[@jonmms9193]

Now I don't know if anyone has spotted this. There is a ***MISTAKE*** in the schematic at 8:11 in the video. The voltage divider is wrongly connected to the Rx pin of the 8266 and pin 11 of the Arduino MEGA. One must disconnect: 1) upper terminal of the 1k resistor from pin 4 of the 8266 and 2) cyan wire from pin 11 of the MEGA and switch them over i.e. the cyan wire goes to the 8266 pin 4 and the upper terminal of the 1k resistor goes to pin 11 of the MEGA. If you leave it as is, no voltage dividing is accomplished and the full 5V level is applied to the Rx pin of the 8266; this can stress the ic to unknown results. Having said that, CONGRATS for one more great video and project!

"Full version" of code will also work on arduino UNO or NANO (ATmega328P) if you store all string in program memory (flash) via "F( )" macro. e.g.: Serial.println(F("READY TO SEND")); ( or lcd.print(F(...)); ) Like this I reduce the used RAM to 70% (595 bytes left). Obviously I didn´t test it yet (because I don´t have an ESP Wi-Fi module). And if it will still cause stability problems you can store other variables (because 45% of program memory are still unused) (e.g.: const char SSID_ESP[] = "..."; const char SSID_KEY[] = "..."; ...) via PROGMEM macro. e.g.: PROGMEM const char SSID_ESP[] = "..."; but you will need to write a little bit of code e.g.: for(i=0; i

Hello my friends, we need to discuss basic website security please remember that allowing anyone that can see the website access to change it can result in....unexpected consequences this becomes even more important when you are controlling mechanical items through the website a basic password will stop the curious, for the determined, more drastic measures are needed do not rely on obscurity, that is useless for security that is all.

[@S0K0N0MI]

I'm a little conflicted; I can host the site locally and just go in via VPN tunnel for best security, BUT at that point ill have a server in the house already, so why not skip the arduino and use a raspberry Pi. I wonder if there is a way of making this self contained on the arduino. It can throw up a basic no frills HTML page and read data directly from its own EEPROM, so it might be possible?

Great work. Very precise and informative tutorial guides. Lots of thanks

[@sigmata0]

I hope others have mentioned this, but you've implemented no security of communication between the webserver and controller nor the between the webserver and the browser client. On the face of it I would expect anyone to be able to control whatever your website controls. This means if you set it to issue alarms or set equipment on or off, anyone on the planet could do so. You show an example of opening your door latch remotely, and in this setup anyone could do so if they found your free website. Some of this would be ameliorated if you'd implemented SSL between the controller and the website, and between the client of the website and the browser. On top of this I'd be adding an authorization page to access your control page (as a minimum). The 000website service does not provide SSL protection unless you pay for it. In fact it doesn't even supply SSH services. It's unclear if you could implement SSL yourself, using a self signed certificate or one of the free services (letsencrypt.org/ for instance). Really, I'd be more inclined to buy a small SoC device like a Raspberry Ri and setup the web server on it, which means you have complete control over how and what is implemented. This would enable you to have SSL and SSH services, and even a VPN server (like OpenVPN) if you desire. I'd then create a port forward setup on your home router to allow connections to that host from the Internet. All the communications between that host and your Arduino would be inside your local network and not over the Internet (and you could add encryption to that traffic as well if you so desired). If you wanted a specific domain address to resolve where your home public IP address is, you could use one of the Dynamic DNS services that are available for no cost. No-IP, or FreeDNS come to mind but there are a range of others who provide this service. If you use a VPN, then you connect via VPN to your host first, then either login or simply control things via the website as you've demonstrated. You could get a similar effect by using an SSH channel to connect to your host from the outside, if you didn't want to setup up VPN. Security is one of the concerns best implemented from the beginning and not just tacked on later in the process.

[@makersgeneration3739]

True true. That's a way to see. It depends also of the importance of what you are doing

[@UpcycleElectronics]

Yup. For something like a mailbox "you've got mail" notification, who cares if others see this. They could just watch the mailman for the same information. It's already public data. That's what I would do with this. In my experience, something like a privately hosted option is far more likely to fail than one hosted by a company online, but I'm no IT guy. The entire business model with these "free" web host sites is based on a long game. They are counting on a small percentage of people to build up enough presence on the site so that they use more than the free bandwidth limit. They need this bandwidth threshold to be high enough that moving to another platform is more of an expense than (over) paying for the site's services. They are trying to get people to invert the path of least resistance so that paying more is easier than not. This kind of thing takes time to develop. The only way for them to succeed is to play the long game, so exploiting the service like this is a pretty stable option IMO.

