You will need to change the network settings in the program to correspond to your network. Make sure that the two share a common ground.Īfter wiring your sensor, your shield should be connected to a network with an Ethernet cable. The SPI pin numbers differ depending on which Arduino board you're using and are listed in the SPI reference page. this is the version of the code I am using. The way its stacked is arduino uno board, usb host shield then motor shield. Ive even tried powering it with an extra 4x AA batteries on my motor shield, but it still wont run. Running my arduino with one shield runs fine, but not with both shields stacked on top of my arduino. PS4 Bluetooth Library Started Bluetooth Dongle Initialized HCI Reset complete Write class of device Local Bluetooth Address: 00:11:22:98:76:54. Right now, Im using 8x AA batteries to power everything.

And the is what i get from the serial port. Your sensor's COPI (Controller Out Periheral In), MISO (Controller In Periheral Out), and SCK (SPI clock input) pins should then be connected to the SPI pins on your Arduino board/shield. I am using an Arduino UNO with he USB Host Shield Arduino. Connect the DRDY (Data Ready) pin on your sensor to digital pin 6 on your combo, and the CSB pin (Chip Select) to digital pin 7. Your Barometric Pressure sensor will be attached to pins 6,7, and the SPI pins of your Arduino / Ethernet shield combo, and powered via your device's 3.3 volt output. See the Barometric Pressure Sensor example for more on how the sensor works. After completing your circuit and uploading the example code below, simply navigate to your Ethernet shield's IP address, in a browser, to see this information. Using the Ethernet library, your device will be able to answer HTTP requests by responding with just enough HTML for a browser to display the temperature and barometric pressure values outputted by your sensor.

This example shows how to use SPI communications to read data from a SCP1000 Barometric Pressure sensor, and how to then post that data to the web by using your Arduino / Ethernet Shield combo as a simple web server.
