i try to connect Differential Amplifier with arduino. Finally i connect all wire success, But when I program I don't know Library of Differential Amplifier for Arduino. Help me please.
This is a Differential Amplifier that i use.
Why do you need a library? To get the voltage output from the amp connect the output to an analog input and use analog read like so:
float volts = analogRead(inputPin) * (analogReference / 1024.0)
The value of analog reference depends on the model Arduino that you are using and the setting of the analogReference.
Be sure that the analog input never sees more than Vcc + 0.5 volts or -0.5 volts from ground or you risk damaging the Arduino.
okay thank you very much
