I have an arduino Mega first of all and i am going to connect 10sensors like this:
[Ground] ---- [10k-Resister] -------|------- [LDR] ---- [+5v] | Analog Pin
So basically i need 10 analog pins which is found on the mega so it is OK. But when it comes to ground the mega have only 2 and only 5V supply.
So how can I connect 10grounds and 10 (5V) supply to all these sensors?
I was thinking of using an external breadboard? or Maybe the prototype shield but i dunno its use exactly.
so please someone experienced help me out abit please. :(
