What is the voltage drop across R₁ in terms of V_s?

Voltage Drop:  V_s

What is the total current through both resistors, R₁ and R₂?

Total Current: mA

What is the total equivalent resistance connected to the voltage source V_s?

Total Equivalent Resistance:  Ω

Given the circuit diagram:

Select the image that correctly identifies all nodes in the circuit.

Based on your answers in Q1b, Explain why the observed values match, or do not match your expectations (the theoretical value).

Circuit

Build the circuit on a breadboard.

1. Calculate the theoretical V_out and fill out the first field below.
2. Then, use a multimeter, measure V_out and fill out the second field below.

Note: You will need to connect the positive multimeter probe to V_out, and the negative multimeter probe to GND_ref (the ground rail) on the circuit.

Breadboard Diagram

Theoretical V_out: V

Measured V_out: V

Given the circuit diagram:

Select the image that correctly identifies all nodes in the circuit.

What is the minimum and maximum distance that an ultrasonic sensor HC-SR04 is able to sense an object reliably? 

Note: You will need to do some research for this task.

Minimum Distance:  cm

Maximum Distance:  cm

Draw a circuit diagram that implements the ultrasonic sensor with the Arduino. 

You should upload/attach a photo/screenshot of the circuit diagram as a pdf file.

It is recommended that you complete the circuit diagram using draw.io.

Note: Don't forget to meet circuit diagram standards!

Given the segment layout of a single 7-segment display digit below,

Identify the pin-out mapping for each of the pins on the 4 digit 7-segment display in your kit.
