A botanist is interested in flower growth around the fields of their house. They find the flower growth, $ G $, is dependent on the number of minutes of shade the flowers receive every two hours, $ x $, and can be modeled by the function \[ G(x)=20-3 x \text {. } \] Draw the graph of the growth function by plotting its $ G $-intercept and another point.

Due: Wednesday, 8 May 2024, 12:30 PM Objective: Design and build a circuit using an Arduino Uno board and at least the other components shown in the image below. The circuit should display the temperature measured by the sensor on the LCD display in both Celsius and Fahrenheit. The color of the RGB LED and the position of the servo motor should change based on the temperature readings. Analog Temperature Sensor (NTC) RGB LED Servo UNO ARDUINO ANALOG I Display 16x2 Procedure: 1. Connect the ??? ?? ???? to the Arduino Uno board using the breadboard and jumper wires and other components as needed. 2. Write a program that does the following: Reads the temperature from the sensor. Displays the temperature on the LCD screen in both Celsius and Fahrenheit. Changes the color of the RGB LEDs and the position of the servo motor based on the temperature: If the temperature is less than or equal to 23°C, the RGB LED should display green and the servo motor should be at position 0. If the temperature is greater than 23°C and less than 30°C, the RGB LED should display yellow and the servo motor should be at position 45. • If the temperature is 30°C or greater, the RGB LED should display red and the servo motor should be at position 90. 3. Test the circuit. Expected Outcome: The circuit should accurately display the temperature in both Celsius and Fahrenheit on the LCD screen. The RGB LEDs should change color and the servo motor should change position based on the temperature readings. Upload to eclass: JPY Q Search

3. (40pt) Suppose an analog signal $g(t)$ is multiplied by a periodic signal $c(t)$ defined as $c(t) = h(t) * \delta_{T_s}(t)$, (17) where $h(t) = \text{rect}(\frac{t}{T})$ is a rectangular pulse with pulse duration $T$ and $\delta_{T_s}(t)$ is Dirac comb function with a period $T_s$. Assume that $f_sT \ll 1$. Let $s(t) = g(t)c(t)$. Find the expression of Fourier transform of $s(t)$ which does not have complex exponential function.
