Controlling a motor both directions

Projects General Guidance
1

hello, i recently came across a motor that i would like to use for a project. In the project, i want to be able to control the motor to make it spin both directions... I'm trying to think of a way to do this... would i need diodes? or a relay?

any help would be appreciated.

Brushed DC motors usually use an H-bridge (or possibly relays). Below are previous post about h-bridges.

You can use a relay or an H-bridge to do this, see:-
