Build your own Wi-Fi Repeater or Range extender using NodeMCU to connect all your IoT Devices We are in the Internet of Things (IoT) generation! These days, you can control your home gadgets/devices like air-conditioner, room heater, water heater, etc. remotely from anywhere and the device to do this can easily be built or purchased off the shelf. Over the course, we have also built a few IoT based home automation projects using Arduino, ESP, and Raspberry Pi. But… |

Fastest Arduino RC Car using Coreless DC Motors and nRF24L01 RF module RC cars are always fun to play with, I am personally a big fan of these remote-controlled Cars and have played (still do) with them extensively. Most of these cars today provide a huge torque to handle rough terrains, but there is something that was always lagging, its Speed!!.. So, in this project, we will build a totally different type of RC car… |

Different Types of Wireless Power Transfer Technologies and their Working Every electronic system or device needs electric power to operate, whether it is from your walled AC supply or a battery. This electric power cannot be stored infinitely in any rechargeable device like batteries, condensers or Supercapacitors. So any portable devices like laptops or mobile phones are needed to be connected to AC power lines to recharge their batteries… |

Getting Started with M5Stack Tab5: ESP32-P4 Touchscreen Development Board Large touchscreen development boards are useful when a project needs more than a microcontroller and a few expansion pins. A display, camera, audio system, wireless connectivity, storage and industrial interfaces can turn the development board itself into the starting point for a complete embedded product. The M5Stack Tab5 takes this approach with a 5-inch 1280 × 720… |

SensorTile.Box Review – Test and Validate your Wearable Ideas Instantaneously A few years back, if someone were to tell me a watch could not only tell time but can also measure the heart rate and track calories, I would be blown away by it. Today more than a million people, including me own a wearable fitness tracker and it is forecasted that the market for wearable devices would reach $57,653 millions by 2022. From smart glasses to Diabetes… |

DIY Arduino Wireless Programming Shield using Bluetooth Module While doing projects using Arduino, we always need to connect Arduino to PC in order to upload the program in it. But sometimes it is very uncomfortable to always connect the board with PC as if it is a robotics project then you always have to move the robot near to labtop to re-program it. This problem can be solved by programming the Arduino wirelessly. So here we are… |

An Introduction to Sigfox Technology – Basics, Architecture and Security Features The race for wireless technology started long back in 1890’s when Marconi built the world’s first radio station and introduced wireless telegraphy, which completely re-defined the way how humans exchanged information back then. Today, we have advanced with many new cellular technologies to transmit large amount of data wirelessly to anyone living at even the deepest corner… |
