ArduinoSerialAnalogWires

Connect some wires and see stuff happen!

How to?

Download the project file or copy the code straight to your ide!

After starting up the ide, connect your arduino and start the serial monitor. Now, take a wire and connect it to the ground and the other end to analog in 1.

Have fun with this extremely simple peace of code ment to be a school demo!

long randNumber;
int analogPin = 0;     // Where to connect the first end of the wire
int val = 0;         // The variable to store if the wire is connected
int lastval = 0; // this is the last value buffer used later for some nice random number logic :3 



void setup()

{
  Serial.begin(9600);              // Lets setup the serial
  val = analogRead(analogPin);
  pinMode(LED_BUILTIN, OUTPUT);
  randomSeed(analogRead(0));
}



void loop()
                    {
  val = analogRead(analogPin); // if we dont get a solid analog input well just call it a day
  if (val > 0) {

          val = analogRead(analogPin); // we store the output of analogRead from pin 0
            lastval = analogRead(analogPin); // we save the value for a second
                Serial.println("\n"); // we print a newline
            Serial.println("Please connect the cables :3"); // and we prompt to connect the cables


            
            Serial.print("Analog reports: "); // lets print what the analog reports just for fun
            Serial.print(val); // we print (val) wich is analogRead 0´s value
