threshold según tu sensor y las necesidades de tu aplicación. Recuerda que cada sensor puede tener diferentes características y valores de salida, así que debes calibrar tu sistema según las lecturas que observes en tu entorno de prueba.Table
| Step | Objective | Procedure | Expected Outcome |
|---|---|---|---|
| 1 | Verify power supply | Apply a stable 5V supply to pin 5 (+5V_1) and a ground connection to pin 6 (GND1). | The onboard power LED should light up, indicating the board is powered. |
| 2 | Test RESET functionality | Briefly connect pin 3 (RESET) to ground. | The board should reset, indicated by a quick blink of the LED on pin 13 (assuming standard Arduino bootloader behavior). |
| 3 | Test digital I/O | Connect an LED and a resistor in series from a digital IO pin (e.g., pin 69 (0)) to ground, and upload a sketch that toggles this pin HIGH and LOW. | The LED should blink in the pattern defined by the sketch, confirming digital I/O functionality. |
| 4 | Verify analog input | Connect a variable voltage source (e.g., a potentiometer connected to +5V and GND) to an analog input, such as pin 9 (AD0), and upload a sketch that reads this value and sends it over the serial port to a computer. | The voltage readings sent to the computer should correspond with the adjustments made to the potentiometer, confirming the analog input functionality. |
| 5 | Test serial communication (USART) | Connect the Arduino's TX (pin 70 (1)) to another device's RX and vice versa. Upload a sketch that sends a message from the Arduino to the other device. | The connected device should receive the message accurately, confirming Serial TX/RX functionality. |
| 6 | Verify I2C functionality | Connect I2C sensors or other I2C peripheral to SDA (pin 85) and SCL (pin 86), along with appropriate power and grounding. Upload a sketch that communicates with the I2C device. | The Arduino should successfully communicate with the I2C device, confirming I2C functionality. |
| 7 | Test SPI communication | Connect an SPI device to pins 51 (SPI MOSI), 50 (SPI MISO), 52 (SPI SCK), and any digital I/O for SS (e.g., pin 53), and upload a sketch to communicate with the SPI device. | Successful communication with the SPI device, indicating SPI functionality. |
| 8 | Verify external power capability | Disconnect any USB power and connect an external power source to pin 8 (VIN) with an appropriate voltage (7-12V recommended). | The board should power up just like it did with 5V USB power, confirming external power functionality. |
| 9 | Test additional digital and analog pins | Repeat steps 3 and 4 for additional digital and analog pins, respectively, to ensure all are functional. | All tested I/O pins should function as expected, demonstrating their integrity. |
| 10 | Verify onboard LED | Upload a sketch that toggles pin 13 (assumed onboard LED connected to digital pin 13) HIGH and LOW. | The onboard LED should flash in accordance with the sketch, confirming its functionality. |

(Nota: el uso de +3V3 o RESET como ejemplos no es típico para controlar motores; normalmente, se usarían pines digitales programables, pero estoy ajustándome a tu lista de componentes y toma en cuenta que necesitas utilizar pines digitales PWM para un control más adecuado).Cpp
