Arduino Projects by R

Hey everyone! You would have already read my previous project about controlling electrical appliances using IoT. In this page, I will be explaining you about the Internet of Things (IoT).  Refer to my diagram above.  When your device is connected to the internet, it is capable of sending or receiving information, or both. An IoT ecosystem consists of web-enabled smart devices that include microprocessors, sensors, actuators and communication hardware to collect, send and act on data that they receive from their environments. There are four main components in IoT system, which are: Sensors/ Devices connected to microprocessors Connectivity - Internet Data Processing - Cloud User Interface - Apps on mobile devices, for example: Blynk My previous project is an example of IoT. In this case, my IoT device was the smartphone which was connected to the internet. I used Blynk app for my project and when I tapped on the button widget, a signal was sent to the Bly...

Hey everyone! Today I am going to teach you about Internet of Things (IoT). This is my first IoT project and the first step towards home automation. Using IoT, interrelated computing devices are able to transfer data over a network without requiring human-to-human or human-to-computer interaction. In this page, you will see how I controlled my pedestal fan and soldering station with my smartphone. To learn about IoT, click here .

Hello everyone! Today I will teach you to make a security system using the vibration sensor module. The vibration sensor module comes with a SW-420 vibration sensor, and in this project, it senses the vibration across the solderless breadboard. Once a vibration is detected, a HIGH signal is sent to the Arduino Nano microcontroller. According to my sketch, the microcontroller switches on the LED and triggers the RF 433MHz transmitter module. The RF transmitter module sends a decimal code to the RF receiver module. According to my sketch, my Arduino Uno turns on the LED and makes the LCD display module show that a shock is detected. Hardware components used in this project Transmitter circuit Arduino Nano USB Type A to mini B cable (for Arduino Nano) Vibration sensor module RF 433MHz transmitter module LED Solderless Breadboard - Mini Male-to-Male Jumper wires (x2) - 10cm Jumpers (x9) - to reduce the usage of wires Receiver circuit Arduino Uno USB Type A/...

Hey everyone! We have already learnt to make Door Lock system using Arduino. Today I will be teaching you about the third version of this project. In the third version, you will be using RF 433MHz transmitter and receiver modules to control the Solenoid door lock.  Hardware components used in this project Voltage Regulator/ 12V DC power adapter Transmitter Circuit Arduino Nano USB 1.0 Type A to mini B cable (for Arduino Nano) Solderless Breadboard - Mini RF 433MHz transmitter module Push-button Male-to-Male Jumper wires (x2) - 10cm Jumpers (x7) - to reduce the usage of wires Receiver Circuit Arduino Uno USB Type A/ B cable (for Arduino Uno) Solderless Breadboard - Mini RF 433MHz receiver module Relay module - 5V single channel Solenoid door lock - 12V DC Male-to-Male Jumper wires (x4) - 10cm Female-to-Male Jumper wires (x3) - 20cm Setup Your setup must look somewhat similar to those shown in the pictures above.
