Simple force sensor input and buzzer output

The day before I was having problem with Force Sensor input and Buzzer Output. So I tried to it again on a completely separate circuit.

Here’s the codes.



//try buzzer and force sensor
int buzzPin = 5; PWM 5
int forcePin = 5; Analog 5
void setup()
{
pinMode(buzzPin,OUTPUT);
}
void loop()
{
int forceVal = analogRead(forcePin);
int thisPitch = map(forceVal, 100, 1000, 500, 600) //freq 500 to 600
thisPitch = constrain(thisPitch,500,600) //safety net
if (forceVal > 100)
{
tone(buzzPin,thisPitch);
}
else
{
noTone(buzzPin);
}
}
