How can I safely step down voltage for my project?

[Anthonytsi]

Hello.
After browsing the internet for hours asking general electrical questions I have decided to go straight to the ppl who know.
I can solder and tell the red wire from the black. Thats about it.
I hope to learn more on this forum.
Thanks.
