Supplies
Bread Bored
LED
6 Wires
Potentiometer
Arduino
Computer
Wire that connects Arduino to Computer
Attachments
Step 1: Connect Power Wires to Arduino
Take two wire for the negative and positive of the Breadboard. Attach negative wire to the Arduino GND. Then attach the positive wire to 5V.
Step 2: Then Connect Power to Potentiometer
Attach a new wire to A0, then place in the middle row of the Potentiometer on your bread bored.
Step 3: Connect Potentiometer to Negative and Positive
Using the other two rows of the potentiometers, put in same colum as the wires for Positive and Negative on the breadboard.
Step 4: Take Last Wire to Arduino 13
Put through a resistor, then LED. Have the resistor connect to the negative part of bread board.
Step 5: Code
void setup() {
// put your setup code here, to run once:
int ledPin = 13;
pinMode(ledPin, OUTPUT);
}
int potPin = A0;
void loop() {
// put your main code here, to run repeatedly:
int ledPin = 13;
digitalWrite(ledPin, HIGH);
delay(analogRead(potPin));
digitalWrite(ledPin, LOW);
delay(analogRead(potPin));
}
