Hey Teena,
Just before you jump into grabbing some solder from Bunnings there is a difference between the stuff used in plumbing/glass work and electronics, there was a good discussion here: Feather M4 Express and NEOPXL8 M4 Featherwing problems - #4 by Phillip128696
In short it would be better to grab some solder such as this (Also my personal favorite): 1mm Lead Free 250g Roll Solder Australia
Some of the irons there look pretty decent, Iām keen to see how you go!
