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.

Hey everyone! I have used RFID systems in some of my previous Arduino Projects. I have always wondered how RFID systems work. Today I carried out a small research to test my idea and it was successful. Today, I will share my findings with you and explain you about how RFID works. The RFID system for Arduino includes MFRC522 RFID reader and some passive RFID tags. The tags are passive because they have no battery and use energy from the RFID reader to power their microchip. My Research and findings: I read that RFID systems work by electromagnetic fields, so with the concept in my mind, I took a small coil of wire and attached it to a Red LED. I chose Red because it consumes less power than other colours.  I connected my MFRC522 RFID reader with my Arduino Uno and uploaded the DumpInfo sketch. I used the MFRC522 library by GitHub community, and this sketch can be found in the Examples folder.  Go to File---> Examples--->MFRC522---> DumpInfo. I placed m...
