To find the Decoded Value (the unique IR signal for a specific button on your remote), you can use the Serial Monitor in the Arduino IDE to print the code that the IR receiver detects when you press a button.…
Use an ultrasonic sensor like the HC-SR04 to detect the water level in a tank and use the Arduino Nano to control the LED indicators based on the water level. Components you will need: Wiring: Here’s the wiring for the…
To build a Maze Runner game on your ESP32 with a joystick and a 0.9-inch OLED screen, I’ll outline the basic setup and give you the skeleton code to get started. The game will allow you to control a player…
To set up and use the ESP32-CAM with an FTDI module for uploading code and communication, follow these steps carefully. I’ll guide you through the hardware connections and provide you with an example code to get started. Components Needed: Step…
Creating a simple game using the ESP32, Joystick, and an OLED display can be a fun project! Let’s create a basic “Dodge the Block” game where a player controls a character (represented by a square) on the screen using a…
a Bluetooth module like the HC-05 or HC-06, which communicates over serial. The mobile app can send simple commands (like “F” for forward, “B” for backward, “S” for stop, etc.) via Bluetooth to control the motors. Steps: Motor Driver Shield…
This project demonstrates how to control two DC motors using an Arduino Nano, a L298 Motor Driver, and a Bluetooth HC-05 module. The motors can be controlled wirelessly from a mobile device using a Bluetooth app, which communicates with the…

To create a simple light-sensitive alarm system using a Light Dependent Resistor (LDR) and a buzzer, you can follow these steps using an Arduino microcontroller, LDR, and a buzzer. Here’s how to build the system: Components Needed: Circuit Diagram: Code…
The SmartTime Watch is an Arduino-based smartwatch that displays the current date and time on an OLED screen when you bring your hand near an IR sensor. Using a Real-Time Clock (RTC) module, the watch accurately shows the date and…
