I am new to Arduino, and this is my first time in learning it (yeah i know i'm a bit outdated
). My question is, is there any ways of making my own circuit board (not using any completed boards in the market by Arduino) with requirement of taking many data inputs from electrical and meteorological parameters? There are 4 sensors that will be going to use in electrical part while for meteorological part, it is having 3 sensors. And those sensors are used for 1 set of system and for the whole project I will be having more than 1 set of the system (let say 13 sets). I am thinking to use more than 1 of ATMEGA328, but still not decided yet on how to do it. Any suggestion and idea from you guys? Thank you in advance!
