Portable Arduino Weighing Machine with Set Weight Option for Retail Packing
Digital load scales are another miracle of modern-day engineering and design. Yes, we are talking about the weighing scale we often see in most of the grocery stores and other places, but have you ever wondered how a weight scale work? To answer that question, in this project, we are going to take a look at the load cell and its working. Finally, we will be building a portable Arduino-based load scale with the HX711 Weight Sensor, which can measure weights up to 10kg.
