Potentiometer Fun! *woot*

We learned how to take input from a sensor such as a light sensor and feed back a range of values. I used these values to control the brightness of an led. 

Here I used the same programming code and pretty much the same breadboard setup to rig a pressure sensor to a light. 

The great thing is that it doesn't even take a lot of code to run:

const int potPin = A0;

const int led = 3;

int potValue = 0;

int newValue = 0;

void setup() {

  

  pinMode(led, OUTPUT);

  Serial.begin(9600);

  

}

void loop() {

  

  potValue = analogRead(potPin);

  

  newValue = map(potValue,0,1023,0,255);

  

  analogWrite(led, newValue);

  

  Serial.println(potValue); 

  

}
