To build your Arduino car with IR remote and receiver, using the L298N motor driver to control the motors, here is the wiring guide based on the code you provided. Components Required: Wiring Connections: Power Considerations: Testing:

To control an LED and a Buzzer using an IR remote. When a specific button on the IR remote is pressed, the LED will light up, and the buzzer will sound. Components Needed: Wiring Instructions: Arduino Code: How the Code Works: Testing: Conclusion: This project demonstrates how to use an IR remote to control electronic … Read more

In this project, you will learn how to build an Arduino-controlled car using an IR remote and receiver. This step-by-step guide covers everything from wiring the components, such as the L298N motor driver and DC motors, to writing the Arduino code that allows you to control the car’s movements. Components Required: Step 1: Wiring the … Read more

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. Here’s how you can do that: 1. Wiring the IR Receiver to Arduino 2. Upload … Read more

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 LEDs: Code: Here’s a simple Arduino code to control the LEDs based on the water … Read more

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 (typically represented by a simple symbol) with the joystick on the OLED screen to navigate … Read more

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 1: Wiring Connections (ESP32-CAM + FTDI Module) The ESP32-CAM works at 3.3V logic, but the … Read more

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 joystick, and they must avoid falling blocks. The blocks will fall from the top of … Read more
