Nodo / ConexiónDescripciónComponentes involucrados
Alimentación principalConecta el terminal positivo de V1 (Fuente DC) a:- La entrada de 7805 (U4), para obtener 5V regulados.- El terminal VS del L298N (U3), que alimenta los motores.V1, 7805 (U4), L298N (U3)
Tierra (GND)Conecta el terminal negativo de V1 y todos los pines de GND de los demás componentes al punto de referencia común usando el componente Ground.V1, 7805 (U4), L298N (U3), ESP32-WROOM-32 (U1), CNY70 (U2) y el segundo sensor (a duplicar)
Regulación de 5VLa salida de 5V de 7805 (U4) se usa para:- Alimentar la lógica (VSS) del L298N (U3).- Alimentar los LED de los sensores (lado emisor de infrarrojos del CNY70).7805 (U4), L298N (U3), CNY70 (U2) y duplicado para el segundo sensor
Control de motoresConecta las salidas de control del L298N (U3):- Conecta ENA, IN1 e IN2 a salidas digitales de ESP32-WROOM-32 (U1) para controlar el primer motor.- Conecta ENB, IN3 e IN4 a otras salidas digitales de ESP32-WROOM-32 (U1) para el segundo motor.L298N (U3), ESP32-WROOM-32 (U1)
MotoresConecta los motores a las salidas del L298N:- Conecta OUT1 y OUT2 al primer DC Motor (M1).- Conecta OUT3 y OUT4 al segundo DC Motor (M2).L298N (U3), DC Motor (M1 y M2)
Conexiones de sensoresPara cada sensor CNY70:- Lado LED (emisor IR): - Conecta el pin A a la salida de 5V (desde 7805 U4) a través de un resistor limitador (recomiendo agregar uno si no está presente aún). - Conecta el pin K a GND.- Lado fototransistor: - Conecta el pin C a una resistencia de pull-up (por ejemplo, 4.7kΩ o 10kΩ) a 5V y también a un pin ADC del ESP32-WROOM-32 (puedes usar IO34 para el primer sensor y IO35 para el segundo sensor). - Conecta el pin E a GND.Primer sensor: CNY70 (U2).Segundo sensor: Se debe duplicar el componente CNY70 con un designador diferente (por ejemplo, U5).7805 (U4), ESP32-WROOM-32 (U1)
Notas adicionales:
  • Asegúrate de agregar los componentes pasivos necesarios, como resistencias limitadoras para los LED de los sensores y resistencias de pull-up para los pines analógicos.
  • Todas las conexiones a tierra deben unirse mediante el componente Ground para mantener una referencia común.
  • La conexión de los pines de control del L298N al ESP32-WROOM-32 permitirá que el microcontrolador dirija la velocidad y dirección de los motores según la lectura de los sensores.
