ETron Circuit LabsLab 24 Audio GeneratorObjective:In this Lab you will build an Audio Generator circuit that will allow you to control the frequency of the pulses that produce the tone the speaker will put out.Step 1 – Take InventoryUsing the Parts Inventory as shown on the right under the “Here’s What You’ll Need” section, place each part needed for this experiment on its corresponding drawing. Observe the schematic symbol for each part. Make sure that you have all the parts ready before you begin Step 2.Step 2 – Build the CircuitUsing the Schematic Diagram and the picture of the completed lab, build the lab experiment with the electroniccomponents. Use the “Check Your Work Here” Box to verify that your wiring is correct, and then proceed to Step 3.Step 3 – Do ExperimentTheory:This Lab uses the 555 Timer IC as a source of a variable frequency of pulses which are sent to a46
