220 Ohm Resistor (Pack of 10)

Description

The 220 Ohm Resistor is a passive electronic component that opposes the flow of electrical current. It is a type of fixed resistor, meaning its resistance value remains constant and is not adjustable. This component is commonly used in a wide range of electronic circuits and projects, including IoT applications, robotics, and DIY electronics.

Functionality

The primary function of the 220 Ohm Resistor is to reduce the voltage or current in a circuit, thereby controlling the amount of energy flowing through it. This is achieved by converting some of the energy into heat, which is then dissipated into the environment. Resistors are essential in electronic circuits, as they help to

Limit the current flowing through a component to prevent overheating or damage

Divide voltage levels between different parts of a circuit

Impede the flow of AC (alternating current) signals

Provide a fixed reference point for voltage or current measurements

Additional Information

The 220 Ohm Resistor is a popular value in electronic circuits and is often used in conjunction with other components to create voltage dividers, signal attenuators, and current limiters.

The component is RoHS (Restriction of Hazardous Substances) compliant, ensuring it meets environmental standards for electronic components.

The through-hole design makes it easy to mount the resistor onto a PCB (Printed Circuit Board) or breadboard, with sufficient clearance for soldering and wire management.

Tips and Precautions

When handling resistors, ensure they are not exposed to excessive heat, moisture, or physical stress, which can affect their performance and lifespan.

Use a resistor with a suitable power rating for your application to prevent overheating and failure.

Always verify the resistor's value and tolerance before using it in a circuit to ensure accurate results.

By incorporating the 220 Ohm Resistor into your IoT project or electronic circuit, you can take advantage of its reliable performance and versatility to achieve precise control over voltage and current flows.

  • Terminal 1: One end of the resistor, marked with a color code (more on this below)
  • Function: Connects to a voltage source, a sensor, or another component in the circuit
  • Signal: Carries the input voltage or current
  • Pin 2:
  • Terminal 2: The other end of the resistor, also marked with a color code
  • Function: Connects to a load, ground, or another component in the circuit
  • Signal: Carries the output voltage or current, which is reduced by the resistor's opposition
  • Color Code
  • The 220 Ohm Resistor has a color code to indicate its resistance value. The color code is as follows:
  • Red: 2 (first significant digit)
  • Black: 2 (second significant digit)
  • Brown: 0 (multiplier)
  • Gold: 5% (tolerance)
  • This color code represents a resistance value of 220 Ohms, with a tolerance of 5%.
  • Connecting the Pins
  • To connect the 220 Ohm Resistor correctly, follow these steps:
  • 1. Identify the terminals: Determine which end is Terminal 1 and which is Terminal 2. The terminals are identical, so it doesn't matter which one is which.
  • 2. Determine the circuit configuration: Decide how you want to connect the resistor in your circuit. Common configurations include:
  • Voltage divider: Connect Terminal 1 to a voltage source and Terminal 2 to a load or another resistor.
  • Current limiter: Connect Terminal 1 to a power source and Terminal 2 to a load or a sensor.
  • 3. Connect the wires: Use suitable wires or connectors to connect the resistor to the desired components in your circuit.
  • 4. Verify the connections: Double-check your connections to ensure the resistor is correctly installed in the circuit.
  • Important Notes
  • Always handle the resistor by the body, not the pins, to prevent damage or electrostatic discharge.
  • Use the correct voltage and current ratings for the resistor to prevent overheating or damage.
  • Verify the resistance value and tolerance before using the resistor in your circuit.
  • By following these guidelines, you can correctly connect the 220 Ohm Resistor in your IoT project and ensure reliable operation.

Code Examples:
### Example 1: LED Circuit with Raspberry Pi
In this example, we'll use the 220 Ohm Resistor to limit the current flowing through an LED connected to a Raspberry Pi's GPIO pin.
Circuit Diagram:
Raspberry Pi (GPIO pin)
 220 Ohm Resistor (R1)
 LED (D1)
Raspberry Pi Code (Python):
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)  # Set GPIO 17 as output
while True:
    GPIO.output(17, GPIO.HIGH)  # Turn on LED
    time.sleep(1)
    GPIO.output(17, GPIO.LOW)  # Turn off LED
    time.sleep(1)
```
Explanation: The 220 Ohm Resistor (R1) is used to limit the current flowing through the LED (D1) to prevent it from burning out. The resistor is connected in series with the LED and the Raspberry Pi's GPIO pin 17. The Python code toggles the GPIO pin high and low to turn the LED on and off.
### Example 2: Voltage Divider with Arduino
In this example, we'll use the 220 Ohm Resistor as part of a voltage divider circuit to reduce a 5V input voltage to 2.5V.

 Arduino Board (Analog Input)
Arduino Code:
```cpp
const int sensorPin = A0;  // Analog input pin
int sensorValue = 0;
void setup() {
  Serial.begin(9600);
}
void loop() {
  sensorValue = analogRead(sensorPin);
  float voltage = sensorValue  (5.0 / 1023.0);
  Serial.print("Voltage: ");
  Serial.print(voltage);
  Serial.println(" V");
  delay(1000);
}
```
Explanation: The two 220 Ohm Resistors (R1 and R2) are connected in series to form a voltage divider, reducing the 5V input voltage to 2.5V. The Arduino Board reads the divided voltage through its Analog Input pin (A0). The Arduino code converts the analog reading to a voltage value and prints it to the serial monitor.
These examples demonstrate the usage of the 220 Ohm Resistor in different contexts, showcasing its versatility and importance in various IoT projects.
