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…

- not use aiarrow_forward2. (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.

The zombie alarm you built goes off as they open the door. You jolt awake to see an alpha-zombie charging through the door. The alphas are zombies that turned all of the zombies in its army. If you can take down this one zombie, all the others pouring into the room should fall as well. Luckily, your group was prepared for this eventuality. Another member of your team has constructed the zombie shocker circuit shown in Figure 5, using some batteries for the voltage source, some rusty metal for the resistors and a coil of wire for the inductor. The switch is just you pulling apart two wires to open the circuit (while holding them by their insulated sheaths). 1. Construct the circuit shown in Figure 15 in the Circuit JS simulator. 2.
