First, we recommend that you check the post mentioned above. It covers the basics of getting an Arduino, the Wheatstone bridge shield and the load cell connected together and testing them to ensure they work. Please note our example uses A1 and the Strain 2 connection on the Wheatstone bridge shield and A5 for the buttons on the LCD/Button shield. Once you have the basic setup of the Wheatstone bridge shield and load cell completed and working, we can move to adding the LCD screen shield.
Then, place the LCD shield on top of the stackable headers. Follow this by using a female / female 1-pin jumper cable and connect the protruding pin from the stackable header to the A5 male pin on top of the LCD shield
Place the stackable headers on top of the Wheatstone shield’s female headers. Make sure to bend the stackable header’s A0 pin towards the outside instead of straight into the female header of the Wheatstone shield .
Once all the parts are assembled, simply connect your Arduino by USB to your computer and start the Arduino IDE. If you do not have the Arduino already installed or have an older version, you can obtain the most recent version here (for Windows, OSX and Linux). Make sure to select the appropriate board type (processor if needed) and port.
