Breadboard

Breadboard is a current distribution board used for circuit prototyping. It should be used to test your circuits with Arduino or RPi before you start to make a Perfboard or a PCB. There is a big divider in the middle and it separates the Breadboard into two. Both sides have their own GND and Positive voltage which is connected as shown with the blue and red lines, it is possible that these lines are cut in half meaning that they will not transfer the current from one side of the breadboard to the other. The columns market with letters are connected only vertically, for instance from A to E. Columns in relation with each other are separated.
