Conexiones y Estructura de Código Arduino

Thought for 2 mins 37 sec

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.
