Hey guys, I have a question regarding capacitors :
I recently assembled a bare-bones "Arduino" using an ATMega328P-PU IC, and having followed the instructions on two different tutorials ( one by Nick Gammon and the other an Instructable ) I'm trying to reconcile some differences between their builds.
Nick Gammon places two ceramic 0.1uF capacitors on either side of his breadboard, between power and ground, which I understand eliminates noise and current dips.
The Instructables tutorial however lacks these ceramic capacitors, but includes a 5v voltage regulator LM7805 and two 10uF electrolytic capacitors.
My build has BOTH the voltage regulator and the ceramic capacitors ( and works fine ), but I'm wondering if the ceramic capacitors are unneeded since I'm choosing to have the voltage regulator?
Any feedback is greatly appreciated, thanks!
