Another tutorial, explains how to use the NXP PCF8591 ADC/DAC IC. [image] Tutorial – Arduino and PCF8591 ADC DAC IC Have you ever wanted more analogue input pins on your Arduino project, but not wanted to fork out for a Mega? Or would you like to generate analogue signals? Then check out…

Thanks for the link... But since we don't have an oscilloscope, are there any other tutorials without oscilloscopes?

one could connect the analog out to an analog port of the Arduino. Then check if the configured value is also measured by the Arduino's ADC

That's a great idea. Thanks robtillaart for the quick tweak. :slight_smile:

You're welcome, @tronixstuff , you could add the idea on the blog :wink:
