1. Aim of the practical: To design the circuit below on tinkerCAD and verify the truth
table
2. Hardware Required:
i.
Wires
ii.
Logic gates (OR gate, NOT gate, AND gate)
iii.
Resistor
iv.
LED
v.
Slide switches
vi.
Power supply
vii.
Multimeter
3. Steps for experiment/ Theory:
 Open tinkerCAD
 Create a new workspace
 Input the breadboard
 Input the power supply
 Connect the positive to the positive part of breadboard and the negative
likewise
 Connect the breadboard positives and negatives to each other
 Input the multimeter
 Connect the positive and negative of the multimeter with the positive and
negative of the breadboard to check whether the breadboard is connected
properly by starting the simulation
 Input two slide switches
 Connect the common terminal to the ground
 Input two resistors and connect them to the positive on one side and the first
terminals of the slide switches respectfully
 Input the inverting (NOT) gate, the OR (7432 IC), the AND (7408 IC)
 Connect the inputs of each gate accordingly
 Input the LED and another resistor
 Connect one part of the resistor to the ground and the other to the cathode of
the LED
 Connect the final output of the circuit to the anode and start the simulation,
switching the switches on and off for different outputs.
4. Observations:
 When both switches are on the LED will light up
 When the first switch is on and the other off the LED will light up
 When the first switch is off and the second switch is on the LED does not light
 When both switches are off the LED does not light
