I am making myself a setup in Obsidian to help organize myself. However, I am unsure how to create checkboxes in my lists. I tried using - [ ], and it did not appear to work.
Also, I am unsure how to efficinetly set things up for maximum effictiveness. Any advice would be apprecieted.

I am making a setup with a phototransistor to measure light levels (I am just starting out with Raspberry Pi), and I am currently seeing if I can set up a switch to have the light detector only on when the switch is depressed. From what I understand, the white wire is responsible for measuring the voltage that changtes according to the light level. However, when I attempt to use the setup on the 4th image (with the same code), the sensor appears to give widely varying readings, and only appears to respond to the responses when the wire is not plugged in.
The setup works normally when the switch is not plugged in (Image 2), and the pins (Image 1) are the same in all cases.
