Today I will talk about how you can use actuators in BlueMix. I will build further on the app that monitor the temperature and light sensors in my room, and this time it will publish MQTT messages on the broker that is picked up by and viewed on an LCD display.
This video build on my previous video called “Internet of Things – Use Sensor Data In BlueMix”, so please check that out for details on how to use sensor data in BlueMix. In this video, I will modify the Node-RED application to send the output messages to another Arduino with an LCD display. To send messages to devices in BlueMix, you have to register the device, and to do that you need to sign up for the Internet of Things Foundation, register your devices, and also set up a real Internet of Things service
