Wireless Weather Station

Wireless weather station u sing Arduino   Dear friends welcome back! Today we are going to build a wireless weather station project using Arduino.Without any further delay, let’s get started!  A Wireless Weather Station with a big 3.2” Color TFT display. The project is up and running,and it displays the current date and time, the indoor temperature and humidity, and the outdoor temperature and humidity. The readings of the outdoor sensor are updated every second in order to demonstrate that we have a reliable communication link established with the transmitter which is outside at a distance of 5m. The readings of the indoor sensor are updated once every minute. The heart of the project is the fast Arduino Due, there is no flickering of the screen when the values are updated. Let’s now see the transmitter.  The transmitter is much simpler. It consists of an Arduino Nano, a DHT22 sensor and the NRF24L01 wireless transceiver module. The transmitter reads the temperature and ...

Motion Detector Camera

Motion Detector With Photo Capture Camera   Hello friends!! Welcome to This Blog. In this Blog, we will make a motion sensor detector with photo capture using ESP32CAM and the PIR module. The logic behind is when the PIR sensor detects any motion, the ESP32CAM will start taking the pictures. So you can use this project as a security camera. In thisblog, I will share the circuitdiagram, Arduino sketch, and the component list, so after reading the complete article you can easily make this project. Now ESP32 CAM is a small camera module that has ESP32S chip on the back and some GPIO pins to connect peripherals and it also has a micro-SD card slot, where you can insert the micro-SD card and store the pictures. Now before going to the circuit diagram and Arduino sketch, let me give you a quick overview of this project.  Components Required ESP32-CAM  PIR Motion Sensor Module BC547 NPN Transistor 220ohm, 1k, 10k Resistor. LED 5-mm FTDI 232 USB to Serial Interface board 5 v...

Obstacle Avoiding Robot

Obstacle Avoiding Robot using Arduino and Ultrasonic Sensor A simple project on Obstacle Avoiding Robot is meant here. Robotics is a stimulating and fast growing field. Being a branch of engineering, the applications of robotics are increasing with the advancement of technology.The concept of Mobile Robot is fast evolving and therefore the number of mobile robots and their complexities are increasing with different applications. There are many kind of mobile robot navigation techniques like path planning, self – localization and map interpreting. An Obstacle Avoiding Robot may be a sort of autonomous mobile robot that avoids collision with unexpected obstacles. In this project, an Obstacle Avoiding Robot is supposed. It's an Arduino based robot that uses Ultrasonic range finder sensors to avoid collisions.  Components Required Arduino NANO or Uno  🛒 HC-SR04 Ultrasonic Sensor  🛒 LM298N Motor Driver Module  🛒 5V DC Motors  🛒 Battery  🛒 Wheels 🛒 Chassis...

Bidirectional Visitor Counter

Bidirectional Visitor Counter using Arduino A bidirectional visitor counter using Arduino may be a reliable circuit that takes over the task of counting variety of Persons/Visitors within the Room very accurately. if somebody enters into the space then the Counter is incremented by one and also leaves it might be incremented. MATERIALS REQUIRED: Arduino IR Module 16*2 LED 5V Relay Resistor(1K,220 ohm) Breadboard Jumper Wires The total number of persons inside the space is Shows on the 16X2 LCD module. The microcontroller does the work it receives the signals from the sensors, and this signals operated under the control of software which is stored in EPROM of Arduino. There are two IR Modules are used. first, one are often wont to count the amount of persons entering a hall within the up mode at the doorway gate. and therefore the other can count the amount of persons leaving the hall by decrementing the count at the exit gate. In this Project will helps to Wastage of electricity. In ou...
