Step 5The Circuit
Schematics V2:
+If you're using a power supply that is slightly over 5V than you'll NEED a regulator...
(there are alternatives... but... since a 7805 costs like... ermm about 30cents a piece... I'm sticking with it)
+The potentiometer is optional, but you should increase a bit the resistance if you decide to ignore it... (otherwise your girlfriend, or whoever uses this, might not get any sleep at night)
The circuit schematics is shown in the picture bellow, To get the image on it's original size, click the "i" on the top-left corner of it
Assembly:
+I used one of my standard breadboard-like perfboard
+
USB connector:
always double check the pinout (see picture)
Pin 1 = Vcc
Pin 4 = Gnd
