Creating a connection map.

Perfecto. Con Arduino Uno, una fotoresistencia (LDR), un par IR (emisor y receptor) y un buzzer, así conectas todo según tu sketch (pines ya definidos en el código):

Componentes

Controladora: Arduino-UNO-R3
LDR: PDV-P8103
LED IR emisor: IR333-A
Receptor IR (fototransistor): NTE3034A Phototransistor
Buzzer pasivo: MLT-8530
Resistencias: 220Ω 0603, 10kΩ 0603
Desacople recomendado: 100nF 0603

Conexiones a Arduino (mismas etiquetas del sketch)

IR_LED = D3 (emisor IR):
- D3 -> 220Ω 0603 -> ánodo de IR333-A
- cátodo del IR -> GND
IR_SENSOR = A0 (receptor IR con fototransistor):
- 5V -> colector del NTE3034A Phototransistor
- emisor -> nodo de lectura A0
- A0 -> 10kΩ 0603 -> GND
- Nota: con más IR, sube la lectura en A0. Puedes ajustar la resistencia (4.7k–47k) para sensibilidad.
LDR_SENSOR = A1 (divisor con LDR):
- 5V -> PDV-P8103 -> nodo A1
- A1 -> 10kΩ 0603 -> GND
- Nota: así A1 sube con más luz. Ajusta a 22k/47k si necesitas más rango.
BUZZER_PIN = D2 (buzzer pasivo):
- D2 -> (+) de MLT-8530
- (-) del buzzer -> GND
- Si tu buzzer es activo, sonará al nivel alto; para tonos del sketch usa uno pasivo.

Alimentación y buenas prácticas

Une todas las GND en común.
Coloca un 100nF 0603 entre 5V y GND cerca de los sensores para reducir ruido.
Los umbrales del código (IR<=16, LDR<750) dependen del ambiente y resistencias; ajusta si hace falta.

¿También vas a usar la pantalla OLED, botones y joystick del sketch, o por ahora solo LDR + IR (emisor/receptor) + buzzer? Si es solo eso, te indico qué líneas del código comentar para que compile y funcione sin los demás.

Generic Capacitor
A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
