I'm as new as you can be at Arduino programming and specific electronics, so I don't even know if I'm asking the correct question.
I've ordered an Arduino a breadboard and some PCBs and now I'm looking for a few parts that I should buy in order to get some basic projects done.
I'd like to start with a garden automation project, a fairly simple one. Humidity sensors, temperature sensors and a water pump.
Can I connect all (4) of the humidity sensors to a single local circuit and then connect that to the board so I can limit the number of input pins used? I'd still need to get independent readings from the sensors. Or would I need to use another board incorporating RF/Wireless/Bluetooth modules to receive the information and then send it to the board for further processing?
I'm sorry if what I just said makes no sense and I thank you for your time. All I have is low-mid level electronic related experience. Battery checkers, Power supplies, basic light sensors, PCB making ETC.
