Hello there,
I'm busy with a project where I want to import a signal(0V to 5V dc) out of a gas analyzer to one of the analogue inputs of the arduino. My question is: Can I directly insert the output cable of the gas analyzer to the analogue input of the arduino or do I have to make use of resistors or optoisolators or such?
Hopefully someone can help me this (probably simple) question?
thanks in advance
