So like in order to get the LED blinking i had to push the LED into the board the long side which is positive go into D2 the short side which is negative goes into GND then when that's set change the led into Arduino like int led = 2; and keep everything the same the LED should blink.

click and open the video in a new tab to see it that's what i did

So this a diagram on how we set it up. it show how the red wire goes into D2 and black wire goes into GND.

So how I got all six of the LED lights to blink i had to re plug the nano into the board but it leaving one row of the board empty i had to get a wire plug the wire into GND on the left side of the board then plug the other side right beside D12 in the empty space then get 6 LED lights plug one LED into D2,GND then behind that one plug one into GND, D3 then one more into GND , D4 we had to stretch the thing so it could reach GND and its number. then the wired that i plug GND in to D12 that wire was GND so i plug a the LED in D12 , D11 and D10 and stretched the things to GND set up the ARDUINO and all three blinks

So this a diagram how i did the circuit it show how the wire went from GND to the other side of D12. It shows that the LED lights for D12,D11,D10 it reli on the wire for GND
