So I've managed to get the MCP3008 working as a voltage meter with the Pi. Yay :) First off, thanks to everyone here who has been helping me the past two weeks.
Now as for what I am having an issue with at the moment. The device I am measuring the voltage on seems to have an interesting way to send out it's votlages.
When I compare the output from the ADC to a multimeter reading, I can only assume that the ADC is much more sensitive to votlage shifts than the multimeter. This is because on the multimeter, I can see it holding a steady votlage (say
0.75V) while the ADC readout is going up and down around the ballpark area of that votlage (so I'll see
0.80V, then back down to
I want to program it so that the numbers look more stable, but I am not exactly sure how to tackle that. Should I create an array of recent values and just check them against the new one? I tried slowing down my sample rate, but that only made it look even
