if you had any suggestions on parts I should buy for general development appart from the breadboard, especially for Arduinos and RPi?
Thank you
Regards
Well thats a common question and everyone has their own views on that, partly down to cost as well.
My humble take on your current situation; you have got a good goal to aim for in your multifunction project.
However its way to vast and complex for you to handle or for anyone to give meaningful help at your current level of micro knowledge.
I would suggest now is the time to start learning the code using the Arduino Example sketches and doing the basics like Blinking a Led and working up from there.
Everyone hasd their own way to learn, but following a tutorial series like this might help you ?
Break your project down into small managable modules, for example after those basic examples learn how to use a temperature sensors, many around, but the DS18B20 pre wired type is a good one.
As you produce an array of such modules your coding skill will naturally enable you to pull things together into you final project.
As for parts, again its down to personal choice and money.
For modules I would suggest a DS3231 RTC real time clock module and a LCD shield which give you input buttons and a useable screen, both quite cheap on ebay. Do not go for a large tft screen at this stage, stick to a 16x2 or 16x4 unit,
For components form either some local or mail order shop, a small pack of leds, one or two tactile switches and a small mixed pack of resistors.
Lots more you can buy, but that should be obvious to you as you develop.
