// Setup the essentials for your circuit to work. It runs first every time your circuit is powered with electricity.
// Setup Serial which is useful for debugging
// Use the Serial Monitor to view printed messages
while (!Serial) ; // wait for serial port to connect. Needed for native USB
// Main logic of your circuit. It defines the interaction between the components you selected. After setup, it runs over and over again, in an eternal loop.
// You have chosen a controller that doesn't have code yet.
// You may request a similar combination but with Arduino Uno and try to use the Arduino Uno libraries & code - some may work, but we can't guarantee it.
// Make sure your Arduino IDE supports the chosen controller. If not visit http://playground.arduino.cc/Main/BoardsManagerSupport
