I'd need some advice about a project I'd like to start. I want to do on-board measurements in a train model, with pressure transducers, accelerometers and inclinometers.
I've Googled how to acquire voltages using Arduino and save it to a SD card, which looks quite trivial. Using an Arduino Mega would give me 16 analog inputs but I would like to use more. So I thought about synchronising different Arduinos to get more analog inputs.
Does it look feasible? Ideally I could add several Arduinos to acquire even more data at the same time.
Thanks for any advice that could help me.
