Video Description:
How to build digital logic gates using individual transistors is discussed in detail. The logic gates are built on breadboards using transistors, resistors, LEDs, and different color wires. The truth table and circuit diagram will be shown for each logic gate. In many cases, there is more than one way to build the logic gate so multiple configurations will be shown.
The types of logic gates that are built and tested are a switch, inverter, buffer, AND gates, NAND gate, OR gates, NOR gate, XOR gates, and an XNOR gate. At the end of the video, I also demonstrate how to properly wire up AND logic gates on a breadboard using integrated circuits.
All of the logic gates are built with 2N2222 transistors and the circuit is powered with a 5-volt power supply. The positive wires are red, the ground wires are black, and most of the resistor values are 2K.
