Hi all - my first post
I’ve just stumbled across the Balena cloud and it looks like something that might suit my purposes further down the line.
Only thing is - I’m not finding it easy to start…
I’ve got the Raspberry Pi 4 up and running with the Balena OS, the device is now connected to Balena Cloud and has an air sensor project running (no actual sensor installed, but just so I know that the thing is working … and it is…)
The end goal is to have a nice GUI (Grafana) taking data from sensors (I think via Telegraf and mqtt) on the Raspberry Pi and possibly an Arduino for analog inputs and handling appropriate outputs with some user interactions via touchscreen buttons - I’m pretty sure this system has everything I want and more.
QUESTION 1 -Can this system handle input, the output of data from the device (seems so), and handle user interaction with buttons \ touchscreen via the web interface?
QUESTION 2 - More of a request… Can someone point me at a simple barebones test platform that triggers an LED attached to the GPIO on the Raspberry Pi and takes input from something (switch \ sensor etc) which it stores - I think once I’m at this level and have a starting point I’ll be able to learn (via copy and modify) the rest myself… The project Balena Sense (air quality monitor) was too complex for me to really understand and I need something easier to start with - or a ground-up tutorial on how to build this kind of application.
Is anyone able to point me to a basic program like this and get me started?
(I need something really simple to start with - the Docker system was new to me until yesterday)
