thank you just tested your code. I doesn't get pas "stage 2". I will try some more.

I am trying all day but I can't get your code to work with the ezo stamps. This is my modified code. I first only want to use ph so i removed all the extra code. Plus don't mind all the println, I use those to test how far my code goes. const int multiplexadorS0Pin = 16; // S0 const int multiplexado...

I will see if i can make some nice pictures tomorrow. I have one thing i would like to fix but it is just for the niceness of it. I still have a littebit noise on my ph readings (see picture or click link): https://dyp.im/fIiN6fj5w9 http://static.dyp.im/fIiN6fj5w9/dbc1ca3839e7331b7dacdaae6d804c7b.jp...

Everything is still working great. I added a ph stamp. I can now make my aquarium cooler fan run when it get's to hot. And i added a 433 transmit module to the ferduino so I can switch on my wireless power sockets in my home (klik aan klik uit). I can now switch on remote my hd-camera to have a nice...

Yes you are right. But maybe it is good to have a topic solely for this. It is imposible for new people to find stuff if they have to go through all the build topics. On other forums they encourage you to make a new topic with good title, but if you don't want that good also. I found out: -I tested ...

Hi anyone any thoughts on how to fix this? I have the ph sensor and atlas stamp working perfetly. But as soon as i turn on my maxpect gyre flow pump. The readings go to 14 and no more good measurements. Any ideas how to fix this?

I now see my post makes no sence. I somehow mixed up a different post with this one. So pls forget my above post or delete it.

Dale I don't think you need a multiplexer. I guess it is the same with other systems. First do the ph measurement in a glass of water. If that is stable then your sensor is working right. If you do the same in your sump and you get eratic readings. Then you issue is that one of your electronic devic...

I know that's what i meant. I fixed it by running the serial,38400 and now all is wel. I also added this to my install tips and tricks.

If have the new ezo stamp, with ezo on the bottom left. You first have to change the baudrate from 9600 tot 38400. You do this by running the test code for the stamps and open the port of the stamp you want to use. Then enable carier return in the serial monitor. Then enter SERIAL,38400 , this shoul...

Tnx it took me a while before i figured out you have to run these commands with the stamp testcode. But it worked it is running at 38400 now

Ok how do i do that? I know how to open serial monitor in arduino but how do I enable cariage return?

For now changing the serial3 baudrate to 9600 seems to do the trick. I will now research on how to change the buadrate of the stamp form 9600 to 38400.

Yes I also imported the changed stamp code you posted.

How do I solve it then? Any tips?

Fernando,

In the webbased version serial3 get's intialised with 38400 in setup. So i should change that to 9600 no?

I will try tonight. I did find out they changed the baudrate from 38400 to 9600 with the stamps. So I will change serial3 to 9600.

That is what I did. But gives me above result.

I am now working on the PH stamp. I have the latest one sayin ezo on the bottom left. Does this stamp need some changes in the code? I now takes about a minute for the board to completely boot. You get a lot of flashing images during boot. Then it boots up en shows ph. But after say 30sec it will re...

I just bought a atlas ph stamp but nowhere on the print it shows what version it is. It looks like this:

Can anyone tell me what version that is so I know what code to use?
