Hello everyone!
I am using an Arduino UNO to get analog readings from 2 sensors. Then, I am sending the product (*) of these 2 values to a NodeMCU via serial communication. The value is received correctly: when I use

Code: Select all | TOGGLE FULL SIZE

Serial.write(Serial.read())

correct values are displayed. However, when I move the value received to a variable then print it:

Code: Select all | TOGGLE FULL SIZE

x = Serial.read()
Serial.println(x)

different (wrong) values are shown. And these same wrong values are uploaded to Adafruit IO.
So, does anyone know what's happening? Any format or data size differences? Why am I obtaining wrong values? And how to get the correct ones?
Thank you

What language are you coding in and what is the type of x? There is probably some incorrect casting/coercion happening.

Yes right thank you, I had to use parseFloat().
