Solved Step By Step with Explanation –Button-Controlled LED, Buzzer & RGB

import time

GPIO.setmode(GPIO.BOARD)

while True:

button_state = GPIO.input(button_pin)

```

Explanation: This program uses the RPi.GPIO library to control the LED and read the button state. When the button is pressed, it toggles the state of the LED.

GPIO.setmode(GPIO.BOARD)

button_pin = 12

GPIO.setup(red_pin, GPIO.OUT)

GPIO.setup(green_pin, GPIO.OUT)

GPIO.output(blue_pin, b)

while True:

set_rgb_color(0, 1, 0) # Green

time.sleep(0.5)

3. Push Button + Active Buzzer:

```python

buzzer_pin = 11

GPIO.setup(button_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

buzzer_state = not GPIO.input(buzzer_pin)

GPIO.output(buzzer_pin, buzzer_state)

```python

import RPi.GPIO as GPIO

GPIO.setup(button_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

GPIO.setup(buzzer_pin, GPIO.OUT)

if button_state == GPIO.LOW:

buzzer.ChangeFrequency(880)

Explanation: This program plays two different frequencies on the passive buzzer when the button is pressed.

5. Push Button + RGB + Active Buzzer:

button_pin = 12

red_pin = 11

GPIO.setup(red_pin, GPIO.OUT)

GPIO.setup(green_pin, GPIO.OUT)

GPIO.output(green_pin, g)

GPIO.output(blue_pin, b)

button_state = GPIO.input(button_pin)

if button_state == GPIO.LOW:

set_rgb_color(0, 1, 0) # Green

time.sleep(0.5)

Explanation: This program combines the functionalities of the previous scenarios. It toggles the buzzer and cycles through RGB colors when the button is pressed.

Remember that these programs assume a basic setup and use the RPi.GPIO library for controlling GPIO pins on a Raspberry Pi. Make sure you have the necessary components connected correctly and consider adapting the code to your specific hardware setup if needed.
