We connect three wires to the Arduino board. AnalogReadSerial:read a potentiometer, print it’s state out to the Energia Serial Monitor. Fade :demonstrates the use of analog output to fade an LED. ReadAnalogVoltage :reads an analog input and prints the voltage to the serial monitor. Rotating the potentiometer knob changes the brightness of the LED light. Function Introduction.
