Welcome to my another Adder and Subtractor project. It's a topic of Digital And Logic Design by Morris Mano (fifth edition) with the help of this you'll know how its work in reality.
So let's get started.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Circuit Diagram
With the help of this diagram we build our Adder/Subtractor project.
Step 2: Materials
Some pieces of wire
Soldering wire and solder
Resistors: (330ohms x 13) and 1k
Ic's: lm7805, 74ls86 and 74ls38 with bases
Switches: spst x 9 and dpst x 1
Led's: red x 9 and yellow x 5
Step 3: Component Placing
Place the components according to diagram on vero board and soldering it.
Step 4: Soldering and Jumper Wires
Here it is the soldering and jumper wires.
Step 5: Finish
After its look like this.
Step 6: Examples
When you push the switch on left side then its work as a adder and on left side as a subtractor you can see on image. I uploaded a video on next step i'm sure it will clear your concept.
Step 7: Video
Thanks for watching.
I hope you guys like it.
