In this lab, you will build your adder circuit using AND, OR, and NOT gates as shown in Figure 1. You need three TTL ICs for this circuit. You may need to reference to lab 1 for other chip diagrams. Make sure all ICs are powered, and take advantage of color coded wire for better tracing your circuit. Try to wire your components in a neat way.
