My question is that if the Arduino Uno only has 1- 5v pin, and I want to power the Arduino with let's say a 5v power boost 1000, if I plug and power the Arduino with the power boost then im all out of 5v pins to do my projects. I have tried sticking a metal header into the 5v and then tap off of it with alligator clips but it is pretty ghetto.
Make a 1 to 2 (or more), Y cable wire.
