How to Use

Resistors are passive components that can be used in a variety of applications. Here are a few code examples that demonstrate how to use this component in different contexts:

### Example 1: Basic Voltage Divider Circuit with Arduino

In this example, we'll use the 47k ohm resistor to create a simple voltage divider circuit to measure the voltage across a sensor.

Circuit Diagram

Connect the 47k ohm resistor (R1) between the positive leg of the sensor (e.g., a photodiode) and the positive rail (VCC) of the Arduino board.
 Connect a 10k ohm resistor (R2) between the negative leg of the sensor and the analog input pin (A0) of the Arduino board.
 Connect the sensor to a power source (e.g., 5V).

Arduino Code
```c++
const int sensorPin = A0;  // Analog input pin
int sensorValue = 0;        // Variable to store sensor reading

void setup() {
  Serial.begin(9600);
}

void loop() {
  sensorValue = analogRead(sensorPin);
  float voltage = sensorValue  (5.0 / 1023.0);
  Serial.print("Sensor voltage: ");
  Serial.println(voltage, 2);
  delay(1000);
}
```
### Example 2: Signal Attenuation in a Wireless Sensor Node with ESP32

In this example, we'll use the 47k ohm resistor to attenuate the signal from a wireless sensor node to prevent damage to the ESP32 microcontroller.

Circuit Diagram

Connect the 47k ohm resistor (R1) between the output pin of the wireless sensor (e.g., a temperature sensor) and the input pin of the ESP32 board.
 Connect a 10uF capacitor (C1) between the input pin of the ESP32 board and ground to filter out noise.

ESP32 Code (MicroPython)
```python
import machine
import utime

# Define the pin connections
 sensor_pin = machine.Pin(32, machine.Pin.IN)
 esp32_pin = machine.Pin(15, machine.Pin.IN)

while True:
    # Read the sensor value
    sensor_value = sensor_pin.value()

# Attenuate the signal using the 47k ohm resistor
    attenuated_value = sensor_value  (5.0 / 3.3)  # assume 3.3V input

# Print the attenuated value
    print("Attenuated sensor value: ", attenuated_value)
    utime.sleep(1)
```
These examples demonstrate how to use the 47k ohm resistor in simple circuits for voltage division and signal attenuation. The resistor can be used in various other applications, such as:

Current limiting in LED circuits
