Normally these modules can be programmed directly using the Arduino IDE, but for this project, we have to flash the firmware on NodeMCU. Also, it has several power input options (input using a micro USB port and two types of external power input (5v VCC input and 3.3v VCC input) and can be used as an access point. It can also be programmed in Arduino IDE through the micro USB interface (with onboard flash management IC) and it is a programmable wifi transcriber module that’s the best choice for wifi networking, mash networking and has 802.11 international standard 12E wifi chip, onboard 3.3V regulator and onboard Antena. It is an open-source IoT development platform, a combination of the wifi module and the features of Arduino (Microcontroller). The Nodemcu ESP8266 is the main and only component so, I would like to describe some basic features and specifications too. Follow the simple steps given below to build your low-cost wifi repeater or range extender. For this, you don’t need to build any hardware circuit and you need not be an expert in electronics. So, today I have shared a solution that quickly builds weekend projects within half an hour. There arises the need for low-cost solutions (less than one third compared to the price of any commercial wifi repeater) only for range-extending. It is for this reason that wifi repeater or range extenders are required but commercial wifi repeaters available in the market are very costly which is not a feasible option for all.

But using broadband connection has its limitations like sometimes wifi signal drop (especially for 2.4 GHz band, occupied with more interference) from room to room or floor to floor. But for every Wi-Fi-based IoT-enabled devices, you need an Internet connection or you can say uninterrupted Internet/Wi-Fi connectivity. Over the course, we have also built a few IoT based home automation projects using Arduino, ESP, and Raspberry Pi.

remotely from anywhere and the device to do this can easily be built or purchased off the shelf. 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.
