Spark Fun Electronics

  • You may know what an OR gate is. An OR gate is a logic gate that takes two inputs
    and controls an output. You may have played with these types of gates, even
    possibly a DIP packaged OR gate with 4 OR gates built into it. This DIP package
    required a power pin and a ground pin. Electricity flowed through the IC and
    allowed it to operate. You may not be sure how the IC was built, but you
    understand that if you change the inputs, the output changes. You can do this by
    tying the inputs to either power (also known as VCC) or ground (GND).  You
    probably played with one of the DIP ICs in a breadboard. If any of this is
    completely alien to you, don't fret! We'll try to ease you into it.
