4-Bit Adder Circuit

What to Expect:

Each LED represents one bit in a four-bit string (a nibble.) Each bit that you turn on using the LED’s corresponding switch will turn on both the LED and create an “ON” signal to the pin it goes into. Depending on what LEDs, the addends, are on will determine the LEDs on that are the SUM.

How it Works:

Flipping the switch to any addend in each of the 4-bit binary numbers will light the corresponding LEDs' position. An on LED represents its binary number in the 0, 1st, 2nd, or 3rd position.
Along with each of the addends LEDs turning on, the SUM LEDs will also turn on. The lights that turn on in the SUM will be the binary addition of the addends in the 0, 1st, 2nd, 3rd, and carry (4th) position.
The 74283 4-Bit Adder IC is designed to have 8 inputs that go through a series of logic gates to have four outputs and a carry. These are a series of AND, NAND, NOR, XOR, and NOT gates. The 8 inputs are one from each bit location from the addends.
