Overview

In this lesson, you will rewrite Blink code. However, your delay function change according to your analog value. To do this lesson, you need a 10k potentiometer. The potentiometer will be connected to the ESPcopter’ analog pin which is 2. You can find out this pin by using ESPcopter’ pin out diagram.

/*
Analog Input

*/

int sensorPin = A0; // select the input pin for the potentiometer
int ledPin = 10; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor

void setup() {
// declare the ledPin as an OUTPUT:
pinMode(ledPin, OUTPUT);
}

void loop() {
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
// turn the ledPin on
digitalWrite(ledPin, HIGH);
// stop the program for <sensorValue> milliseconds:
delay(sensorValue);
// turn the ledPin off:
digitalWrite(ledPin, LOW);
// stop the program for for <sensorValue> milliseconds:
delay(sensorValue);
