Ah OK. so you're almost as broke as me. If you were to give a brief run down of what options you want available for your user, I'm sure I could knock up a basic menu system that you'd be able to build on.

Hi,

I would like to add a very simple temperature controller to my coffee roaster. Planning to use arduino, ssr, thermocouple, two resistors and connect to my laptop with usb and that's all. I am basically a cut and paste programmer and I have found code to automate ramping, and/or interface with lcd shield with buttons, but I am trying to keep hardware costs down and I want to set up a control panel to output current temp and set temp on my laptop and have inputs to increase and decrease temperature.

I can't seem to find code to control directly from computer, maybe just looking for the wrong thing or not easy thing, but I would appreciate greatly if someone could point me in the right direction, thank you.

[system]

there are two aspects to this project - one is the arduino side and the second is having a control panel.

are you dead set on having a control panel over USB? are you sure thats the best option for you? why not look at alternatives such as WiFi, or ethernet just as starters and then you could possibly interface with a website on your computer instead of having to deal with messy low level serial communications.. in either case, as a "cut and paste" programmer you are probably chewing off more you can handle with this project.

If you want the control panel to be on your PC screen you may be interested in this Python demo.

Another option is to create the PC control panel as a web server app on the PC - then, without further programming, it should be possible to view it in the browser on a phone or tablet. That can also be easily done with Python. I have built this sort of thing for model train control.

Thanks, this looks perfect, but I don't see the file attached to the post???

[system]

I got it sorted, thanks for the help!

They seem to have got lost in the upgrade and I can't upload them immediately.

I will try to fix it during the day - check back later to the post where they should be

I have now uploaded a .zip file to the other Thread
