Project Description:
This project demonstrates the basic functionality of an Arduino by blinking the built-in LED at one-second intervals. The program initializes the LED pin as an output and alternates between turning it on and off using the digitalWrite() function with a delay of 1000 milliseconds. This simple yet essential project serves as an introduction to microcontroller programming and timing functions.
Project Description:
This project implements a simple button-controlled LED system using an Arduino. Two push buttons are used to control two LEDs independently. When Button 1 is pressed, LED 1 turns on, and when released, it turns off. Similarly, Button 2 controls LED 2. The buttons are configured with internal pull-up resistors to ensure reliable input detection. This project serves as a fundamental introduction to digital input handling and can be expanded for interactive systems like switches, alarms, or user-controlled lighting.
Project Description:
This project demonstrates an alternating LED blinking system using an Arduino. Two LEDs are connected to different pins and flash in an alternating pattern with a 500ms delay. When LED1 is on, LED2 is off, and vice versa. This simple yet effective project introduces concepts of digital output control and timing using the delay() function. It can be expanded for visual indicators, signaling systems, or decorative lighting effects.
Project Description:
This project allows users to control the speed or position of a PWM output using a potentiometer. The potentiometer is connected to an analog input pin of the Arduino, and its value is read using analogRead(). The read value (0–1023) is mapped to a suitable PWM range (0–255) and sent to the servo motor through analogWrite(). This project is useful for applications like manual motor speed control, dimming LED brightness, or interactive robotic systems.
Project Description:
This project allows users to measure the distance of the obstacle which is away from the sensor. The ultrasonic sensor emits ultrasonic waves. The ultrasonic wave reflected from the obstacle and the distance is calculated by the esp32. This project is useful for applications like proximity alarm in car parking, automatic refill tank etc...
Project Description:
This project is a simple Simon Says memory game using an ESP32, LEDs, and push buttons. The ESP32 lights up a sequence of LEDs, and the player has to press the buttons in the same order. If the player gets the sequence right, the game adds a new step and continues. If the player makes a mistake, all LEDs flash to show Game Over, and the score is displayed in the Serial Monitor. This version does not use a speaker, so the game gives feedback only through LEDs and text messages.
Project Description:
A MAC address is a permanent, unique ID given to every device’s network hardware, like Wi-Fi or Bluetooth. It looks like six pairs of hexadecimal numbers (e.g., EC:64:C9:85:D5:94) and acts like a digital fingerprint. Unlike an IP address, it never changes and is mainly used to identify devices on a local network—for example, in ESP-NOW, it helps one ESP32 know exactly which device to send data to.