[@kal9001]

1, Pay for your own host - It's super cheap £5 a month gets you a basic web host with PHP. Or host it yourself, using a static IP or a DDNS service. A paid host is more likely to remain up all the time, and is more likely to have more secure apache settings than a typical home grown site. Either way you're still exposing the service to the internet so... 2, Security and encryption. These both work great for all sorts of things. Having your devices authenticate over an encrypted connection is all well and good, however this does add latency, security can be 'hacked' and encryption can be broken. 3, "Security" through obscurity. One should not send explicit data... send a load of random crap with your important data at known positions along the junk. don't send plain text data, just send binary and reconstruct the stuff after...etc... Also as good as this project seems I have a worry it could be bloated - I've not looked at it, and I know Kevin Darrah's work, but I suspect something is sandbagged here as I've been able to very easily get an ESP8266 to decode JSON strings with VAST amounts of text and numeric data, and pass that along to a 'duino for parsing. Having these 3 boolean limits, and an uno can't contain all the code, seems very odd.

[@omarel-azab5223]

i did that and yet the esp doesnt connect to the wifii network, any idea why?

[@kanapkazpasztetem]

I may have missed something but... 1) why do you use esp8266 + arduino mega instead of the esp alone? pin cout? - if yes then just add i2c pin expanders and it still will be a cheaper solution with the same functionality ihmo 2) while the given PHP code may work and get things done it is also not secured, it is unlikely for anyone to find such endpoint and know what to send there but some authentication would be nice 3) as above, it may work but calling "example.com/esp/update_values.php" is meh imho, URLs like "example.com/esp_apiv1//update" "example.com/esp_apiv1//read" looks much better and are self-explanatory, you can use existing frameworks like Lumen do code that or you can even add it to your WordPress website since it has also a built-in rest API (I have done similar thing) all in all good video to just get started but what was missing (or what I missed) is that it can be done better if you spent more time on it :(

[@lelandclayton5462]

I like this very much however this is how I would do it. Arduino, ESP8266 and a Omega2 or Raspberry Pi as the host. Install LAMP on the Pi or LNMP on the Omega2 since it will be the host. Sign up with a DynamicDNS and setup vLan on the router with some port forwarding and you'll have your own IoT server. Wonder if anyone has made a Arduino to Python Crosscompiler / emulator yet. This way you can just use the Pi or Omega2. Toss in a ZWave Controller and then you could really do some awesome Home Automation with it.

[@rdssdr939]

Hello Leland, I have done a project with the method you recommend. The advantage is that response time is much less. However somehow router stopped forwarding to assigned ports. To avoid router problems, one of the outputs is recycling router daily. So currently with DDNS service set on camera dvr, I get the ip address daily. But as port forwarding doesn’t work, I cannot access ardunio. Well, currently I’m 1000 km a way from router and cannot set back the port forwarding. So only way to fix this problem is replacing router with a remote control feature or to have a pc running teamviewer or logmein on it. Both options are costly. So as a result, I will have to update my ardunio that will run over a server database on internet. So if you are able to be near the router, your method is fine as you could fix issue on the place. But if you are a way and have a chance to set router settings once a year, Best to have a control over server database.

And the DB can be stored and saved on a SD card being connected through ISP? Are all the things I written right?

[@D4no00]

nice try to introduce beginners into programming world however things that should be taken in consideration are the following: - Everytime use https (you don't want your traffic to be sniffed, intercepted or changed) - A authentication process is mandatory (everybody will have access to that page otherwise) - Http is not the most friendly protocol for embedded. (In serious IOT projects nobody uses http, instead use a mqtt or other lightweight protocol proxy) - Don't use cheap hosts for such proposes (A lot of such companies have no privacy terms and the resources you are getting are very low, instead host it on your own computer or buy a raspberry pi and use it as a server) Overall this is a pretty good idea, however I would recommend you to use frameworks already done for such proposes (for example node-red) since they already have implemented things such as security that will be difficult to implement, especially for someone with no background in programming.
