I tried to modify the code, and I have tried a few other codes as well with no luck.
I was able to see the values changing in the serial monitor with the “interface to serial code” and I can send messages to the LCD but I’m not having any luck getting it to actively display values.
any ideas how to get this to work?
I have no coding experience and I am brand new to this forum.
I am able to see the values in the serial monitor I can also send the LCD messages through the serial monitor by changing the code a bit, but it does not actively display anything. I do not have a LCD with the buttons and the same pin out as that one. I am using a LCD with only four connections. GND,VCC,SDA,SCL it has the 12c interface chip on the back.
I was hoping someone would be able to tell me how to make the " strain_gauge_shield_and_lcd_arduino_uno_code" code work with this set up.
I attached a photo of the back of the LCD and my current set up. Keep in mind the values displayed, are values in manually entered. The set up is not actually displaying those values.
This is the code that allowed me to send messages to the LCD and also allows me to see the values in the serial monitor. I tried to edit it abit to make it work, so it might be totally mangled.
The negative values probably mean that you haven’t calibrated it, to do so you need to use the setup in the strain_gauge_shield_and_lcd_arduino_uno_code, however, as you mentioned you don’t have a screen with a button you will have to modify the code to have a different input, you could try using your keyboard. To zero it out or get the value in LBS you have to re-calibrate.
You can check this library to have a better idea of what I’m referring to:
