| Symptom | Likely Cause | Fix | | :--- | :--- | :--- | | Sensor gets hot | JV1 set to 5V but sensor is 3.3V | Change JV1 to 3.3V immediately | | Nothing works | No power to shield | Check JV1 is not in middle position | | Upload fails | Device on D0/D1 | Unplug everything from pins 0 & 1 | | I2C scan finds nothing | Missing pull-up resistors | Add external 4.7k resistors | | Servo twitches | Insufficient current | Use external 6V supply on EXT_PWR | arduino sensor shield v5 0 manual

Even with a "Plug and Play" shield, issues arise. Here is the diagnostic manual. Enter the

| Problem | Likely Fix | |-------------------------------|-----------------------------------------------| | Shield doesn’t power on | Check Arduino USB/power. Re-seat shield. | | Servo twitches / resets Arduino | Use external power on EXT_PWR; open SJ1 jumper. | | I2C device not found | Check SDA/SCL wiring; add 4.7kΩ pullups if needed. | | Analog sensor reads 0 or 1023 | Verify GND connection; test sensor separately. | | Shield blocks USB port | Use a right-angle USB cable or USB extension. | This is your manual
