Look into either finding a different potentiometer, or buying motors with them built in: https://www.amazon.com/dp/B08DKJT2XF/ref=sspa_dk_detail_5?psc=1&pf_rd_p=88097cb9-5064-44ef-891b-abfacbc1c44b&pf_rd_r=P8T0G5Z2JJBEC1RA7ARV&pd_rd_wg=bfS4c&pd_rd_w=VijJg&content-id=amzn1.sym.88097cb9-5064-44ef-891b-abfacbc1c44b&pd_rd_r=0d7f9f4c-93a6-4a7f-9a0b-f7e008a9b313&s=hi&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw&smid=A1RXNZT4AK0KHN&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFFVzg0NFNWSldZQVomZW5jcnlwdGVkSWQ9QTA2NDYxMTJDV0M0N0hYVzkyVDAmZW5jcnlwdGVkQWRJZD1BMDkyNjM0ODFYUTZLQ00yVllUUUkmd2lkZ2V0TmFtZT1zcF9kZXRhaWwmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl

Possible Potentiometers: https://www.mouser.com/c/passive-components/potentiometers-trimmers-rheostats/potentiometers/#:~:text=A%20potentiometer%20is%20an%20adjustable,of%20current%20to%20the%20circuit.

Constraints: 40 mL to 44 mL, anything that can fit in it. The smaller, the better. Rotary potentiometer -> transition from 330 to full 360 degrees of rotation through Continuous Potentiometer. old one is: GA-12DC motor Find something with a smaller encoder stack Test the power and torque of the other two motors. Are they worth it? Try to get everything done by April

wired up the motor that has an encoder on it, think i wired it correctly but cant read any data.
