In our last video on the Arduino we will make our previous example more complicated. Our microcontroller will be powered by an adapter and we will control rotation of a servo motor with a potentiometer. Then we will connect Arduino to a basic 2-line LCD and a potentiometer for controlling it. And finally combining all our knowledge we will construct a complex project where we will use a g-meter, a piezo disc and a battery case. In conclusion we will teach our microcontroller to work with Max/MSP and Pure Data programs.
