Quite complex circuits can be wired onto the breadboards.

You can use more than one IC on the breadboard too.

These circuits work better if all the input pins are connected to 1 or 0.

The output pins can be connected to an indicator (resistor and LED) or the input of another gate.

The NAND into NOR gate circuit uses up all the pins.
