Cayenne for Arduino Wait, Cayenne on Arduino? Yes, Cayenne on Arduino. The same Cayenne we've covered in the past can also be installed on, among many others, an Arduino board. Today we'll be covering the installation process. Hardware First, you'll need compatible hardware. The two basic things you need are the micro-controller itself and a network interface card. We used an Arduino Uno (rev. 3) and a SeeedStudio Ethernet Shield (v1.1). Cayenne is compatible with a wide range of other network cards and Arduino boards as well; check their site for full compatibility list. You also of course need a network to connect to, either wireless or wired, and a power source. If you plug into a computer, you can use the serial monitor to view debugging information. Software Installation Try watching this video: Go to Cayenne Log in or sign up Choose to add a new device Follow the prompts to select your board and network card(A SeeedStudio ethernet shield i...

Raspbian Jessie uses a different network manager than most other Linux systems and previous versions of Raspbian. Most users will have no use for a static IP, but it is necessary in some environments. There is a lot of confusion online, but this method has been tested to work with the newest edition of Raspbian as of August 8th, 2016. Also please note, depending on what you need a static IP for, it may be easier to go into your router(or other DHCP server) and specify an IP for your device there. First, open /etc/dhcpcd.conf with your favorite text editor(We'll use nano). Run the command: sudo nano /etc/dhcpcd.conf Add this to the end: interface eth0 static ip_address=192.168.1.7/24 static routers=192.168.1.1 static domain_name_servers=8.8.8.8 Use Ctrl+X to save and exit Replace ip_address with an IP of your choice, routers with the IP of your router or gateway, and domain_name_server with the IP of a DNS server. If you're on Wi-Fi, change "eth0" to...
