Building a DIY Arduino Scale with Load Cell Sensor


Building a DIY Arduino Scale with Load Cell Sensor

Are you looking for a fun and useful electronics project to work on? How about building your very own Arduino scale with a load cell sensor? With the help of some basic electronics components and a little bit of programming, you can create a customized scale that can be used for a variety of purposes.

In this article, we will guide you through the process of building a DIY Arduino scale with a load cell sensor. This project is perfect for beginners who want to learn more about Arduino programming and electronics.

To get started, you will need the following materials:

– Arduino board
– Load cell sensor
– HX711 amplifier
– Breadboard
– Jumper wires
– LCD display
– Power source (e.g. battery or USB cable)
– Enclosure (optional)

Once you have gathered all the necessary materials, follow these steps to build your Arduino scale:

1. Connect the load cell sensor to the HX711 amplifier. The load cell sensor will have four wires – red, black, white, and green. Connect the red wire to E+, the black wire to E-, the white wire to A+, and the green wire to A- on the HX711 amplifier.

2. Connect the HX711 amplifier to the Arduino board. Connect the VCC pin on the HX711 to the 5V pin on the Arduino, the GND pin to the GND pin, the DT pin to digital pin 2, and the SCK pin to digital pin 3.

3. Connect the LCD display to the Arduino board. Connect the VCC pin on the LCD display to the 5V pin on the Arduino, the GND pin to the GND pin, the SDA pin to analog pin 4, and the SCL pin to analog pin 5.

4. Write a simple Arduino sketch to read the weight from the load cell sensor and display it on the LCD display. You can find sample code online or write your own code.

5. Upload the code to the Arduino board and test your scale. Place an object on the load cell sensor and check if the weight is accurately displayed on the LCD display.

6. Once you have successfully tested your Arduino scale, you can add more features such as calibration settings, unit conversion, or data logging.

Building a DIY Arduino scale with a load cell sensor is a fun and educational project that can be used for various applications. Whether you want to weigh ingredients for cooking, measure the weight of small objects, or build a mini weighing station, this project is a great way to learn more about electronics and Arduino programming.

So, gather your materials, follow the steps outlined above, and start building your very own Arduino scale today. Happy tinkering!
