Hey people, newbie here. Just made myself to Arduino yesterday and it's been great :D. Just some little (maybe stupid) question to ask to you guys (and of course, to Arduino gods XD).
Okay, I'm actually planning to make a prototype of smart road for a competition next year (and maybe Google Science Fair) using only Arduino and my PC as it's main computer. Okay, plan made. I've drawn all the diagram (nope.. i'm not sharing it.. XD ) and had planned all things that I need. I've also bought an Arduino Uno board and currently using it and my uncle is kind enough to give me 2 4051 and 2 4067 multiplexer for me to use in my project for now. Sweet!
So, as far as I know, Arduino Uno has only 6 analog input, while for my project I need minimum 16 inputs. Problem solved by using those multiplexers. So right now I get 8 to 16 inputs. I'm using this tutorial
and this tutorial
for how to connect Arduino to 4051/4067 multiplexer. By following those tutorials, I managed to get my muxes connected to arduino and read up to 16 photoresistors without any problem. Sweet! :D
Now, for the real stuff, I would like to use more 4051/4067 muxes to read up to 96 photoresistors. I could understand how to connect only one mux, but I don't know how to connect more.
So the question is, how do I connect more than one 74HC4051/74HC4067 multiplexer into an Arduino Uno? And how do I read inputs from them? Thank you very, very much.
In case if you guys would like to know my sketch, just refer to the links above. I copy and pasted them directly. ;) And hehe, please be nice with me. I'm a complete noob in arduino. Thank you again.
