potentiometers have three connections. the center connector goes to one of the J_A pads on the logic board. the side should go to J_0 (ground) and the other to J_5.
in the photo, red is 5, black is 0, blue is A.
use a low-ish resistance potentiometer, like 1k or 5k.
we suggest adding a .1uH inductor in place of the green jumper wire, which is right next to the usb port on the logic board. this will clean up the analog signal.
now you can send messages:
/box/adc_enable 0 1to turn on the first adc channel. (given you connected the wire to the leftmost J_A) and you’ll get these messages back:
/box/adc 0 0.45which means 0.45 on adc channel 1. range is 0. to 1. float.
