Are you looking to build your own Arduino weight machine? Look no further! In this step-by-step guide, we will walk you through the process of creating your very own weight machine using an Arduino board. This project is not only a fun and rewarding DIY endeavor, but it also allows you to track your weight in a personalized and unique way.

What you will need:
– Arduino board
– Load cell (can be bought online or at your local electronics store)
– HX711 weight sensor module
– LCD screen
– Breadboard
– Wires
– Screwdriver
– Tools for soldering

Step 1: Connect the load cell to the HX711 module
Start by connecting the load cell to the HX711 module. The load cell will measure the weight, while the HX711 module will amplify the signal to make it easier for the Arduino board to read. Connect the red wire from the load cell to the E+ pin on the HX711 module, the black wire to the E- pin, the white wire to the A- pin, and the green wire to the A+ pin.

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

Step 3: Connect the LCD screen to the Arduino board
Connect the VCC and GND pins of the LCD screen to the 5V and GND pins on the Arduino board. Connect the SDA and SCL pins to the A4 and A5 pins, respectively.

Step 4: Upload the code to the Arduino board
Download and open the Arduino IDE on your computer. Copy and paste the code below into the IDE:

Upload the code to the Arduino board by clicking on the upload button.

Step 5: Calibrate the weight machine
Place a known weight on the load cell, such as a 1kg weight. Check the reading on the LCD screen and adjust the calibration factor in the code until the reading matches the known weight.

And that’s it! You now have your own DIY Arduino weight machine. You can customize the code to add features such as tracking weight over time or setting weight goals. The possibilities are endless with this project. Have fun experimenting and happy building!
