LOGIC.LY CIRCUITS 1

Go to the free online demo for Logic.ly to create the following circuits.

For each circuit, you will be asked to do a screen capture and then to upload the image to Google Classroom.

TASK 1 – BASIC CIRCUITS

Before starting, take a minute to check out the interface.  You will find menus and tools at the top, components on the left and the main work space area on the right.

Create the following circuits. Test and analyze each of the power sources to understand how they work and what they do.

To Submit

A screen capture of your five circuits. Name your file task1.png.

TASK 2 – AND, OR & NOT CIRCUITS

Create the following circuits in Logic.ly. Create the truth table for each circuit.

To Submit

A screen capture of your three circuits. Name your file task2.png.

A screen capture or document with your three truth tables. Name your file task2b.png (or some other file extension.)

TASK 3 – NOR, NAND, XOR & XNOR CIRCUITS

a) Create a circuit like in Part 2 for a NOR gate.

b) Create a circuit like in Part 2 for a NAND gate.

c) Create a circuit like in Part 2 for an XOR gate.

d) Create a circuit like in Part 2 for an XNOR gate.

e) Associate each circuit above with its proper truth table below.

Truth table 1

A	B	Q
0	0	1
0	1	1
1	0	1
1	1	0

Truth table 2

A	B	Q
0	0	1
0	1	0
1	0	0
1	1	1

Truth table 3

A	B	Q
0	0	1
0	1	0
1	0	0
1	1	0

Truth table 4

A	B	Q
0	0	0
0	1	1
1	0	1
1	1	0

To Submit

A screen capture of your four circuits. Name your file task3.png.

Your answers to the association task (Example: a=table 3, b=table 4, c=table 2, d=table 1). Name this file task3b.png.

TASK 4 – THREE INPUTS

Notice the circuit below has three inputs A, B and C. Recreate it in logic.ly and then create the truth table for it. The truth table is started for you below.

Note that the truth table for a circuit needs to include all possible combinations of the inputs. Because there are 3 inputs in this circuit, our truth table will have 8 rows (instead of 4).

A	B	C	Q
0	0	0
0	0	1
0	1	0
0	1	1
1	0	0
1	0	1
1	1	0
1	1	1

To Submit

A screen capture of your circuit in a file starting with task4.

A screen capture or document of your truth table (will filename starting with task4b).
