Hi cyclegadget,it is possible to "read" the output of the LM358 with the arduino linking the communication wire to a pin (analog pin i presume)? with which function?
thanks again
The first requirement is that the voltage must be positive in relation to ground and 5volts or less. I would check it with a volt meter before hooking your Arduino to it.
Given your data shown, it sounds like the output of the 358 is serial communication. As said before, I don't know baud rate and other parameters. If you can you need to find out how other people have connected to the device to get their information.
Good luck!
