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
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 (HW-130) Connections: Explanation of the Code: Using a Mobile Bluetooth Control App:
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 Arduino via the HC-05 Bluetooth module. Component Connections: 1. Motor Driver (L298) to Arduino Nano … Read more

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 for the Light-sensitive Alarm System: How It Works: Adjustments: This system will provide a simple … Read more
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 time for 3 seconds, after which the display goes into an idle state, turning off … Read more
This project will allow you to control a small DC motor (representing the fan) based on motion detected by a PIR sensor. When the sensor detects motion, the motor will turn on, and when no motion is detected, the motor will turn off. Components Needed: Step 1: Circuit Connection Since you will not be using … Read more
Here’s how you can build a water level monitoring system using an Arduino and a water level sensor, with the water percentage displayed on an I2C LCD. Components Required: 1. Wiring the Components: Water Level Sensor: I2C LCD: 2. Arduino Code: Here’s a simple example code using an analog water level sensor and displaying the … Read more
This project involves creating a simple snake game using an Arduino, a joystick for controlling the snake, and an OLED display to show the game graphics. The game will use basic components, including a joystick module to control the snake’s movement and a OLED display to render the snake and the game environment. Components Required: … Read more
