First Project with SainSmart Equip

[Curare Widow]

Hello Arduino Growing Friends

First I must say that I had worried me SainSmart equipment only because of wrong recommendations.
Today, I would recommend every newcomer to the Arduino world, even the original hardware. The original Arduino hardware is a little more expensive, but a beginner can avoid a lot of trouble.
Example: http://www.mikrocontroller.net/topic/273121

But I will still try to show how far I have come with the SainSmart scrap. In the beginning, I still thought everything is OK!
Of course I have read myself once smart.


and RTC for Time, DHT11 for Temp/RLF Module

No idea of C + + I then remained on the side of Henning Clarsen.
http://www.henningkarlsen.com/electronics/index.php
Caution! There is only support for Arduino original equipment.

The usual pages about Arduino should indeed be familiar to anyone
http://arduino.cc

Next, I informed myself about graphics and raw files.
In addition I have been experimenting around with Gimp.
http://www.gimp.org
At first it was a lot of stress at once. I had no idea of C + + and the graphics also no secret levels. After many trials and experiments, I then got it like that with the graphics could work on the touch screen.
So I tried through the use of raw graphics to make the source code clean and simple. As a beginner, it may be awkward but as a SainSmart mega 2560 r3 also has a limited memory.

So in the end I made ​​a few icons and graphics with Gimp together. For the icons, I simply used the beautiful iconset from here.
http://gnome-look.org/content/show.php/Sphere?content=158778

Everyone can even imagine that I would have never worried favourite moment during this time the Arduino or SainSamrt equipment. I only knew WinCC and S7 from Siemens, so that I could get through the industry standards and fewer problems. Unfortunately the equipment from Siemens is also considerably more expensive. Furthermore, is not necessary and too expensive for the private mini Grower such industry standard. I wanted to build, not just painting by numbers indeed himself. I got it now ...

So we look at what I have built to date. All Images are in My Profile Album



Unfortunately, I still have problems with the SD card or is it a problem lies in the source code. I need to investigate more.

Read from the SD card works well, but strange things happen when you save everything on SD-Card.
At the end the file system of the SD card is still readable. There is something with the "tinyFat" Library not, or my understanding of C + + is not enough.
Alternatively, I could still use 512 byte memory of the chip.
Maybe someone has the same equipment and also problems when saving the data on the SD card. I am convinced that I have problems because of the cheap chips. My Shield is also v1.0 from SainSmart but i have no Problems to Connect the Card .... ^^

Soon I'm going to build an enclosure. A test run will be bringing a few more results soon.

Caution!
And please, no questions about the source code. I'll summarize at the end of this project, all in a zip. (mayby at along the Christmas time 2014)
But now I already know that no one could use the zip. Because Arduino is something even build at the end. Perhaps this project is someone some inspiration or help to make something new. In the end, everyone has to be your own source code to build your own project so that the whole can be Understood.

Update coming soon ...

Hello Arduino Grower
Today I want to quickly give you an overview.

Equipment: http://myworld.ebay.de/profit_vanity
1x Sain Smart Arduino Mega 2560 r3
1x 3-2-TFT-Touch-LCD-SD-Reader
1x TFT-Shield

1x RTC
2x DHT11

Sensors for ph & ec value and the level sensor for the tank or mixing plant for the fertilizer to make other people thought. My projects are simply too small for so much technology.

So first I got to thinking about the images for the touch screen. After several attempts I found a way to bake me a few images. The beautiful tool Gimp has helped me.
In the picture you can see how I have the images saved in the end. Later, I edited all the images on the website of Henning Karlsen with the Converter. (.jpg to .raw)



Next, I arranged the necessary libraries from Henning Clarsen Website (tinyFAT, UTFT, UTFT_Buttons, UTFT_Geometry, UTFT_tinyFAT, UTouch, DS1307 & relay8 for later use).
Now I could try with the Arduino firstonce the example sketches. As I understand now how do I use the touch screen I started to construct suitable functions to the .raw images.

.... It will soon build a suitable enclosure time.

Today I have changed something in the images because there has been an update of the icons.
Many THANKS to the author potzblitz7.



On the screen shot looks like everyone I complicated the images to save.
Save as 16 bit bmp -> Save for Web in jpg with Skip Exif, then turning to the website of Henning Claarsen to change the jpg in a raw.
There is certainly also a professional solutions but I am not a graphic designer.

For the optical gimmick with the graph I have now a few lines painted on the screen, RLF is *2 at y-Skala. I have no time to take care of a matching box ...
I still need to build a grow box equipment also still missing. I hope at Christmas time I have everything ready.

 

[Curare Widow]

In the beginning I worked a plexiglass disc. I have an old electric fuse disassembled to get to the spring mechanism.

Now I can simply remove the plexiglass disc and install as an electrical fuse.

My Arduino gear I then set up easy.


My next step is the installation of my touch screen display in the lid of my box.


I will continue to report whether my Arduino sketch running well.
I'm curious how it will work.

Hello all,

I am also fooling around with Arduino and 1-wire devices for grow room implementation.

I am beginning to get a handle on C++ and the C derivative the Arduino uses. I also have the same arduino clone as you and have not had any issue with not functioning as expected.

That said, my coding skilz are very antiquated (Fortran/Basic/Qbasic/Assembly) and C++ seems almost like a foreign language.

All of the above programming languages aer process oriented while C++ is a object oriented.

