not more than 10, I am from Norway

https://github.com/terragady/ArdBir I have those ones if you are interested

buy what?

no problem :)

should work, but still you can update it to 1.6.9

I do not think anything about it, just asking if you are using latest IDE for compiling the sketch? I know some previous versions were compiling sketches which were larger

He is using nano as well and his version was optimized for this purpose and he cleaved credits so it should fit. Are you using latest IDE?

you can use joefarmer version, it fits there

you can use your board but just connect relay from the bottom? Can you try this? Here is the doc how to connect it or you can use GTO board to check it out as he is using it on his board. https://www.ghielectronics.com/downloads/man/20084141716341001RelayX1.pdf

basically you do not need this whole module but only relay, then you only need 2 wires from arduino. Now you have two transistors in a circuit so you need to power another one as well.

or you can delete first logo, initial screen etc. I believe pro mini has little more memory if I am not mistaken? Because bootloader is taking less space. BTW I was able to put ArdBir to ESP8266 and it seems to be working fine. I used I2C display for it. But when I am trying to implement some of...

You need something more than 5V to power the Arduino from VIN port. Else you can power arduino via USB or 5V pin (be careful its not regulated here anymore). For the rest 5V should be fine to test.

hi, maybe stupid question, I am not using brewpi but just looked here and seen how its wired. So why do you need arduino if you can use RPi's GPIOs to control relays and get temp probes wired?

If anyone is interested I designed a board for Arduino Nano, 20x4 LCD Here are the gerbers files: https://github.com/terragady/ArdBir You can just do it at your local PCB house or something like dirtyPCB or elecrow for 20$/10PCBs which you can share. So I just used BC337 as the original...

You can adopt some Ardbir PCBs as it will be similar and even easier because you dont have to wire LCD. But I do not know if you would like to have shield for RPi or just connector on the cable. The only problem what I can think off is a power supply, because you need microUSB for RPi and power...

It will be better if it can measure temperature even every second for better control calculation? But Maybe it doesnt necessarily need to save it all, you can save every 10th string for example. And BTW i do not think you should connect SSRs to the GPIOs directly unless you want to fry...

I think its ~1A for IRF530 for 4.5V at 12Vds? (10^0). but still yes I see your point. I would use yours but yours are so small :) So maybe except that I will use some other logic level gate (IRL family?) or something which can handle 5V and does not heat much? Or can you suggest any...

ok right, so maybe I should consider to have some stronger transistor/MOSFET there So on the GTO board/project he is using IRFZ44N MOSFET (Q3, Q4, part list was somewhere in this topic and on ArdBir dropbox), but when i am checking the datasheet there is Vgs 10-20V which arduino cannot give I...

I meant the normal pump output from the PCB (aren't they called srew in terminals? :) ). So just skipping relay. Or I thought I might just use relay as GTO on his board, built it
