Lab 3 Potentiometers

Description:
I reassembled my LED circuit for one LED and added in a potentiometer in order to control the blinking speed and then brightness. Though I am still weak in terms of understanding how circuits work, I figured out that only new connection between the Ardunio and Breadboard was the 5V, which powered the Potentiometer's 5V. I then connected Potentiometer's grounding and analog cables to the Ardunio. 
 
Items used for this circuit:
- 1 Breadboard
- 1 220 resistor
- 3 long wires
- 1 Arduino board
- 1 Green LED
- 2 Potentiometers
- 3 Wires for each Pot (ground, 5v, analog)
 
Code used to Control 2 Pot LED:

int brightPin = A0;    // select the input pin for the blink potentiometer

int blinkPin = A1;  // select input pin for brightness potentiometer

int ledPin = 11;     // select the pin for the LED

int bright = 0;  // variable to store the value coming from the sensor

int blinkTime = 0;

void setup() {

  // declare the ledPin as an OUTPUT:

  pinMode(ledPin, OUTPUT);  

}

void loop() {

  bright = analogRead(brightPin); // read the value from the sensor:

  blinkTime = analogRead(blinkPin);

  Serial.println(blinkTime);

  analogWrite(ledPin, bright/4);// turn the ledPin to 

  delay(blinkTime);  // stop the program for some time

  analogWrite(ledPin, 0);  // turn the ledPin off 

  delay(blinkTime);  // stop the program for some time

}
