I have an Arduino that I am running two DC motors off of. I have the L298N motor shield that I am using to power the motors. Now that I have the system hooked up and running, I want to add the next step.
My end goal is that I want to create a robotic 'arm' of sorts and write some code that can move the different 'joints' independently. I just want to be able to code an action directly so I don't need functionality where I manually control the movements.
I've been trying to find DC motor 'attachments' or 'heads' that I can build on top of the motor so when it spins, it will move the piece but I can't seem to find anything that fits the little DC motors (some of the heads are for Servo motors). I'm really attempting to build this from scratch so I'm trying not to use any 'kits' and am trying to learn about the different components that would go into building this. Everything I find seems to point me towards a kit or something which sort of defeats the purpose of building it from scratch.
Are DC motors ok for this or should I be looking into something like a servo motor?
Also, I'm aware there is a robotics stack exchange forum but this seems to fall under this a little better because I'm basically just trying to get an idea of what kinds of attachments can go with a DC motor and what exactly I can be using them for.
Thanks for your help!
