# coffee-scales
[![Build Status](https://travis-ci.org/mortenfyhn/coffee-scales.svg?branch=master)](https://travis-ci.org/mortenfyhn/coffee-scales)

Digital kitchen scales, mainly intended for pourover coffee. The current prototype looks like this:

## Features
* 1/10 gram accuracy.
* Fast settling time.
* No measurement jitter.
* Timer that starts automatically when you add weight.

## Hardware
* A 1 kg straight bar load cell connected through an HX711 load cell amplifier.
* Two 4-digit 7-segment displays driven by TM1637 LED drivers.
* An Arduino Nano, might get replaced by a suitable MCU.

## Build and run the code
Using PlatformIO is easiest:
* `pio run -e feather328 -t upload` (change `feather328` if using a different device).
