Tone Output

* always need to check the LED’s longer side and shorter side....

Tone output using an Arduino

with 1 FSR

void setup() {
}

void loop() {
int sensorReading = analogRead(A0);

float frequency = map(sensorReading, 200, 900, 100, 1000); -> changed it to (..,100, 200, 400, 600) because my sensor only detected <850

tone(8, frequency, 10);
delay(10);
}

with 3 FSR

void loop() {
for (int thisSensor = 0; thisSensor < 3; thisSensor++) {

int sensorReading = analogRead(thisSensor);

if (sensorReading > threshold) {
tone(speakerPin, notes[thisSensor], noteDuration);

Servo Motor Control using an Arduino

#include "Servo.h"

Servo servoMotor;

int servoPin = 9;
long lastMoveTime = 0;

void setup() {
Serial.begin(9600);
servoMotor.attach(servoPin);
pin 9 to the servo object
}

void loop() {
int analogValue = analogRead(A0);
Serial.println(analogValue);

int servoAngle = map(analogValue, 0, 1023, 0, 179);
-> changed it to (.., 0, 850, 0, 179) because my sensor only detected <850

if (millis() - lastMoveTime > 20) {
servoMotor.write(servoAngle);
lastMoveTime = millis();
}
}
