 ====== Analog-In/Digital-Out (Potentiometer and LEDs) ======
-==Intro==
+===== Intro =====
-HiTechnic's Prototype Board allows analog input and digital input and output to be easily achieved with a breadboard for circuit prototyping and a LEGO NXT from the Mindstorms robotics kit. This board connects to the standard NXT sensor port and communicates over an I2C serial bus.<br>

-The six LEDs are connected to six pins that will act as a digital out. The potentiometer's variable resistance causes a variable voltage to be read at the analog input AO. This voltage is read in as a number between 0 and 1024. The LEDs are lit up linearly as the potentiometer is rotated.<br>
