Some information is needed:
- what voltage range do you want to measure?
- show your python program. Use code-tags for source code, see viewtopic.php?t=84477
- show your setup. Either a clear photo, or a schema how the components are wired.
When measuring voltages larger than the 3.3V GPIO voltage of the RPi, you need to either scale down the input voltage of the ADC MCP3008. Or operate the ADC with 5V and manage to connect the 3.3V GPIO to this level.
