After long time I needed to reprogram my ESP8266 NodeMCU. Looking back into my older blogpost I came to know that I have not written any note on how I programmed it when I used it for the first time. So this time I wanted to write a note on how I a…
I had disassembled the Arduino Blutooth controlled RC car that I had built many months ago for adding crane part to the car. I did not successfully completed it but I was/am close to it. I wanted to build the crane part on top of the arduino blueto…
Motion detection is a critical feature in many security systems and automation projects . One of the most common sensors used for this purpose is the Passive Infrared (PIR) sensor . PIR sensors are reliable, cost-effective, and easy to integrate in…

Motion detection is a critical aspect of security systems and automation projects. Passive Infrared (PIR) sensors are widely used for detecting motion due to their reliability, cost-effectiveness, and ease of integration. This blog post explores a …
It is quite simple to write ESP8266 led on/off code without using WiFi connectivity but that is not the advantage of using ESP8266. The advantage of using ESP8266 is to use WiFi connectivity for wireless control of devices like a LED. In this ESP8…
I previously made a wifi controlled car in which I used 4x1.2V , lithium ion batteries for power supply. The car was moving very slow so I was thinking to change the battery and put more voltage supply. After many days, I now have changed the batte…
ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by Espressif Systems. It is often used in Internet of Things (IoT) projects, as it allows devices to connect to Wi-Fi networks and communicate with …
NodeMCU ESP8266 is a low-cost, open-source WiFi connectivity capable SoC(System on Chip) microcontroller that is widely used by hobbyists, makers, and professionals in various IoT projects. It is based on the ESP8266 chip and comes with built-in WiF…
What is aREST API? aREST API (or Representational State Transfer Application Programming Interface) is a popular architectural style for building web APIs. It is a standard way of exposing resources and services over the internet in a way that is e…
