# 8. Input Probing
This week for group work we needed to probe an analog and digital input device using an oscilloscope. For our analog input we chose to use a potentiate. We wired everything up and then intercepted the signal wire with the probe. Once we had everything wired, we started testing, During our testing, we weren't able to adjust the axis to get a smooth curve but were able to see that the value was increasing and decreasing as we adjusted the position.

For the digital input we tested it with a button. We wired the probe to one side and then grounded it on the other. When the button was pressed we could see the signal passing through. It would become a straight line when low and then would show some waves when the button was high. We finally found a way to adjust the axis so that we got distinct waves.
