Arduino-Based Coin Weighing Scale with 3D Printed Case
Project Description:
This project start from my laziness and necessity to avoid a repetitive and boring task that I have to do every day in my job: counting all the coin in three cash registers and put the number of each value in a pc program that gaves me the total amount. So i decide to create a little tool to help me and makes things faster.
Components:
Arduino Nano: The microcontroller at the heart of the project, responsible for processing data from the weight sensor and displaying the results on the LCD
LCD I2C: A 16x2 liquid crystal display that uses the I2C protocol to interface with the Arduino, showing the weight of the coins in real-time.
HX711 Weight Sensor: A precision 24-bit analog-to-digital converter used to measure the weight of the coins with high accuracy on a 1kg weight max
3D Printed Case: I like to complete a project with a good case desing. I'm not a designer expert, but with practice i'll hope to create looking good case. Custom-designed to house all the components, ensuring a compact and sturdy final product. Anyway not perfect
Goal:
The main goal of this project is to provide an educational tool that demonstrates the principles of electronics, sensor interfacing, and programming. It allows learners to understand how to connect and program various components, read sensor data, and output information to a display. I hope this hands-on project encourages problem-solving and creativity in designing and building the case and integrating of all components.
