Usage Instructions
Connecting the Red Lamp in a Circuit
- Identify the Pins: The Red Lamp has two pins: the Anode (longer pin) and the Cathode (shorter pin).
- Connect to Power Source: Connect the Anode to the positive terminal of the power source and the Cathode to the negative terminal.
- Use a Current-Limiting Resistor: To prevent damage, use a resistor in series with the lamp. Calculate the resistor value using Ohm's Law: [ R = \frac{V_{supply} - V_{forward}}{I_{forward}} ] For example, with a 5V supply and a forward voltage of 2V: [ R = \frac{5V - 2V}{20mA} = 150\Omega ]
Example Circuit with Arduino UNO
To control the Red Lamp using an Arduino UNO, connect the Anode to a digital pin and the Cathode to the ground (GND) through a current-limiting resistor.

}
Important Considerations and Best Practices
- Current Limiting: Always use a current-limiting resistor to prevent excessive current flow.
- Polarity: Ensure correct polarity when connecting the lamp to avoid damage.
- Heat Dissipation: Avoid operating the lamp at maximum current for extended periods to prevent overheating.
Troubleshooting and FAQs
Common Issues
Lamp Does Not Light Up
- Solution: Check the power supply and ensure correct polarity. Verify the resistor value and connections.
Lamp Flickers
- Solution: Ensure stable power supply and secure connections. Check for loose wires or poor solder joints.
Lamp Burns Out Quickly
- Solution: Verify the current-limiting resistor value. Ensure the current does not exceed the rated forward current.
FAQs
Q: Can I use the Red Lamp with a 3.3V power supply?
- A: Yes, you can use a 3.3V power supply. Adjust the resistor value accordingly to limit the current.
Q: What is the maximum current the Red Lamp can handle?
- A: The maximum forward current is 20mA. Exceeding this can damage the lamp.
Q: Can I use the Red Lamp for AC applications?
