Q14:Using the ADALP2000 analog parts kit / breadboard, construct the R-L voltage divider circuit using a 1k2 resistor and 10 mH inductor (code 103) as shown below. With the ADALM2000 SCOPY signal generator, adjust the input voltage (Vin) to 4.0 volts peak- to-peak (2.0 volts peak) at a frequency (f) of 60 kHz AC signal. Using the oscilloscope function of the SCOPY, display on your computer, both the input (Vin) and output (Vout) voltage waveforms on the same screen. Use the ADALM2000's 1+ and 1- wires to measure the voltage across Vin and the 2+ and 2-wires to measure the voltage across Vout. Note that once the circuit is connected to the signal source, the measured value of Vin on the oscilloscope will be slightly less that 4V p-p (2 V peak). This is due to the internal resistance of the SCOPY. For your calculations, use the measured value of Vin rather than 2.0V peak. Set Vin scaling for 500 mV/div and Vout scaling for 200 mV/div. Assume that the input voltage (Vin) is reference (Z = 0º). Remember that for a 60 kHz signal, the period, t = 1/f = 1/(60 x 10³) = 16.67 usec. Therefore, a 90° phase shift would result in a time difference (At) of 4.18 usec. Set the time-base scale on the SCOPY to 2.0 usec / div. Measure the time difference between the zero crossings of the two voltage sinewaves as the voltages are going positive in order to compute the phase angle difference (40) most accurately. Attach a picture of your circuit mounted on the breadboard as well as a screenshot from SCOPY showing both input and output voltage waveforms to this page. What At between the two waveforms and output voltage amplitude did you measure? Calculate the phase angle shift from At: Vout degrees (peak) (15 points) At= Is the output voltage (Vou) leading or lagging the input voltage (Vin)? Justify your answer by referencing the screenshot of the input/output waveforms. (2 points) Use hand calculations to verify your Vout measurement on a second piece of paper. What is the % error for the amplitude and phase shift measurements? (3 points) V₁ L + RVSee Answer

Q17:Supposed you are tasked to build a simple carbon monoxide sensor that functions in the following way: 1. Measure the CO2 sensor, which gives an analog output of 0 to 1.0V 2. A value of more than 0.5V represents a dangerous level of CO2 (0.0V means no CO2) 3. In the case of a dangerous condition, an alert must be given in the form of illuminating an external LED connected to any GPIO pin. 4. The sampling rate of the sensor must be 1kHz. 5. Use must use an ATTINY84 Microcontroller, which is also an 8-bit AVR processor similar (but different) to our 32u4 (datasheet attached). 1. Take a few minutes to review the datasheet to familiarize yourself with the available GPIO pins, available timers, and ADC setup. Review the address mappings in section 22 as well. For this part of the exam, you can not use known registers like PORTB etc. You must use unsigned char pointers to the correct addresses. 2. Write a function called void SetupTimer() that sets up any timer to function as a 1kHz timer (no PWM generation, no pins connected). The timer should reset every 1ms. Be sure to set up the appropriate registers in section 11.9 of the datasheet. 3. Write a function called void SetupLED() which sets up the selected GPIO pin (you can select any appropriate pin) for the LED alert. 4. Write a function called void SetupADC() which sets up the ADC to the appropriate MUX channel (you can choose any one you want). Set up the ADC to use a prescaler of 16, and use your timer overflow as an Auto Trigger Source for the ADC. See section 16.13.4 (Table 16.7) 5. Write the setup function that calls your functions described above. 6. Write the loop function that reads the ADC and performs the logic to illuminate the LED appropriately. Don't make the LED flicker if the ADC hovers around 0.5V! 7. Sketch the schematic that shows which pins you used and the interconnect diagram of the LED, ATTINY, and the CO2 sensor. 8. Now, using Platform IO, start a new project and use the board "Generic ATTINY84". Import the code you developed in 1. through 7., but now you can use the defined registers like PORTA etc. Submit the .cpp file with your code.See Answer
