• 1 x LED rojo
• 1 x LED amarillo
• 1 x LED verde
• 3 x resistencias de 220Ω (para limitar la corriente hacia los LEDs)
• Arduino Uno

1. LED Rojo: conecta el ánodo (lado largo) a través de una resistencia de 220Ω al pin digital D2_INT0. Conecta el cátodo (lado corto) a uno de los pines GND.
   • Connect D2_INT0 to R1:1 (ánode LED rojo), y R1:2 to GND.
2. LED Amarillo: conecta el ánodo a través de una resistencia de 220Ω al pin digital D3_INT1. Conecta el cátodo a uno de los pines GND.
   • Connect D3_INT1 to R2:1 (ánodo LED amarillo), y R2:2 to GND.
3. LED Verde: conecta el ánodo a través de una resistencia de 220Ω al pin digital D4. Conecta el cátodo a uno de los pines GND.
   • Connect D4 to R3:1 (ánodo LED verde), y R3:2 to GND.

1. In your Flux project, access the Flux library and search for an IR sensor. Find a suitable one for your application, considering its features and compatibility with your Arduino Uno.
2. Once you have chosen an IR sensor part, you will need to place it into your schematic. To do so, select the part in the library and then click on the desired location within your schematic.
3. After placing the IR sensor in the schematic, you will need to design the IR sensor interface. Typically, an IR sensor will interface with the Arduino through a digital or analog pin, which corresponds to a terminal in the schematic. Look up the specific requirements of your chosen IR sensor.
4. To physically connect the IR sensor's output pin (often labeled as OUT) to the Arduino, you can wire it to a specific Arduino digital input terminal in your schematic. For example, you might wire it to the D2_INT0 terminal. You could specify this connection as follows:

Wire D2_INT0 (pin) of Arduino_Uno_Shield (designator XA1) to OUT (pin) of IR_Sensor (designator: XX)

5. Be sure to also connect the power (VCC/5V and GND) pins of the IR sensor to the respective terminals on the Arduino (like SPI_5V for power and GND for ground, based on your project description).
6. Once you have connected the sensor in the schematic, you will also need to update the PCB layout to reflect these changes.
