pi, facing lots of difficulties at the start up. While booting, I am not able to send the data to the output screen, neither by HDMI, VGI or RCA cables.
Firstly when booted with Android 2.3 OS, it was installed and was shown properly on the HDMI enabled display but later after a few minutes the display was automatically off and then was flickering but no constant output.
Later, I have tried to change the OS and use Raspbian instead and use the RCA video monitor. Here, also the green LED was blinking properly on the pi but no display.
Please help me to sort out the issue.
Thanks

Hi,
Raspbian should work fine with RCA out .No need for any settings .Try to connect the RCA out of PI to any old Television with video In (yellow jack to yellow jack of PI).
If it works then change the power source of your RCA video monitor.If you do not get any display with TV then remove the SD card & plug it to your Laptop.Open the folder & delete the file CONFIG.TXT. Plug the SD card back to PI & see whether it works.

Dear Sir,
Thanks for the reply. Finally, with HDMI to VGI converter I am able to display the output on the VGI screen, but again display is getting off again and again. By removing the HDMI converter and then inserting it again, output comes for a moment and then again no display.
Is it OS related problem? Currently, I am using Raspbian Wheezy OS with changes as you have mentioned in the config.txt file. But display is not constant and thus not able to work.
Also, I am willing to use Android 2.3 OS but no display on the VGI monitor. Moreover, there is only single line written in config.txt file of Android 2.3 Gingerbird OS.
Please provide few suggestions to solve the issue.
Thanks

Hi
Al Saravanan
Your works are commendable….
You are my inspiration…….
Actually I have a situation…..
I am having a SIM900A module and Arduino MEGA 2560.
I have seen your sim300 video in Youtube and followed the same procedure….
The serial monitor shows the same result as see in the video.
But I am not receiving a call from the GSM module.
Should I do something to the GSM module before using it with Arduino….
Or install any drivers or something…..
Pls respond to me….
I think it would convenient for me if we can talk…..
Can I get your mobile number…???

The connection between GSM & Arduino is Rx to Tx , & Tx to Rx.Ground of GSM to be made common with that of Arduino.The GSM must be powered from a separate adapter.
You can try the dial code ATD9xxx; & then the SMS code.Before that confirm that your GSM has Signal , by dialing the SIM no. from another phone.
Respected Sir, first thank you so much for give us technical knowledge. Also you are doing hard work for give all us technical knowledge and sum example so i proud to you ,I am hitesh kher belong from Gujarat city -Surendranagar, I learning Arduino UNO + ESP8266-01
also Bluetooth etc. So finally found your web and good help for my ESP8266 related equation and solution, Many blog read ESP8266 related but out of country English and method both are heavy for me ( also Indian ) but your blog is very very clear and perfect, so again Thank you so much sir, And i hope you help me i need future sum technical knowledge and help.
Hello u r really smart man and in a project i know u can make it happen so if u plz contact me i will give u all details abt it so we can go on and for ur work i will pay accordingly

Dear Sir,
For me, fundamentals matters!
I personally prefer, fundamental / concept educative online learning resources like Wikipedia, All About Circuits, Sparkfun, Robotshop to name a few.
Your online learning resource fulfills my need of a clear and comprehending electronics fundamentals learning while maintaining optimum level of quality as of above mentioned resources w.r.t. content clarity. With a natural space for improvement, step-by-step with time. We want good resources to grow better and better with time. Readers love good educators!
I’m an independent software architect, electronics hobbyist and maker.
Like my interest in music, I found in case of electronics learning, practical is essential and good mentorship (in need for me) can speed up things; though its absence will not stop you become a next inventor.
Please, keep up your good work. We love to hear from you.
Best Regards,
Himanshu Singh.
