You can try a different sd card and see if works.

I want to add a flow meter (Hall Effect) so I will know when my filter needs cleaning (also I do my water changes with the help of my canister filter, so I will also know how many litres to drain). Can anyone help me with the code? I need itoa to convert int to chars and print it on screen?

The code is designed for a 3.2" screen (320x240). If you wanted to go bigger you'd have to update the code and likely graphics.

Hi, I'm new here. Been reading this entire thread with interest.
MrMan, would you happen to have any left over spare boards laying around and if so could I get one? If not is the newest files on page 88?
Thanks in advance.

Now that is sweet! A 3D printed home for your iAqua. The link is to the maker files for it.

Problem again, whch off power filter and solenoid of co2 the mega just hang or reset, ia it EMI transient, how do you build yours, mine is in a tight cabinet with all the parts.

Could be EMI, I'm using an isolated relay module which should prevent any noise from making its way to the arduino and haven't had any issues. Keep in mind that for the isolated relay modules you find on the bay you need a separate power supply for it to be truly isolated:

Relay isolation
Thats the exact problem, relay is opto isolated but made in china and i am using 12v supply which is for the relay and regulated to 5v for mega!! I changed the power supply which i took from an old dialup router, which had 12v and 5v output and also i made RC Snubber , now problem solved. Thanks again @mr man, now i run my i-aqua, its working nicely but could not test the lighting part because i had with me just an old led lamp without dimming, i had interest in your LM3414hv led driver, that would be my next project.

Hi MrMan.
First and foremost, i really like this project and have to praise the time and effort put into it. really amazing work.
I am in the process of building one of these and i myself and an arduino beginner.
i have a small issue at the moment.
My touch screen doesnt seem to work.
I opened the serial monitor and regardless of where i touch on the screen, the x,y values are -1,-1

I have configured the display using
CTE32_R2 for the utft
mytouch as (6,5,4,3,2)

i have tried calibrating the display and i ran some example sketches which both seem to work perfectly fine (Quickdraw and touch buttons from the utouch library)

any idea what i might be doing wrong and how to fix this?

There are overlaps on pins if you use pins 2-6 which is why the TFT shield is supposed to be modified (or use my shield which does the same). The code sets those pins as PWM output for LEDs so when you also try to use them for the touch it will probably not work. Check the early pages of this thread to see how to modify your TFT shield.

It's written to run on a 320x240 screen, you can use a 2.8" tft but you'd have to go through the code and adjust image locations and touch areas.
