Can be but Solid State Relay is better than mechanical relay.

The problem with SSR is max. current (2 A).

Today i started assembly arduino mega whith screw shield and ethernet shield:

I connected the temperature sensors and tested them. I decided to use a pcb board for the wirring. So far so good:

While i 'm waiting for the lcd, i 'm searching for moonlight leds. So far for the lighting i will use:

1. 4 X https://www.aliexpress.com/item/1pcs-20 ... 0.0.OSuCeP
2. 1 X https://www.aliexpress.com/item/best-pr ... 0.0.YDBZEq
3. 20 X http://www.ebay.com/itm/231177620230?_t ... EBIDX%3AIT soldered in 5 pcb's
4. 4 X http://www.ebay.com/itm/221988226174?_t ... EBIDX%3AIT
5. 1 X http://www.ebay.com/itm/172450170103?_t ... EBIDX%3AIT

According to the above list i am looking for 3 X led so if i have to add something is at least 1 meanwell ldd-500H. Is there any suggestion(s)?

Hi!

The more cheap and easy solution is a LED strip connected to an ULN 2003.

Best regards.

The circuit is like this:

Hi,

In this post you say that V. control is a trimmer and LED-OUTPUT is a connector molex. Can you give me an image of what I will need? I quess that the jumper is a standard computer jumper.

Best regards.

Hi!

Molex 2 pins:

Buzzer:

Trimmer:

Jumper:

Hi

Today i received my lcd from emartee, but i have problems. The touch screen does not respond at all when i use the URtouch library, button test and calibration. I used the ITDB02_Touch library and responds but the coordinates are wrong. I tried several times to calibrate the screen, but no luck. Any ideas?

Best Regards.

EDIT: I replaced URtouch with Utouch and now the screen is responding. The problem is that i can't calibrate it properly. I tried many times with no luck.

[Dimitris Nikolaidis]

I managed to calibrate the screen using a newer version of URtouch and setting the orientation to landscape. Now when ferduino starts it stacks in menu 1 screen and I can't use the menus. I'm using the ITDB02 shield and the ethernet shield. Another thing I noticed, is when I use only a 12v 5A power supply, without the usb cable, the LCD screen starts blinking black and white.

[Fernando Garcia]

Hi!

Have you checked this part of your code?

Mainly:

Code: Select all

//#define USE_TFT_SHIELD

//#define USE_PIN_4_FOR_SD_CARD

//#define USE_PIN_53_FOR_SD_CARD


Best regards.

Hi,

i made the changes you suggested, and it worked like a charm!!! I had some problems using the ethernet shield, like random ASCII characters in the bottom of the screen, so i decided to remove it for now. I connected the temp sensors and all seems to go well. Do i need to waterproof them?
The next thing i' m planning to connect is the heater. It uses pin 42 right?

Hi!

It seems related with RTC not working fine. Maybe related with low voltage on 5V circuit. Which power supply (voltage / current) are you using?

Do i need to waterproof them?

Yes.

It uses pin 42 right?

Yes, as you can see here.

Best regards.

I' m using a 12V 5A power supply. Is this power enough to connect the relay board directly to arduino or i will need another one?

Do i need to waterproof them?

Yes.

Is just enough to coat them with silicone?

Hi!

You can't connect the relay board directly to Arduino. The 5V circuit on Arduino can work only with 800 mA.

You should use a step down connected to this 12V power supply as I told before.

Is just enough to coat them with silicone?

Yes.

Best regards.

Another thing, when using 12V to power the Aduino is needed a fan to cooling the regulator.

You can power the Arduino directly on 5V pin with 5V from step down so, don't needs add a fan.

[Dimitris Nikolaidis]

I' m connecting the ssr with the step down regulator adjusted to 5v, but gives no power to ssr. when i connect the ssr directly to arduino, it works fine. The power supply is 12V 1A.

[Fernando Garcia]

Join GND from power supply with Arduino GND.

Hi!

Can you post the setup and touch coordinates that are you using for your TFT from Emartee? Some peoples have problem with this TFT.

Best regards.

Hi, sorry for the late answer. The coordinates that i used for URTouch library are:

Code: Select all

#define CAL_X 0x0045CFBBUL
#define CAL_Y 0x039FC143UL
#define CAL_S 0x8018F0EFUL

I think, i changed the orientation from PORTRAIT to LANDSCAPE in calibration. The driver i used is the HX8352A.

I almost finished the led setup (i' ll post pictures soon) and i' m searching for the water top off. Now i' m using a set up providing by this thread and i' m wondering if there's a way to modify it for ferduino. I want to keep it simple. I want a pump start to fill the sub when the water level is below the floaters.

Best Regards.

[Fernando Garcia]

Hi!

Thanks for your feedback.

Which TFT shield are you using?

Regarding ATO, connect the pump to "solenoide1Pin" and float switch to "sensor3". There many topics here about it.

Best regards.

Hi,

I' m using the ITDB02 Arduino Mega shield 2.1.
