4. Setup and Connection
Proper connection is crucial for the functionality and longevity of your LEDs. Incorrect wiring can damage the LED or your power source.
4.1 Identifying Polarity
- Anode (+): The longer lead of the LED. This connects to the positive terminal of your power supply.
- Cathode (-): The shorter lead of the LED. This connects to the negative terminal (ground) of your power supply.
- Additionally, the cathode side of the LED usually has a flat edge on the plastic casing.

4.2 Current Limiting Resistor
LEDs require a current-limiting resistor in series to prevent damage from excessive current. Connecting an LED directly to a voltage source without a resistor will likely burn out the LED instantly.
- Calculating Resistor Value: Use Ohm's Law: R = (Vs - Vf) / I, where:
- R: Resistor value in Ohms.
- Vs: Supply voltage (e.g., 5V, 9V, 12V).
- Vf: Forward voltage of the LED (refer to Table 3.1 or Figure 3.1 for specific LED color values).
- I: Desired forward current (typically 20mA or 0.02A for these LEDs).
- Example: For a Red LED (Vf ≈ 2.0V) with a 5V supply and desired 20mA current: R = (5V - 2.0V) / 0.02A = 3V / 0.02A = 150 Ohms.
4.3 Basic Connection Steps
- Identify the anode (longer lead) and cathode (shorter lead) of the LED.
- Connect one end of the calculated current-limiting resistor to the positive terminal of your power supply.
- Connect the other end of the resistor to the anode (longer lead) of the LED.
- Connect the cathode (shorter lead) of the LED to the negative terminal (ground) of your power supply.
- Ensure all connections are secure before applying power.
5. Operating Instructions
Once properly connected with a current-limiting resistor, apply power to your circuit. The LED should illuminate. If it does not, refer to the Troubleshooting section.
- Brightness Control: The brightness of the LED is primarily controlled by the current flowing through it. A higher current (within the LED's maximum rating) will result in greater brightness. This can be adjusted by changing the value of the current-limiting resistor.
- Pulse Width Modulation (PWM): For advanced brightness control and color mixing in RGB applications, Pulse Width Modulation (PWM) can be used with microcontrollers like Arduino or Raspberry Pi.
6. Care and Maintenance
These LEDs are robust electronic components, but proper handling and storage will ensure their longevity.
- Handling: Avoid bending the leads excessively close to the LED body, as this can damage the internal structure. Handle by the leads or the plastic body, not the lens.
- Storage: Store unused LEDs in their original packaging or in an anti-static container in a cool, dry place to prevent damage from moisture or static electricity.
- Cleaning: If necessary, gently wipe the LED lens with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
7. Troubleshooting
If your LED is not functioning as expected, consider the following common issues:
- LED Not Lighting Up:
- Check Polarity: Ensure the anode (longer lead) is connected to the positive supply and the cathode (shorter lead) to ground.
- Verify Resistor: Confirm that a current-limiting resistor is in series with the LED and its value is correctly calculated for your supply voltage and LED forward voltage.
- Power Supply: Check if your power supply is providing the correct voltage and current.
- Damaged LED: The LED might be damaged if it was connected without a resistor or to an excessive voltage. Try another LED from the kit.
- LED is Dim:
- Resistor Value: The resistor value might be too high, limiting the current excessively. Recalculate or try a slightly lower resistance (ensure current does not exceed 20mA).
- Power Supply: The supply voltage might be too low.
- LED is Too Bright / Burns Out Quickly:
- Resistor Value: The resistor value is too low or missing. Immediately disconnect power and install a correctly calculated current-limiting resistor.
- Excessive Voltage: The supply voltage might be too high for the LED even with a resistor.
