SINONING Arduino 10kg Scale diy education kit
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.
* No welding required
* Online Graphic Tutorial
* Provide source code
You can modify the code so that the display you own name,
UNO version parts list:
Arduino UNO China Edition* 1 (we already upload the right code)
10kg acrylic frame *1
LCD 1602 + IIC display *1
follow the clear photo connect the wire, the scale will working.
connect pressure sensor to hx711
connect hx711 to arduino uno
HX711 ----- Arduino UNO
connect arduino to LCD1602
GND ———— GND
VCC ———— 5V
SDA ———— A4
SCL ———— A5
power on the arduino board, you will read the reading. it will be zero.
step two, download the source code to learn advance.

hx711 library for arduino uno
step three, 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.
