44 Gallon Pentagon Corner Tank LED Hood - DIY Build + EXTRAS

[TheDOdblG]

I don't advise hooking it up as you have it depicted in your diagram, although it may be feasible, it's not safe.  Maybe you just drew it up that way for clarity or just showing your connections, IDK, but please don't leave AC power "exposed" like that if that was your plan.  Use some type of enclosure for the wall plug, and connect the relay to the plug, not directly to your 12V AC/DC adapter.  After you make some kind of enclosure for your AC wall outlet and have the relay connected to it, plug the AC adapter into it (don't make any connections to the AC side of the adapter).  Found this pic on google (it's pretty clear on how to hook things up), it's not exactly the same as what you depicted as it
1) uses a US outlet,
2) uses AC Hot (live - the black wire) to connect to the relays then to the bronze screw on the outlet
3) uses the neutral (white wire) to connect directly to the silver screw on the outlet
4) uses a Raspberry PI to control it
but regardless, it's essentially the same as what you want to do (just swap out the Raspberry PI for your Arduino, and the US outlet for your Euro one):


Some thoughts on eliminating some of the more obvious things:

When the Jarduino "chiller" pin activates, does the LED (LED1) on your Relay board corresponding to that relay light up?  If so, good, it's sending the signal and the relay board is receiving it.  If not, then that could be the issue. 

Are you sure you have the polarity correct on the DC side of your AC/DC adapter?  That is, with your fan connected to the AC adapter, if you plug it into a working wall outlet, does the fan work?  If not, swap the +/- fan wires on the Adapter and test it out again.

Let us know how you make out.

And thanks for sharing your post on the initialization fix. Hope that info helps someone out there.

Thanks, my diagram is made that way for clarity and whoever read this to understand what i did. All my connections are made in an enclosure using insulating tape and electrical terminal block, there is no need to worry.
That pic you found is just like i did, the only diference is that i put the neutral wire to connect to the relay, not the AC hot wire.
Maybe this could be the cause, i also know that the SSR's works just with AC as a load, they will not work with DC device a a load. (Not so familiar with triacs and that other stuff in a SSR  )
Yes, when the chiller pin is activated the led on the relay pcb lights up and yes i am sure the polarity on the DC side of the power supply is correct.
I will test again, maybe tomorrow, and let you know the results.

Thank you,
Sorin

Check the fan  turns on when the PS id connected directly to a outlet. Now hook it up to your SSR circuit. You may have to invert the signal output if the module you're using is a low level trigger as per  your circuit posted.

Hi, I have a problem with the screen, I can not calibrate it well, ITDB02 TouchCalibration and modify the file ITDB02_touch.cpp but then I check and upload JARDUINO, but in the lower right I can not press the buttons, in fact almost the whole screen I feel uncalled .



Someone help me? Best regards.

Hi everyone,

After several years away from the hobby I have got the bug again and I am looking to start up again. Of course the first thing on my list is the controller. I want to make another Jarduino but the tech has moved on... what screens are people using these days?

Would be even better if someone has an up to date BOM with links to current suppliers of the parts.

Has update 3.0 been released yet?
