SMART PROJECTS

Arduino and ESP32 projects with full tutorials, source code, components and wiring instructions.

🎬 VIDEO TUTORIAL

📦 COMPONENTS

Arduino Uno / ESP32
TFT or OLED Display
Sensors
Push Buttons
Buzzer
Jumper Wires

🔌 CONNECTIONS

Display VCC → 5V / 3.3V

Display GND → GND

SDA / MOSI → Arduino communication pin

SCL / SCK → Arduino communication pin

Sensor OUT → Analog / Digital input

Buzzer → Digital output

💻 SOURCE CODE

 #include <Arduino.h> #define BUTTON_PIN 2 #define BUZZER_PIN 3 void setup() { pinMode(BUTTON_PIN, INPUT_PULLUP); pinMode(BUZZER_PIN, OUTPUT); Serial.begin(9600); } void loop() { int buttonState = digitalRead(BUTTON_PIN); if (buttonState == LOW) { tone(BUZZER_PIN, 1000); Serial.println("Button Pressed"); delay(200); noTone(BUZZER_PIN); } }

📖 HOW IT WORKS

This page is designed as a complete project tutorial. For every new Arduino project, add the YouTube video, replace the component list, write the exact wiring instructions, and paste the complete tested source code.
