Introduction: How to Make SINONING Arduino Scale With Source Code
This is a kit can be applied to real life. If you need more accuracy, or more range, you can be based on this kit, use more reliable sensors, make more powerful scale. Through this kit of learning, you can understand the principle of electronic scale. when you get this knowledge, you will find so many fun to learn arduino. and you will get confidence, you can go further.

and you can buy the whole kit from :here
Step 1: Featuer:
* No welding required * Online Graphic Tutorial * Provide source code
You can modify the code so that the display you own name,
after you finished this simple kit, you will get self-confidence, you can go further.
Step 2: List
Arduino UNO China Edition* 1
10kg acrylic frame *1
LCD 1602 + IIC display *1
Hx711 *1 Weight *1
Online tutorial Source code download
Step 3: Connect 10kg Pressure Sensor Frame
just following the photo
Step 4: Connect Hx711 to Arduino
connect hx711 to arduino uno
HX711 ----- Arduino UNO
Step 5: Connect Arduino to LCD1602
connect arduino to LCD1602
GND ———— GND
VCC ———— 5V
SDA ———— A4
SCL ———— A5
Step 6: Source Download
download the source code to learn advance.
hx711 library for arduino uno
Step 7: Advanced Play-adjusting the Scale
adjusting the scale
change the file :arduino library/hx711/HX711.cpp
Weight_Shiwu = (unsigned int)((float)Weight_Shiwu/4.65+0.05);
change the figure 4.65, if the reading more than the real weight, increase the figure, vice versa.
