Load Cell Bricklet
==================

.. note::
 This Bricklet is currently work-in-progress!


Features
--------

* Measures output of load cells
* Integrates 24 bit ADC for high resolution
* Up to 80 weight measurements per second

Description
-----------

The Load Cell :ref:`Bricklet <primer_bricklets>` can be used to
extend the features of :ref:`Bricks <primer_bricks>` by the
capability to measure load cells.

A load cell that is connected to the Bricklet can be easily calibrated
with only one known weight. It is possible to measure
weight differences of few grams in objects that weigh many kgs.

Load cells with different weight ranges are available in the shop:

* `x - y kg <TBD>`
* `x - y kg <TBD>`
* `x - y kg <TBD>`
* `x - y kg <TBD>`

The Bricklet does have an LED that can be turned on trough the API,
e.g. to show that a weight measurement is in range.
