Start your 4bit binary adder by using 4 buttons as the binary inputs and 4 LEDs to indicate the input bits. Note the 5\"\" led is the carry output. {Co} The buttons toggle the LEDs on and off. When the rst binary number is displayed on the LEDs the EnterfAdd button is pressed, the LEDs return to ready for the next binary number to be entered. The first number is stored. The second binary number is entered {same as the rst} and the Enterfdd button is pressed. The LEDs should now show the result of the addition. The EnterfAdd button is pressed a third time and the LEDs are cleared showing DOUG. Ready to add two new binary numbers. Part 2. Add an LCD. 1. The top line of the LCD should display the addition in Decimal. E + 5 = 11 2. The bottom line of the LCD should display the addition in Hexadecimal. 6 + 5 = E
