Source code for measuring weight (load cells)

The application should measure weights up to 200kg, through 4 load cells of 50kg connected to the HX711 module. The code must run on NodeMCU.

Attached photos with mounted scale.

The scale should start by informing the current weight on the scale. With known initial weight, the weight of the cylinder informed by the user must be subtracted.

The IDE Arduino Console should display:

1. Current weight on the scale

2. Bottle weight (informed by the user)

3. By net mass (informed by the user)

4. Total weight of gas in the cylinder ([login to view URL] weight on the scale - 2. Weight of the cylinder)
