This Node-RED Introduction 101 repository is useful as a pre-hackathon webinar introduction to Bluemix, Watson Cognitive Services and Node-RED. Many of the projects at your hackathon could use Node-Red on the IBM BlueMix platform to integrate devices, APIs and online services. It is essential that all participants have foundational knowledge of this technology prior to attending the event.
Webinar Topics:
1. Creating a Bluemix Account
2. Bluemix Overview
3. Watson Cognitive Services Overview
4. Node-Red Overview
- Concept of flows and nodes
- Input & Outputs
- Debug and inject nodes
5. Check out additional Node-RED flows in my [TJBot-Node-RED](https://github.com/johnwalicki/TJBot-Node-RED) repository.
This Node-RED-Introduction101 repository includes a presentation, [Node-RED Flows](NodeRED-Intro-examples.flow), Node-RED Flow [screenshots](/Screenshots/) that can be used during a pre-hackathon webinar.
Presenter: [John Walicki](https://github.com/johnwalicki/)
