Pin Configuration

Component Documentation: 100 Ohm Resistor (Pack of 10)
Overview:
The 100 Ohm Resistor is a passive electronic component that opposes the flow of electric current. It is a fundamental component in electronic circuits, used to control voltage, current, and signal levels. This documentation provides a detailed explanation of the component's pins and how to connect them.
Pins:
The 100 Ohm Resistor has two pins, which are identical and interchangeable.
Pin 1: (Either end of the resistor)
+ Function: Input/Output
+ Description: This pin is one end of the resistor, where the voltage or current is applied.
Pin 2: (Either end of the resistor)
+ Function: Input/Output
+ Description: This pin is the other end of the resistor, where the voltage or current is measured or connected to another component.
Connecting the Pins:
Series Connection:
To connect the resistor in series with other components:
1. Connect one end of the resistor (Pin 1) to the positive terminal of a power source (e.g., a battery) or the output of another component.
2. Connect the other end of the resistor (Pin 2) to the input of another component or a device that requires a specific voltage or current.
Parallel Connection:
To connect the resistor in parallel with other components:
1. Connect both ends of the resistor (Pin 1 and Pin 2) across a power source or another component, ensuring that the voltage across the resistor is the same as the voltage across the other component.
2. The total resistance of the parallel circuit is the sum of the individual resistances.
Important Notes:
When connecting the resistor, ensure that the voltage and current ratings of the component are not exceeded, as this can cause damage or failure.
Use the correct wattage rating for your application to avoid overheating.
Always follow proper safety precautions when working with electricity.

Theory of Operation

A resistor is a passive electronic component that reduces the voltage or current in a circuit. It works by converting some of the energy from the circuit into heat. The resistance value, measured in Ohms (), determines the amount of energy that is dissipated.

Code Examples

Here are a few code examples that demonstrate how to use the 100 Ohm Resistor in various contexts:

Example 1: Voltage Divider Circuit with Arduino

In this example, we'll use the 100 Ohm Resistor to create a simple voltage divider circuit with an Arduino board. The voltage divider circuit will output 50% of the input voltage.

```c++
const int inputVoltage = 5;  // Input voltage from Arduino
const int outputVoltage = 0; // Output voltage to be measured

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

void loop() {
  int output = (inputVoltage  100) / (100 + 100); // Calculate output voltage
  Serial.print("Output Voltage: ");
  Serial.println(output);
  delay(1000);
}
```

Example 2: Current Limiting with Raspberry Pi

In this example, we'll use the 100 Ohm Resistor to limit the current to an LED connected to a Raspberry Pi's GPIO pin.

```python
import RPi.GPIO as GPIO

# Set up GPIO pin for output
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)

# Calculate current limit
current_limit = 5 / 100  # 5V power supply, 100 Ohm resistor

try:
    while True:
        # Turn on LED
        GPIO.output(17, GPIO.HIGH)
        print("LED is on")
        
        # Sleep for 1 second
        time.sleep(1)
        
        # Turn off LED
        GPIO.output(17, GPIO.LOW)
        print("LED is off")
        
        # Sleep for 1 second
        time.sleep(1)

except KeyboardInterrupt:
    GPIO.cleanup()
```

Example 3: Pull-Up Resistor with ESP32

In this example, we'll use the 100 Ohm Resistor as a pull-up resistor for a push button connected to an ESP32 board.

```c++
const int buttonPin = 15;  // Push button connected to GPIO 15
const int resistorPin = 16; // 100 Ohm resistor connected to GPIO 16

void setup() {
  Serial.begin(115200);
  pinMode(buttonPin, INPUT);
  pinMode(resistorPin, OUTPUT);
  digitalWrite(resistorPin, HIGH); // Pull-up resistor
}

void loop() {
  int buttonState = digitalRead(buttonPin);
  if (buttonState == LOW) {
    Serial.println("Button is pressed");
  } else {
    Serial.println("Button is not pressed");
  }
  delay(50);
}
```

These examples demonstrate the versatility of the 100 Ohm Resistor in various IoT projects. By understanding how to use resistors effectively, you can create a wide range of circuits and projects that interact with the physical world.
