I’m recently using ubidots as an application server for my project. i’m transmitting my data (increasing data) in one variable. In that, i need to get differential value (i.e current value - old value).
For this what kind of synthetic expression may i use?
Eg : my data = 120 …150 , 180
I need to subtract the latest one by past data (180 - 150) to get my value as 30.
Can anyone help me out with this issue?
Thanks in advance!
