DIY CHEAP DIY microcontroller (arduino) grow room environment controller

[jackmc]

I've started reading and await the parts list. Thanks for sharing Ksj!

Ksj, which Arduino microcontroller board should I buy? Can the board be used to control multiple functions or do you need one for each function? Could I control PH up and down with one board and two pumps or PH and nutes?

NICE
Its always easier to develop something with more people to ping pong with
1 arduino can handle it all. also ppm if you whould go that far :smoke:

The arduino leonardo can handle it all.
i have 3 of does working 24/7 and they work flawless.. also the china copies
Lets figure out how many io ports we need first....Remember i do not have anything down on paper
So bare with me please

I`ll try to break it down from the top of my head...


Well we need a menu to make changes to the arduino.. whit out hooking it up t a computer
This can also be made with out it.. but that´s no fun is it..:smoke:....

Im oldchool and do like flipswitches...to trigger the diff. functions

one switch needs one 1 io port
1 io port for toggle main/settings
1 io port for toggle settings / ph
1 io port for toggle ph values up / down

1 io port Ph shield
2 io port 2. solenoid dosing pumps (ph up / ph down)

1 io port Ppm shield
2 io port 2 solenoid dosing pumps (ppm up / ppm down)


1 io port for temp sensor..temp compensation for correct reading

The ppm do not need a setting for changing values.
This will be handled by algorithm (basic math)

10 ports thats it.. the arduino leonardo have 22 io

Wohoo we have 12 io left what to do.... lets tinker about it..

Dumb our res and refill hmmmmm maybe..
Endless possibilities

This is the layout of io port.

I´ll do the parts list later today...
Menu is finished and tested. be back with it later also

So I'll get the Arduino Leonardo! What type relays, peristaltic pump, a bridge and resistor, some wire and a breadboard? The instructable you linked to used a battery to power the system. Do you use a power supply? Can I use 1 power supply to power everything?

This should answer your questions

:smoke:

Just to get everything clear ATM i DO NOT WORK ON THIS PROJECT..
Nore do i have anything to work with.
I broke my ph shield (cheap china shit) and my code is also gone.... Square one...
Left me with a ph probe and a dosing pump..+ arduio boards
But might be finished before spring..

BUT the project im currently working on.... SOIL PROJECTS.
1.Will have the same base menu.. Exatly the same
2.Use the same scematic for the mosfet. NOT DONE YET

I have not worked out the scematic YET.. waiting for parts..
There are many ways to do the mosfet. I have no experience with fets. But when done il make scematic..

These are the parts i have chosen to TEST
schottky sr5100
diode in4007
mosfet RFP30N06LE
some different sizes resistors

So looking at some at the different scematics on the net
A couple of resistor and it should work


Parts list

Ph shield / ec shield
Theres a few to choose from..

https://www.sparkyswidgets.com/product/miniph/
e.t.c.

I like to support the common man..
and i been following along this dude for a while now.. This will be my choice.

Dormant labs…ph shield..
I DO NOT HAVE ONE SO CAN NOT GIVE ANY HELP
THIS IS EXTREMLY IMPORTENT FOR ME TO CLARIFY...

for the rest

Arduino leonardo
1602 lcd with i2c
A bunch of jumper cables for testing
breadboard for testing
flip switches … 3-10 depends min 3
12v power supply 1000ma is enough
lm317t voltage regulator 12v to solenoid valve 7-9v to arduino
Arduino can run on 12v but i don`t like it...
Link to info about the lm317
http://www.reuk.co.uk/LM317-Voltage-Calculator.htm
2 12v 500ma peristatic dosing pump...

I bougt all my part from china..alot cheaper...disregarding my broken ph shield :slaps:

lets work out the ph first.

Menu for arduino

Well
I finished the "base" menu its "universal"
Settings is triggered via button state.
Link til arduino
Hope this info will help
http://arduino.cc/en/tutorial/button
http://playground.arduino.cc/Code/Function
http://arduino.cc/en/Tutorial/LiquidCrystal


Trebranch: example
MAIN/system/Setting/1/2/3/4/5

This is just the base and can be triggered via 2 buttom states
1 button toggles = system/setting
1 button toggels = setting/1

Att.
is sketch and library for lcd 1602 ic2

Had some sparetime today

So i looked at the mosfet circuit.
schematic
http://bildr.org/2012/03/rfp30n06le-arduino/

mosfet RFP30N06LE
560 ohm puldown resistor

I´ll hook it up tomorrow with the sr5100 schottky across the rails (solenoid )

with the solenoid valve 12 500ma.
leave it for 24 hours triggering on / of cycle.. se how it goes

and then try out the 12v 500ma peristatic dosing pump
and do the same

2 different power supplies tho..

Rule #1 in anything computer: BACKUP!!! LOL!

 

[KsjAuto]

Really :no:!!!:thumbs:

Well shit happens sometimes.
No biggy..
Should not be that diffucult to setup again.

One thing at a time...
its the EMF theres a problem.. arduino will fuck up... trust me on that one.. fried a io port and burned a relay...It went up in fire not a joke...

Don't know if this will help in this environment but...

Try isolating the brain from the relay/mosfet/etc with a quad-bilateral switch (non-inverting)and wire the output with light-duty fusible link or just a regular low amp fuse. That'll give you 4 switch channels each to play with and a little over-current protection. I build digital switch networks for my guitar stuff (foot board). Still trying to learn midi-based automation.
