I'm a new Arduino user. I recently got one of these 4-digit 7-segment displays:
It came with a LED backpack. I had two questions about.
- Is it possible to test it out w/o soldering? Can i plug it into my breadboard?
- What is the purpose of the LED backpack?
- What is some good beginner soldering equipment?
If i have to get some soldering items, i will. But if possible i would like to try it out now.
I noticed this similar display is shown in the preview pictures being straight attached to a breadboard.
Which makes me wander about the purpose of the LED backpack and if they are possible different.
