Can you help me achieve the requirements using
Arduino? I have encountered some issues with these
requirements.
1. Functionality:**
The system must control 3 LEDS (Red, Green, and Blue) to produce at least 4 different lighting modes:
a. **Mode 1: All LEDs blink simultaneously at 1-second intervals.
b. Mode 2: LEDs blink in sequence (Red → Green → Blue) with a 500ms delay between each LED.
c. **Mode 3:** LEDs fade in and out smoothly (PWM control) in the order Red Green → Blue.
d. **Mode 4: Custom mode (e.g., random blinking or a pattern of your choice).
2. Constraints:**
-Use only one push button to cycle through the modes.
-The system must operate within a 5V power supply.
-The total current drawn by the LEDs must not exceed 100mA.
-Use resistors to limit the current through each LED appropriately.
3. Design Process:**
-Analysis: Calculate the required resistor values for each LED to ensure they operate within their
specified current limits.
Synthesis: Develop a circuit schematic and…

- 2. (35 points) Use you program to investigative properties of a four step linear pathway. Just extend the model given in question 1 to include an additional two species x2 and x3. You can assume simple irreversible mass-action kinetic on each reaction. I recommend you use the following values for the rate constants: 1 = 0.6; k2 = 1.8; k3 = 0.5; k40.04. This will enable you to more easily answer the following questions. You can also assume that the input is the source X and you can set its value to one. You may find that the plot of the phase change at x3 is broken at -180 degrees because it wraps around. To avoid this you can use the method: phase = np.unwrap(phase) to make sure the phase plot is continuous. [10] i) Compute and show the Bode plots for x1, x2 and x3 with respect to the input Xo.
