In this project i will guide you how to make a digital scale using Arduino uno and some other items
This is a very easy to do project
Step 1: Items Required
3. LCD display
4.Couple of jumper wires
Step 2: Connecting Everything
Just take look at the diagram given above it shows you how to connect the LCD with the arduino.
You may skip connecting the potentiometer it is not necessary.
Now connect the ultrasonic sensors vcc to arduino's 5volt.
then trigger pin to 6th digital pin of arduino.
Echo to 7th digital pin of arduino
and Gnd to gnd of arduino.
Step 3: Code
Given above ino file is the code to be uploaded to the arduino uno.
It is also given in a text document.
