Skills Dev II : Yashasvi

Goal

- To creator a circuit that uses a photoresistor to collect data and display it, with a button to control input.

- To add potentiometer and button to the circuit. The potentiometer will control the led brightness and the button will switch it on and off.

Approach

Step by Step process on the DioT Labs site for Practice Exercise II

Creating a Circuit

Code

Setting up the sketch and connecting it to the Particle Cloud

int photoCellPin = A0;
int photoCellReading = 0;
int ledPin = D2;
int ledBrightness = 0;

void setup() {
    pinMode(ledPin, OUTPUT);
    
    Particle.variable("light", &photoCellReading, INT);

}

void loop() {
    
    photoCellReading = analogRead(photoCellPin);
    ledBrightness = map(photoCellReading, 0, 4095, 0, 255);
    analogWrite(ledPin, ledBrightness);
    delay(100);

Adding potentiometer to control the intensity of led and button to switch the circuit on and off .

When the potentiometer reading is high

High Potentiometer Output

When potentiometer reading is low

Low Potentiometer Reading

int photoCellPin = A0;
int photoCellReading = 0;
int ledPin = D2;
int ledBrightness = 0;

int buttonPin = D3;
int buttonState;

int potPin = A0;
int potReading = 0;

void setup() {
    pinMode(ledPin, OUTPUT);
    
    pinMode(buttonPin, INPUT_PULLUP);
    
    Particle.variable("light", &photoCellReading, INT);

}

void loop() {
    
    buttonState = digitalRead(buttonPin);
    
    potReading = analogRead(potPin);
    
    if(buttonState ==LOW){

        int ledBrightness = map(potReading, 0,4095, 0,255);
        analogWrite( ledPin, ledBrightness);
    } else{
        digitalWrite( ledPin, LOW);
    }
