Use Serial.read() to control the Arduino We learned we needed to enter or "send" the data to the serial monitor each time we input new data. Play Notes on the Arduino int inputChar; void setup () { pinMode(12,OUTPUT); Serial.begin(9600); } // this code will play the A major scale which has 3 sharps, C#, F#, and G# void loop(){ if (Serial.available() > 0) { inputChar = Serial.read(); if (inputChar == 'a'){ tone(12,1760); } if(inputChar == 'b'){ tone(12,1976); } if(inputChar == 'c'){ tone(12,2216); } if(inputChar == 'd'){   tone(12,2348); } if(inputChar == 'e'){   tone(12,2636); } if(inputChar == 'f'){   tone(12, 2960); } if(inputChar == 'g'){   tone(12, 3324, 400); } } } Above is the code we used to play different tones corresponding to an A major scale. We used a Piezo buzzer and had the same circuit set-up as in previous labs. Create some LED flashing r...
