Hello! I don't think they mean the same. Maybe they could in some situations, but I can't think of any.

'Soy' is the present form of the verb 'ser' for the 1st person of singular. The direct transalation to English is 'am', like in 'I am'. 'I am Pachanan' would translate to 'Yo soy pachanan'. You could also say, for example 'Yo soy alta' (I am tall) or 'yo soy una estudiante' (I'm a student).

On the other hand, 'me' is a little bit more complicated to explain (I'm realizing this only now). This is a total amateur explanation, but I think is another way to say 'yo' in situations when something is happening to you, or you're feeling something, and you don't use 'yo'. If your have a belly ache, you say 'me duele la panza', if you like music, you say 'me gusta la música'. And when something is happening to you, like if you're losing hair and getting bald (?) you say 'Se me cae el cabello'.

The use of soy is pretty straightforward, but I suggest to you to look for 'when to use me in spanish' in google.

La explicación que te da martinshaila acerca del verbo "Ser o estar" es la correcta.

Es algo complejo la explicación con la palabra "me", porque el uso de esta palabra cambia gramaticalmente. Voy a intentar darte una breve explicación:

- *Me, como pronombre de primera persona masculino y femenino en singular, realiza la función de complemento directo e indirecto:

"Me han comprado unos zapatos". "Me acuesto temprano".

- *Me (complemento indirecto), ¡tráemelo!, me lo entregó.

- *Me (uso enfático), se me ha perdído el cuaderno.

- *Me (uso reflexivo), me lavé la cara, me voy.

There aren't diferences between 'me' and 'Soy' Those are the same meaning.
