Creating a reaction in the arduino ,

I have followed 'Aatik's lab'  instructions on making a conductive paint light switch.

I bought the components, the 5v relay ,arduino  uno , wires , led and the 5v power stick. I connected the wires from the Arduino to their assigned places in the relay and then on my laptop I downloaded the touch sensor code placed it into ide , although I had difficulties placing the libraries at first.

So I watched some more tutorial videos on how to properly export library’s into the arduino ide software and learnt that there were about 3 good methods.

After this I exported the code into my arduino uno and then connected the wire pin on the number 6, position on the arduino onto my sheet of paper that had conductive paint.

I realised that everyone I now touched the paint there would be a flicker on one of the arduino lights , and I tested that again and again getting the same reaction.

Now my next thing is to attach led successfully into the relay , the ones I used I did not sufficiently attach them so I need to learn how to do that better.
