I am following a tutorial online to make a pong game. I have managed to make quiet a lot work apart from my paddles in the game keep on shaking. The buttons do work fine, up and down on both ends.

I am sure, there is something with the power being supplied and not reaching to all points in the breadboard.

I am attaching a picture of my circuit board.enter image description here Any advice?

Thank you, W


The + and - along the bottom of the picture aren't connected to anything. It also looks like this board has a separate left and right side.

So just make sure everything is connected along the sides.

  • Do you mean, I should supply the + & - from top side to the bottom? – iowaqas Oct 9 '17 at 7:39
  • No. They are split horizonally, in the middle. Both rails, upper and lower. Test continue with an ohmmeter and see yourself – user31481 Oct 9 '17 at 7:44
