I am starting to interested with raspberry pi 3, and i have some questions:
1. Can raspberry pi 3b run multiple projects at the same time ?
For example: let say i am going to connect to it some sensors: Motion sensor, Water plant soil sensor, A proximity sensor, Auto light switch etc.
Every sensor project can work alone with a python script, but can i write a program / software that can monitor all sensors and act on them
according to the software instructions ?
2. Is there enough GPIO pins for all sensors to work together ?
Can i add more input / output pins to use more sensors and other devices (like motors, LEDs, speakers...) ?
3. What programing language can i use to do all that (that includes a user interface on screen) ?
4. Does the power supply that comes with the raspberry good enough for all projects or should i add a PSU modules too ?
I have a lot of questions, but That's it for now.
