Understanding Common Anode Bi-Color LEDs
These LEDs are Common Anode (CA) type. This means the longest lead is the common positive (+) terminal. The two shorter leads are the cathodes (-) for the red and green LEDs respectively.
- Longest Lead: Common Anode (+)
- Shorter Lead 1: Cathode (-) for Red LED
- Shorter Lead 2: Cathode (-) for Green LED
To illuminate the red LED, connect the common anode to a positive voltage source (e.g., +5V) and the red cathode to ground, typically through a current-limiting resistor. Similarly, for the green LED, connect the common anode to positive and the green cathode to ground via a resistor.

Configuració i connexió
Proper setup is crucial for the longevity and performance of your LEDs. Always use a current-limiting resistor in series with each LED to prevent damage from excessive current.
Calculating Resistor Value:
Use Ohm's Law: R = (Vs - Vf) / I
- R: Resistor value in Ohms (Ω)
- Vs: Subministrament voltage (e.g., 5V from Arduino)
- Vf: Endavant voltage of the LED (Red: 2V-2.2V, Green: 3V-3.2V)
- I: Desired forward current (typically 20mA or 0.02A for these LEDs)
Example for Red LED (Vs=5V, Vf=2.1V, I=0.02A): R = (5V - 2.1V) / 0.02A = 2.9V / 0.02A = 145 Ω. A common resistor value like 150 Ω or 220 Ω would be suitable.
Example for Green LED (Vs=5V, Vf=3.1V, I=0.02A): R = (5V - 3.1V) / 0.02A = 1.9V / 0.02A = 95 Ω. A common resistor value like 100 Ω or 120 Ω would be suitable.
Passos de connexió:
- Identify the common anode (longest lead) and the two cathode leads.
- Connect the common anode lead to your positive voltage subministrament.
- Connect a calculated current-limiting resistor in series with each of the two cathode leads.
- Connect the other end of each resistor to the control pin (e.g., microcontroller output) or directly to ground if always on.
- Assegureu-vos que totes les connexions estiguin segures i correctes abans d'aplicar l'alimentació.

Operating the LEDs
These bi-color LEDs allow for individual control of red and green light, or a combination to create a mixed color (e.g., orange/yellow depending on intensity).
- Llum vermella: Aplicar el vol adequattage to the common anode and connect the red cathode (shorter lead) to ground via its resistor.
- Llum verda: Aplicar el vol adequattage to the common anode and connect the green cathode (shorter lead) to ground via its resistor.
- Mixed Color: Aplicar el vol adequattage to the common anode and connect both red and green cathodes to ground via their respective resistors. The resulting color will be a blend of red and green.

Manteniment
These LEDs are robust electronic components and require minimal maintenance.
- Emmagatzematge: Store LEDs in a dry, cool environment, preferably in their original anti-static packaging, to prevent damage from moisture or static discharge.
- Manipulació: Avoid bending the leads excessively or repeatedly, as this can cause them to break. Handle by the body of the LED whenever possible.
- Neteja: If necessary, gently wipe the LED lens with a soft, dry cloth. Avoid using harsh chemicals.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El LED no s'encén. | Incorrect polarity, insufficient voltage, no current-limiting resistor, faulty connection, or damaged LED. | Verify common anode and cathode connections. Check power supply voltage. Ensure a resistor is in series. Inspect solder joints/connections. Test with a known good LED. |
| LED is too dim or too bright. | Incorrect resistor value. | Recalculate and replace the current-limiting resistor with the appropriate value for desired brightness. |
| Only one color lights up. | Connection issue with one of the cathode leads or its resistor. | Check the connection and resistor for the non-lighting color. Ensure the correct cathode is being driven. |
