| Jan 5, 2020 at 8:58 | comment | added | Nizam mulk | @Peter Paul Kiefer thanks for replying! well that sucks lol I am thinking of using these batteries but i dont know how to connect them the 9v block battery is only for powering the uno device but I still haven't figured out how to connect the lion or lipo to the motor is there a way I could use rechargeable batteries and plug the uno directly into a dc power source without the use of any batteries. Or if you can help with a new circuit diagram and codes? I would appreciate it. Note all of the products I bought are Chinese apart from the uno. | |

I don't know whether it is a MOSFET or a NPN, so the impedence might not be enough for a PIN13 that has to drive the on board LED also. And you are complete right: If it is a MOSFET even PIN13 would work. | |
