ESP32 Simulator - 2022 - Photosensor-Embedded Systems

Introduction

Light sensor/photosensor projects find their application in lighting applications, solar control projects and more. Arduino UNO is simulated on the Wokwi Arduino simulator. You can learn Arduino programming faster and easier. Let us get started 😀

Simulation

Code

#include <LiquidCrystal_I2C.h>
#define LDR_PIN 2
LiquidCrystal_I2C lcd(0x27, 20, 4);
void setup() {
pinMode(LDR_PIN, INPUT);
lcd.init();
lcd.backlight();
}
void loop() {
lcd.setCursor(2, 0);
lcd.print("Question: ");
if (digitalRead(LDR_PIN) == LOW) {
lcd.print("FALSE!");
} else {
lcd.print("TRUE! ");
}
delay(100);
}
