1k Ohm Resistor - (Pack of 10)
Overview
The 1k Ohm Resistor is a passive component that reduces the voltage or current in an electrical circuit. It is a fundamental component in electronic circuits and is commonly used to limit current, divide voltage, and provide impedance matching. This pack of 10 resistors is ideal for prototyping, testing, and production of IoT projects.
Specifications
Resistance: 1 k (1,000 Ohms)
 Power Rating: 1/4 Watt (0.25 W)
 Tolerance: 5%
 Operating Temperature: -55C to 155C
Pinout
Since this is a through-hole resistor, it does not have a specific pinout. The resistor has two leads, one for each end, which are connected to other components in the circuit.
Examples
Example 1: Limiting Current in an LED Circuit
In this example, we will use the 1k Ohm Resistor to limit the current in an LED circuit.
Circuit Diagram
```
  +5V --+-- [1k Ohm Resistor] --+--[LED]--+-- GND
```
Code Example (Arduino)
```c
const int ledPin = 13;  // Pin connected to LED
void setup() {
  pinMode(ledPin, OUTPUT);
}
void loop() {
  digitalWrite(ledPin, HIGH);  // Turn on the LED
  delay(1000);
  digitalWrite(ledPin, LOW);  // Turn off the LED
  delay(1000);
}
```
Explanation
In this example, the 1k Ohm Resistor is used to limit the current flowing through the LED. The resistor reduces the voltage from 5V to a safe level for the LED, preventing it from burning out.
Example 2: Voltage Divider Circuit
In this example, we will use the 1k Ohm Resistor to divide the voltage in a voltage divider circuit.

                     |
                     |
                     V
                   Output (2.5V)

GPIO.setmode(GPIO.BCM)
output_pin = 17
GPIO.setup(output_pin, GPIO.IN)

    voltage = GPIO.input(output_pin)
    print("Output voltage: {:.2f} V".format(voltage  2.5 / 255))
    time.sleep(1)
```
Explanation
In this example, two 1k Ohm Resistors are used to divide the input voltage (5V) in half, producing an output voltage of 2.5V. The Raspberry Pi reads the output voltage and prints it to the console.

```
  [Audio Source] --+--[1k Ohm Resistor]--+--[Audio Sink]
```
Code Example (MicroPython)
```python
import machine
audio_pin = machine.Pin(25)
audio_pin.init(machine.Pin.OUT)
while True:
    audio_pin.value(1)  # Output high signal
    time.sleep_ms(100)
    audio_pin.value(0)  # Output low signal
    time.sleep_ms(100)
```
Explanation
In this example, the 1k Ohm Resistor is used to attenuate the audio signal from the audio source before it reaches the audio sink. This reduces the signal amplitude and prevents damage to the audio sink.
