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.
