ETron Circuit LabsLab 33 Electronic OrganObjective:In this Lab you will build an Electronic Organ that will allow you create the Do-Re-Mi-Fa-So-La-Ti-Do sounds by moving the probes across different resistors.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 electronic components. Use the “Check Your Work Here” Box to verify that your wiring is correct, and then proceed to Step 3.Step 3 – Do Experiment Theory:In this Lab you will use the 555 Timer IC as an astable multivibrator. As you vary the resistance value connected to Pins 2 and 6, the amount of time to charge C1 changes. The lower the value of the resistor, the faster that C1 charges. This change inTone Probes64
