About Me
Hi
I am Radhesh. I am a Telecom (Electronics) engineer and I have spent more than 10 years now writing software for embedded systems.
I feel Arduino has revolutionized the embedded field. Just like how Microsoft brought computers to comman man, Arduino has done it for embedded systems. But if you want to create hard core embedded product, you need to come out of comfort provided by arduino libraries. Nevertheless its a good starting point.
Raspberry Pi is another example of similar product. Thanks to open source movement.

would you like to contribute to this?

@Vishesh,
Nice work. I would be glad to contribute.
hey…. its great. you have touched variety of matters in your blog. its maintained so neatly
@ Akshay,
Thank you π
Hello Radhesh. Its really a useful blog. No wonder, in 4months, the number of visits crossed 3000. Just continue blogging and your site will be much more useful.
A suggestion is to have a page/announcement for the upcoming reviews. That will compel some visitors to visit again. For instance, you can put up an announcement, when you start reading a book or when a new movie releases. You may also wish to have a page for readers wherein they can post about some book/movie/gadget that they read/see/use before you do.
Best Wishes.
@iisc,
Thanks for dropping by. Of late i had been posting more reviews. But i dont want my blog confined to that. Thanks a lot for ur suggestions.
Hi Radhesh,
I really impressed by your blogs on control systems comparing with commercial massal and explaining PID controllers.
it also shows sincere love towards our kannada culture. keep it up, best of luck.

@Ashok,
π Thanks for dropping by.
Thanks for stopping by my blog. π
hey , interesting blog…. way to go… π
@ sunnysideofliving,
Welcome !
Thanks for reading my blog!
hey dude have you stopped blogging. your blogs used to be interesting . . .
@Madhan,
I am back dude. And what do u mean by ‘used to be’. π
Hi Radlesh,
Can u explain the basic operation of PID Controller for HYDRO turbine-Francis type?

Hi Radhesh,
Why stopped blogging after 2009??
My name is Marina, i work for Jaico Publishing house, i would love to send books to you for reviews. please contact me for any information at mediarelations@jaicobooks.com
right now iβm trying to control a Oven with a temperature controller I created. How I get the transfer function and how I simulated it with Matlab? Please let me know if you can help me, its for a college project . Can you contribute, Thanks
Please contact me ing.eze@hotmail.com
How exactly are you controlling temperature? I need more details.
Hi!, im controlling a furnace with a Arduino uno and various other components. I creates the code and it works good, but it need to perfectionate the PID tuning. I did the PID tuning manually.
This is part of the code:
error=ref-temperaturaLeida;
errorDer=error-errorAnt;
errorSuma += (ki*error);
double U=kp*error+(errorSuma)+kd*errorDer;
//u(t) = {Kp*e} + {Ki 0-Οβ«edΟ} + {Kd*de/dt}
If you want to see the code or pictures of my results just let me know. If you need more details, just ask. I can send everything to your email
For integral part you should multiply with time raster too. How frequently your code is getting executed? I would suggest you to remove I and D part and try to control only using P part. Then add I part if needed. For this you need the time scheduling info.
Can I send you everything to your email? The sampling time is 1mS
Mail to radheshpai@gmail.com
I just send the info
