Project developed with Arduino UNO and FSR sensor Force. We can measure the weights of 0.5 to 3 kg with high accuracy. To build it we must consider several things:
- The design of our digital scale and material used.
- Follow a procedure to calibrate the digital scale.
To achieve greater stability in the readings I consider two things: Centralize the object and make a stable design.
