, breadboard is configured to have the power from battery. Then positive is connected to the positive line. After that LED and are connected to the main input just to make sure there is power. Next the transistors are connected to the breadboard and connected vertically because horizontal lines are connected. Then bottom N type end of the transistor is connected to negative. In addition resistors are connected to the other N type end and to positive, also connected to P type to positive. The most importantly everything are put together.
