I am joining my nephew and sister for a camping trip but I have never been camping before what will I need to have a fun and safe trip ?

it will be for a weekend trip and it will be during December so it going to be extremely cold ! I want to make sure I have everything I need but I don’t want to surpass my $200 budget .

can you give me a list of everything I will need to take for camping on this trip

weekend trip, hiking to campsite, $300-600
