------------------### Example 1: Voltage Divider Circuit with an ArduinoIn this example, we'll use two 330 Ohm resistors to create a voltage divider circuit that reduces a 5V input voltage to 3.3V, suitable for an IoT sensor.```c++
const int sensorInput = A0; // Sensor input pin
const int sensorOutput = 3; // Sensor output pinvoid setup() {
pinMode(sensorInput, INPUT);
pinMode(sensorOutput, OUTPUT);
}void loop() {
// Create a voltage divider circuit using two 330 Ohm resistors
int sensorValue = analogRead(sensorInput);
float voltage = (sensorValue 5.0) / 1023.0;
float outputVoltage = voltage (330.0 / (330.0 + 330.0));
analogWrite(sensorOutput, outputVoltage);

import RPi.GPIO as GPIO# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Define LED pin
LED_PIN = 17# Set up LED pin as output
GPIO.setup(LED_PIN, GPIO.OUT)try:
# Calculate current limiting resistor value for 20mA current
resistorValue = 330 # Ohms
voltageSupply = 5 # Volts
currentLimit = 0.02 # Amps
ledVoltage = 2 # Voltsresistance = (voltageSupply - ledVoltage) / currentLimit
print("Calculated resistor value: {:.2f} Ohms".format(resistance))# Connect the resistor in series with the LED
GPIO.output(LED_PIN, GPIO.HIGH) # Turn on LEDwhile True:
# Keep the LED on
passexcept KeyboardInterrupt:
GPIO.cleanup()
```### Example 3: Signal Attenuation in a Wireless Communication CircuitIn this example, we'll use a 330 Ohm resistor to attenuate a wireless communication signal to prevent signal overload.```c
#include <WiFi.h>const char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";WiFiClient espClient;void setup() {
Serial.begin(115200);
WiFi.begin(ssid, password);// Wait for Wi-Fi connection
while(WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}Serial.println("Connected to WiFi");
Serial.println("Initializing wireless communication...");// Create a signal attenuation circuit using a 330 Ohm resistor
const int signalPin = 2; // Signal input pin
const int attenuatedPin = 4; // Attenuated signal output pinpinMode(signalPin, INPUT);
pinMode(attenuatedPin, OUTPUT);// Calculate attenuation factor
float attenuationFactor = 20.0 log10(330.0 / (330.0 + 330.0));// Attenuate the signal
float signalValue = analogRead(signalPin);
float attenuatedValue = signalValue attenuationFactor;
analogWrite(attenuatedPin, attenuatedValue);
}void loop() {
// Perform wireless communication using the attenuated signal
espClient.setServer("http://example.com", 80);
espClient.println("GET / HTTP/1.1");
espClient.println("Host: example.com");
espClient.println("Connection: close");
espClient.println();int bytesRead;
char response[512];while((bytesRead = espClient.available()) > 0) {
bytesRead = espClient.readBytes(response, bytesRead);
Serial.println(response);
}
