// Tilt Pitch Control: Tilt Code Lab Mini + Sensor Trio Add-On right to increase the pitch playing on the speaker, and left to decrease it int pitch = 0; //create a variable named pitch to hold the hertz value that you are playing on the speaker void setup() { pinMode(2,OUTPUT); //Speaker pinMode(A4,INPUT_PULLUP);//Left Tilt Sensor pinMode(A5,INPUT_PULLUP);//Right Tilt Sensor } void loop() { if(digitalRead(A5)==LOW){ //If Code Lab Mini is tilted right... pitch++; //increase the value of pitch by 1 delay(5); //Pause for 5 milliseconds to control the speed of the change } else if(digitalRead(A4)==LOW){ //If Code Lab Mini is tilted left... pitch--; //decrease the pitch variable by 1 delay(5); //Pause for 5 milliseconds to control the speed of the change } tone(2,pitch); //use the variable as the tone to play on the speaker if(pitch < 0){ //if pitch goes below 0... pitch = 0; //reset pitch to 0 so you don't have negative sound values that you can't hear. } } // (c) 2023 Let's Start Coding.
