Hi,nice instructable.How could I access different arduinos via my ethernet? EG five arduinos, accessible from the web via port forwarded IP through my router - or would I have to use one arduino to route appropriate traffic to relevant arduinos?Many thanksD6
If you want to use an adress from "the outside of your network" you need to portforward your router. So you may ask yourself what is portforwarding? For example http servers uses port 80. In your house you have let's say 5 PCs, each with a different internal IP adress. The router needs to know where to transfer the info from port 80 because when you use the ip provided by the internet provider you contact the router not the arduino/pc. If you want to acces your arduino, you have to say the router to which computer he has to redirect that port. Something like: Internet -> router -> tell the router to send the information to arduino (portforward)->arduino. I never used a ethernet shield on my arduino and never dealt with ethernet on arduino, but I think that is your problem.
Is it not necessary to setup the ir mode in void setup() ???
Hello everyone,I am a beginner with Arduino, actually, I want to use an ethernet shield with Arduino. but there is one question my mind. Can the ethernet shield attached with Arduino be used as OUTPUT to collect the data from sensors or always it only works as an INPUT for the internet connection?Thank you in advance for your precious time.
OK, I will tell you as soon as I receive my arduino!
very good, like I said this works perfectly for me. let me know your outcome! good luck! - MikeT14
vey good! let me know your outcome. like I said this works perfectly for me. good luck! - MikeT14
Dear Mike,Thank you very much for your prompt answer!This is very close to what I need! I have to change high by low and low by high because relay from my board turn ON with a 5 volts signal!I will let you know if it works well, but not tomorrow, I am waiting for my Arduino board....I will normally receive it soon....Thank you again to share your work, it will help me for sure!Regards - Philippe31470
Hi MikeT14!I am interested by your code. Could you share it with us?Thank you! - Philippe31470
This is what I use to this day and it works flawlessly for control of my home with my phone. - MikeT14
what are the changes to be done in the given code when we use 2 sensors instead of one?
does it move in all 4 directions including backwards
hey why you'v given datatype as char letter and value as int. and what does letter signify.
hey can we move in all 4 directions i.e including backwards
Got it working on Arduino Nano with UIPEthernet library! Thanks!https://twitter.com/Kaji_fi/status/688701859125678...https://github.com/ntruchsess/arduino_uip
Hi,I am having Arduino Uno board with me. Which ethernet shield is compatible with Arduino Uno?Thanks.
Hey man! The IR sensor that i have shows either 0 or 713. Is my sensor digital? How do i get analog outputs?Thanks in advance!
