Adds a load cell to the filament spool holder of a Creality Ender 3 Pro 3D-printer to measure weight and display on TM1637 LED display. Uses ATtiny85 microcontroller and HX711 module for weight measurement.
A load cell measures the weight using strain gauges. The difference between the length of the load cell at one side of the cell will help in determining the weight that is applied to it. This will change the output impedance. The output impedance is integrated into a Wheatstone bridge where the difference of the output impedance determines and c…
