Smart Coffee Scale

Projects General Guidance
1

Hey guys,

I want to modify my coffee grinder to have it start via an arduino board and stop at X gram using a scale attached to my arduino board. I am a software engineer and I know how to use a soldering iron, but i see this project happening only when i take the easiest route possible (because of the time i have).

I want to ask if you can suggest me any conplete scale / arduino kit with which i can

  • measure weight to the tenth of a gram
  • weigh up to a kilo ( the portafilter of my espresso machine is 650g)
  • have the scale connect to an arduino board
  • connect to the grinder with a simple i/o cable
  • connect to the arduino wirelessly via bluetooth (or wifi) to set the desired g and start the grinder via an app

Do you have any recommendations for a kit i can use as a base to start from ?

Thanks,
Lukas

I have not see this as a kit.
IMHO, buy a kitchen scale, either try to hack it and use the information, or add your own interface.
I think both are above a beginner level.

there are a few sites that talk about hacking an Arduino to a kitchen scale

.1 gram? A powder trickler may be useful.

Hi there,

What you can use is a weight scale/bar or how it's called, build you own weight scale
platform and use arduino to calibrate it 1st time, then just receiving the actual weight
of the object/liquid will be on the platform.

After that it's easy just get the data and timing to make your coffee/tea.
