ESP8266 based Smart Plug to Make Your Home Appliances IoT Enabled

Ever since I started to work with the ESP Wi-Fi Modules, I always wanted to build a smart Wi-Fi socket that enables me to control my AC loads wirelessly through smart phone. While products like these are already available in the market, like the popular Moko WiFi Smart Plug or Sonoff, they are a bit expensive and on top of that it doesn’t give you the joy of building your own.  So, in this project I will show you how you can build your very own Smart plug using ESP8266 Wi-Fi module. The device that we built can easily be plugged into any exiting AC socket and then on the other end you can connect the actual load simply by plugging it into this socket on our device. After that just keep the main switch of your socket always on, and you can control your Load directly from your Smartphone. Fun right? Check out the project at below link ….

Arduino Sleep Modes and How to use them to Save the Power
Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem almost every controller comes with a sleep mode, which help developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power saving mode by turning off the unused module.

DIY Pick and Place Robotic Arm using ARM7-LPC2148 ARM Microcontroller
In this tutorial we will use a 3D printed robotic ARM that was built by following the procedure in thingiverse. The ARM uses 4 servo motor for robotic ARM movement. If you do not have a printer, you can also build your arm with simple cardboards like we built for our Arduino Robotic Arm Project. For inspiration you can also refer to the Record and Play Robotic Arm that we built earlier using Arduino.

12V 1A SMPS Power Supply Circuit Design

In this tutorial we will cover how to build a 12v SMPS circuit that would convert AC mains power to 12V DC with a maximum current rating of 1.25A. This circuit can be used to power small loads or even be adapted into a charger to charge you lead-acid and lithium batteries.
