Arduino Pong game Circuit Board Troubleshoot 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. Any advice?

Thank you,

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.
