Cloud computing is the process by which information can be sent back and forth over the Internet using a variety of different "pay-as-you-go" cloud services. The BB-400 is compatible with a number of cloud services, and this FAQ will explore one of these options: FRED.
PWM (Pulse Width Modulation) is a way to control analog devices using digital output. PWM “fakes” an analog-like result by applying power in pulses, or short bursts of the regulated voltage:
This FAQ gives examples with different methods for a user to use push notifications. Push notifications are simple notifications which a user can setup for when a specific event has happened. An example of this would be, if one of the BB-400 inputs signal high, immediately send a notification via email.

This FAQ explains how to use different nodes inside Node-RED, being used to show how to use a Brainboxes BB-400 (Neuron IoT Controller), with a Brainboxes ED-560 (Ethernet to 4xAnalogue Outputs). The end example is a flow which will be able to set the outputs of a Brainboxes ED-560.
This FAQ explains different nodes inside Node-RED, which are used in creating an example for using a BB-400, with an ED-549. The end example is a flow which will be able to read the inputs of a Brainboxes ED-549.
The only nodes required for this tutorial are:

This FAQ will explain how Modbus TCP can be used with Node-RED to control the IO lines. Node-RED can be used on a PC or alternatively you can access a Node-RED instance on your BB-400.
This FAQ will describe how to use REST to control the IO lines using Node-RED. For more information on Node-RED please refer to the Node-RED FAQ , and for more information on WebSockets there is a Brainboxes FAQ What is the REST Protocol?
This FAQ will explain how to use read and write from the Serial port using a Node-RED instance on your BB-400.