Ok, this had me confused for the longest time. C++, to me, is just more complicated and the syntax is confounding to me. Object oriented programming is hard for me to cross over. But I think I am seeing light at the end of the tunnel. I have been working on the project now for about 6 weeks on and off and have written(hacked) small code snippitsd to read the microlan network for available 1-wire devices and store the device addresses in an array to be sent to the serial monitor for verification.

I have coded(hacked) Visual Basic snippits to send to arduino a read microloan command and read any returned data.

At this time, I am just working on basic communication between VB and arduino. Dallas/maxim chips are limited now to basically temp sensors, battery monitors (which have an a/d pin) and 8 channel/2 channel digital addressable switching. My vision is a "growtronix" type of system that I intend to open source. This of course has already been done....check out aquarium controllers...very similar in operation.

I am semi retired so the project has up and down times. Going work on coding tonight.

Also, I am interested in backyard grow security as well since a buddy was nearly ripped of his years worth of meds. I have been thinking about using PIR sensors to trigger a car alarm circuit and turn on the lights. Could use existing exterior sensors to turn on and off things like lights or a loud radio..

Look forward to your project.

In time past I have made ​​some order in the wiring.
The additional RTC I've shared. I had not dared to break me apart the board. It should be taken to ensure that the - point is connected to the quartz. The clock is accurate then.


The sensors for Temperature, RLF and the LDR for light alarm got a cable.


Later, I still want the sensors for pH, EC and get tank level.
I still need to look at some things about conversion to PH, EC values ​​me. But that will happen later.
EC, PH values i only use for the Statistic-Graph Data Screen, not to regular my Nutrients.

I have used the opportunity as a rookie from the example Numerous sketches to build something usable. The problem with this method is that the source code is very complicated and somewhat confusing.
I just have to learn step by step. That´s a full Copy Paste DISASTER.

As my Screenseaver i use the nice example code from Henning Karlsen the analog clock sketch.
... to build a nice graphic and finished with gimp is the Screenseaver



In the next days I'll even let the Arduino run a few days. If all goes well I can improve the code until next year. And if I have the equipment for the box together it can go.

...

 

[Curare Widow]

Today I want to briefly show what happens with my sensors.
Now that I've DHT11 sensors and LDR assembled my graph also writes the data to the screen.

But I have seen that I need to adjust so that the values ​​at the end just build another +1. Example at 20 °C, but the graph writes 19 °C ... but that is no problem to correct it. For me as a starter, that's a good result ...

Many hours you have to put with many new things apart, example is the gimp tool.

Here is my Header Code

I have the next few weeks no time to play around with Arduino. I hope there is more time to play again soon

I have problems during the test run with the RTC and Arduino.
The reasons were that I have built the complete power supply via USB. I used a cheap mobile phone charger with USB output during the test run under full load. The Arduino is switched off for safety reasons at 500mA.

I have to use the VIN-PIN if I want to use an external power source without USB or power adapter connector.

The test run is a simulation for the flowering phase. The sensors work well.



Ok, next step is the installation of an external power source. I have found a cheap and suitable here.

Hello all,

Looking good.

I am interfacing my arduino with a windows app that is so far coded in C#. I abandoned VB and C++ for C#.

So far I have communication between the maxim 1-wire devices and the arduino and between the arduino and the windows app. I am able to read multiple DS18B20/18S20 temp sensors, DS2438 battery monitor used for A/D conversion for the humidity, CO2, Boolean devices such as flood, water level and barometric pressure voltage readings and the ds2413 open drain switches.

Thus far I have a working form that displays temperature and humidity. I also have functional control from the app of the ds2413 switches.

I am able to communicate without errors however, there is little int he way of error handling which needs to be addressed.

I have coded a text sending routine through smtp...need on how to control from a remote device (later). Also, I have data logging routine that is functional but still far from ready. Still many variables yet unknown.

Here are some screen shots of a work in progress.

I have C# programming questions that I need answers to. Google is great but sometimes is not enough.

Arduino code thus far...its messy at points and is being worked on.

Hello all,

It can be seen that I need more guidance with regard to my programming skilz

It is a hobby project after all.

Any suggestions as to improving the project are welcome.

[McKush]

subscribed.

I have a number of arduino's lying around that I have thought about using to monitor and control my environment & feeding in my grow area.

Once my room is complete I may use this info to jumpstart my own project so thanks for sharing all!

 

[Curare Widow]

Wonderful, that's nice. Nice to see some action coming into the project.

I'm going tonight to install the new power supply.
I have revised my source code a bit.

I'll make tonight a small package done. Complete with SD CARD files. I hope there is some feedback because I just no possibility to make accurate tests.

I examine now exactly how I could connect the RTC. SQW pin, etc.

 

[Curare Widow]

I have all the files from my SainSmart project. (12MB)
More I can not do. I'm even beginners. Maybe someone has fun on my project. If not, it is I actually do not care.
But have no rights to Upload the file here!

Your hardware must of course match the project hardware.
Pictures of the project are somewhere at the beginning of this article.

Search Something ....

The User @minds_I has flooded my article with his project. My project is something completely different! Maybe he does not know how to build an own article? I do not know ...

Update later ...

 

[minds_I]

Hello all,

Sorry dude, I will take it down if you want...did not mean to crash your thread...thought I was helping in exchange I might get some help coding.
