What controller is right for me?

by carter840 on Wed May 31, 2017 11:25 am

Hi All,

I'll start by saying that it's been years since I've programmed anything. I apologize upfront that I will be slow with understanding at first, but will work hard to follow along. I am working on a particular project and am looking for suggestions on what to use for the "brain" of my project. Essentially this is for a water chiller/pump. Below are a descriptions of the sensors and functionality that I'm looking for.

General description:
Connect to a OLED or better yet a touchscreen interface, I would like the user to be able to select ideal temperature for the system and a pressure threshold
WiFi connectivity (when pressure reaches user set threshold push alert through WiFi connection)

Specific sensors/controls needed:
Receive data from a pressure transducer
Receive data from thermo-couple
Control Peltier cooling device based on user settings and temperature readings
Possibility to regulate pump's pressure by regulating supply voltage
1 additional sensor input for future expansion (optical sensor or RFID most likely)

So with the above description what types of controllers are available that might meet my needs?
Thank you

Thanks for the prompt reply, what about the below item. Could you explain why you're suggested products might work better?

That's the same processor used on this Feather:

but that board is geared more toward developers. You can use it if you want, but just know what you're getting into.

Another approach might be to base it off a Raspberry Pi. You'd likely need some additional hardware to interface to the various sensors you've outlined. But there are displays available:

Thanks again. I think I've decided on the HUZZAh ESP8266, with OLED board.

Can I used the Feather wings OLED display board on the non Featherweight ESP32 (linked below)?

Probably. You'd want to check out the schematics for the two products and figure out how to make the connections between them.

was not sure where to post my question but here it goes.
on my model aircraft carrier i have 18 gunturrets all with a servo in it, i want to control these 18 using 2 channels of my Fr-sky X9E transmitter, the 9 turrets per side are divided into 4 groups.. port side (left) 2 & 7 and starboard side 3& 6 i want the servo's to all make no more then 180 degrees but want them all to focus the endpoint on a central point..so all 9 port servo's for example aim at a point say 49 degrees of the centerline of the ship. i have lots of space inside the hull (its 6ft10 long) and use hobbyking micro servo's inside each gun turret.
i cant supply power through my receiver to all 18 servo's.. my receiver can't handle the current drain but i can put a dedicated 5v powersystem into the hull.

any suggestions on what hardware to use ?
this is my 1st big multi-channel project and after this is done i have several more ships that need multi-servo controllers .

what would be even nicer is if there would be a way for the servo's to "follow a target" .

@Krijn34 Please start a new topic for your question. It looks like this is a general question, so the "General Project Help" forum might be a good place:
