How to power a LED light with a button but without a breadboard?

Other Hardware LEDs and Multiplexing

I have an Arduino R3. I have done a lot of research but sadly i have not found anything useful. Maybe i suck at looking but i came here to ask for advice.

What is your problem exactly?
Could you please draw a schematic?

Hi!
the breadboard allows you to set up an electric circuit (here, wiring up your UNO and components) without the need of soldering.

As a led and a button will take 2 wire each (let's say power and ground or power and digital input), you have 2 basics solutions:

  • Solder the led and its resistor directly to the arduino pin, same for button; EDIT: (strongly not recommended, or you are in your final set up)
  • use a breadbord to mimic the soldering.

For Uno you have a third solution - use the sensor shield like that:

:+1: good point.
my secret third solution was put all the set up into water and hope conductive effect will bring electrons to the correct pin.
