I'm using an op-amp (LM358) to voltage follow a high impedance sensor and my question is this. What do I need to do on the op-amp output side to connect it to an Arduino analog input to read the voltages safely without burning anything up? Do I want to throw a resistor in between the op-amp and Arduino?

Thanks ahead of time.
