Esp8266 based home automation system project is designed to control home devices using Wi-Fi through a website or any android app which has internet connection. As you I have already posted a project on Bluetooth based home automation system and gsm based home automation system. Both these embedded system projects have limitation of distance and availability of network. For example in case of hc 05 based pr ...

Tv remote controlled home automation system using pic microcontroller. With the help of a TV remote, we would be able to control different loads. Each button on the remote will have different functionality i.e. will turn ON/OFF different loads .TV remote will send a unique/different IR signal on each button press. TSOP (IR Receiver) will catch the signal and output a binary waveform (unique for each button) ...

When doing astronomy observing at night preserving night vision is critical. This requires using the minimum amount of light that makes the sky charts readable. What is this minimum level depends on how dark are your surroundings, how much time you have spent in darkness, how well your eyes adapt for night vision, what type of charts are you using, what object are you observing, and so on. My old astronomy ...

Introduction The problem was this...at Redeeming Grace Church we were meeting in a public school prior to moving in to our permanent facility. Each Sunday morning we would bring in three large percolating coffee pots to brew regular, decaf, and hot water for the mid-service break time. Each pot drew 9 amps. Because the average 120VAC power receptacle "outlet" in the USA is protected by a 20-amp breaker, thr ...

Introduction On request I have built a microcontroller-based doorbell system which is being used in an industrial environment. This is the basic function: When you push the bell-button, a horn will sound for about 10 seconds. At the same time a light, which keeps burning until someone pushes a reset-button, will be activated. The system has a lot of features: There are 2 different lamp outputs: these can be ...

This Instructable will take you on my journey to replace my old Netflix/Vudu Bluray player with a PC based entertainment station for my LCD projector. I wanted to be able to access and control Netflix, Hulu, Youtube, Crackle, NBC, ABC, and the Weather Channel using only a simple remote control. Along the way, I'll give you the full details you need to replicate this project, but at the same time I'm going t ...

About a year ago I started on a project to make a temperature controlled nightlight. I was inspired by seeing these lovely LED lamps styled as mushrooms growing out of pieces of wood. Those mushrooms were made out of glass, which was somewhat beyond my skills. However I then saw some had used translucent sculpey to make mushroom nightlights on instructables. So with that discovery it seemed like it would be ...

24 Channel USB Connected LED Controller, upto 1A per Channel This device is designed to be a versatile high-current LED controller, with the ability to sink or/and source currents up to 1A per channel with dissipation of up to 2.5w per channel. The various jumpers and transistor placement allow the device to control many different types of LED configurations with LED voltages of up to 36v. Easily controls 5 ...

The goal of this project is to create a device that is capable of outputing VGA signals to a CRT monitor inorder to display figures, text and characters. Timing is a core essential in this project. If the signal is off by even 1 microsecond, the signal synchronization with the CRT display will be lost and forced to resync. This will be done using a Microchip PIC microcontroller at 4 MHz clock speed. The pro ...

MikroEleketronika demonstrates how to build a simple home alarm system that has the capability of sending SMS to a predefined cell phone number when intrusion is detected. This project is based on StartUSB for PIC board, a small development board for PIC18F2550, which is preprogrammed with an USB bootloder so that no additional programmer is required to load the firmware. The SMS portion uses a SmartGM862 B ...
