Arduino Sensor Shield V5 0 Manual

Check your ground connections. If you are using external power for the shield, ensure the ground of that external power supply is sharing a common ground with the Arduino (the shield handles this automatically if plugged in properly).

The Bluetooth/APC220 port shares the hardware serial pins ( D0 and D1 ) with the USB interface. You must unplug the Bluetooth module from the shield whenever you upload a new sketch from your computer, or the upload will fail.

Dedicated breakout headers for I2C, UART (Bluetooth), and SPI communication. arduino sensor shield v5 0 manual

Located along the top edge. Each pin features an adjacent VCC and Ground pin. Pins D0 and D1 double as the hardware TX/RX lines.

Setting this wrong will burn 3.3V sensors. The shield defaults to 5V from the factory. Check your ground connections

Keep this manual bookmarked. Remember the golden rules:

Near the blue terminal power block, you will find a 2-pin jumper labeled . You must unplug the Bluetooth module from the

Dedicated headers for I2C (SDA/SCL), SPI (for SD cards), and Serial/UART (for Bluetooth or APC220).

Connected to the Arduino’s common ground network. Usually labeled in black or blue. V (Voltage): Connected to the power rail ( by default). Usually labeled in red.

With this guide, you should be able to turn a pile of sensors into a working prototype in under ten minutes. Happy making.

Connects directly to the Arduino digital or analog I/O pin.
