This is how to make a USB power supply for a breadboard without breaking the bank. The reason I made this instructable is because when I make projects on my breadboard, my batteries would keep on dying. So I thought to myself and I came up with the idea to use a USB to power my breadboard indefinitely. NOTE- I am not liable if your circuit backfires and destroys your computer.

Step 1: Obtain a USB cord
This is pretty straightforward. Just use a USB that you don`t use anymore, or you could buy one for about $3-6 USD
