I have a small project that needs to be done. I need it to be done ASAP. I have strain gauges that I set up on a Wheatstone bridge. Other than that, I also have INA125P to amplify the signal from the Wheatstone bridge output. The data then will be read in an Arduino.
1). I have a blade that I installed in a cantilever beam position.
2). I will install the strain gauges on the blade. (Half-bridge Wheatstone bridge).
3). Once the blade bends downwards or upwards, it will give us a positive and negative reading.(This is because the Wheatstone bridge is inbalance).
4). If the blade moves downwards, it will give a positive value to Arduino. and when the blade moves upwards, it will give us a negative value.
5). Imagine 0V = 0 in Arduino. 5V=1023, -5V=-1023. On the other hand, I need to read the full differential voltage.
If you think that you're suitable for this job, do contact me. Please, no time waster.

Hello!I am ee [url removed, login to view] your informarion arduino don't read negative voltage ,you need to scale up the negative to positive .Means make voltage divider to make -2.5 to 2.5 to 0-5 [url removed, login to view] this way readigs from 0-512 are Thêm
