Arduino LED chaser using potentiometer and Arduino Uno.

Element required:
● 1 x 840 pin breadboard
● 1 x potentiometer
● 12 x 5 mm led
● 12 x 220 Ohm resistor
● 16 x jumper cable (male - male)

Programming :
int sensor = A0; 
int led1=2;
int led2=3;
int led3=4;
int led4=5;
int led5=6;
int led6=7;
int led7=8;
int led8=9;
int led9=10;
int led10=11;
int led11=12;
int led12=13;
int t;
int sensorValue = 0;

void setup() {
  // put your setup code here, to run once:

pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
pinMode(led4, OUTPUT);
pinMode(led5, OUTPUT);
pinMode(led6, OUTPUT);
pinMode(led7, OUTPUT);
pinMode(led8, OUTPUT);
pinMode(led9, OUTPUT);
pinMode(led10, OUTPUT);
pinMode(led11, OUTPUT);
pinMode(led12, OUTPUT);

}

void loop() {
  // put your main code here, to run repeatedly:
sensorValue = analogRead(sensor);
t = 10 + (sensorValue * (250.0 / 1023.0));
