Arduino Sensor Shield V5 0 Manual 🆒

Cause: The RS‑485/TTL jumpers are in the wrong position.

Even with a "Plug and Play" shield, issues arise. Here is the diagnostic manual. arduino sensor shield v5 0 manual

The shield’s reset button physically presses the Arduino’s reset button. If you stack an LCD shield on top, the button might get stuck. Fix: Use extended stackable headers (female to male) to create a gap. Cause: The RS‑485/TTL jumpers are in the wrong position

Issue 2: I2C devices (like an OLED screen) are not being detected. Issue 2: I2C devices (like an OLED screen)

This is usually due to insufficient power. Install an external power supply to the SEL terminals and remove the SEL jumper. Analog sensors giving wrong readings: Ensure the pins are securely connected.

To use an I2C OLED display attached to the IIC header:

Cause: The SPI pins (D10–D13) might be shared with another device, or the chip select (CS) pin is not controlled correctly.
