i appreciate it..but it's not fun to wait 1 month to get a part if youre not sur its the good thing you need..

yeah but i heard pwn will not work for bellimo..and that i need a clean signal "analog signal"!

Hi guys! i want to control a belimo actuator with a 0-5v pwm of arduino..but the belimo need analog voltage 0-10v! I read some thing about low pass filter. So wich component should i use to get 0-5v pwm to analog 0-10v? I read that i need a 2n2222 to get 0-10v signal and smooth it with a low pass filter. But i don't know wich component value to use for the low pass filter (resistor and capacitor).!

I'm have bad experience with transistor..one day i try to control a 12v dc motor with 5v and i use a 2n2222 transistor and the output was less than 12v..i didn't understand that too..will i get the same problem with belimo?

is there someone with an answer? Thank you very much!

Ok thanks! But what do the yield() function..i read about it on the scheduler library page but it's no very clear to me because english is not my first language and i'm not sure about this function..

that would be nice 640x480! but just one bit!

it is possible to only display black and white and get a better resolution?

Hi everybody!

What about this library: http://arduino.cc/en/Reference/Scheduler

I heard anybody talking about that library..is this multitask? does it work well? it's says that it's experimental but what's the restriction..do any function or library use with the scheduler work? do someone try it!

Thanks!

Just hook a ethernet shield to your arduino ! And communicate via wifi to you ipad??

what about using two arduino? one for rgb and other one for v sync and h sync? lol

ok thanks! So the router will take any data from the "server" like a response to the data the "client" sent if it a resquest have been sent a couple of second ago..good.

I notice that UDP does not car about client and server, you just make a UDP packet with ip and port to send the data! But do the Arduino at the other end (on a other network, i'm transmitting over internet) need port forwarding..i know that with tcp/ip the server need it..but for UDP there's no definition of server..there's no answer. there's no definition of client too..

how the data will get to the arduino at the other end if there's a router and other machine connect to on it's home network(LAN)?

ok thanks, so the easiest way is it UDP, TELNET TCP/IP????? when i look ak UDP exemple, they only tell how to send byte over a LAN network..is uselless for me. Then i read about TCP/IP, and people on the net telling it's not the easiest way.. Then you tell me Telnet..looks like the easiest way..

but if i want to  send a byte to a computer and there is several computer on the LAN network, how this computer with a server  i create will get these data and not the others? how the router will know to wich computer he have to send the data? Do the data sent arrive at each computer on the LAN network and computers who listen to a specific port get these data? or i have to setup something to exactly sent data to a speccific computer on a network???

i heard about port forwarding but some people says i'll need to set it up in my router and other say no you don't have to... i fucked up with that..

thanks a lot for your future answer

Hello guys , i would like to communicate a arduino to a pc from internet..but all i can find on the web is exemple to make http request on a web server. I want to to send byte to a PC with a C# server, and the C# server will catch up the data.. how can i do that?

ok thanks! but if i use a modem like that:
it's a ttl seria dial up modem.

Why do i need to implement a protocol or something..

up!
