Eventually, I want to build a cart to follow me around and power my 12v camp fridge. But there are so many things needed to be decided on before that (like how much beer I will need, etc). And those are discussions for another day.
I’ve decided to use Raspberry - and that seems to be the Holden/Ford debate in the sedan world, or the Toyota/Nissan debate 4wders have: they are both as good as each other, but one has to make a decision. But a decision has been made and I am happy with it. (I have an Adruino Uno but I am about to buy a Devastator Robot platform along with my Rpi 4/4gb.
Yeah, it’s a bit of a gadget/toy, but why not?
My main question is what do I use for a motor controller? I bought a Freetronics H Bridge and it works great with the Uno, but that currently has little way of being able to be controlled. You have to program all the movements into the Uno beforehand and, currently, I’m freaking out the dog.
I have an RPi of unknown origin, bought in the US by my brother-in-law as presents for my nephews. I have zero documentation and they have zero idea as to what model it is (or even how to use it to do anything……) I can’t find any reference to using the Freetronics unit with an RPi anyway.
Hence, I’m about to bite the bullet and buy RPi mentioned above and need some advice.
Can anyone help with a recommendation on a h bridge/ motor controller - preferably from Core so I can bundle it in with my purchaae and not pay excessive postage on what will end up being tiny.
