A switched capacitor voltage converter performs energy transfer and voltage conversion using capacitors. There are mainly two types of switched capacitor voltage converters, first is the voltage inverter circuit and the second is the voltage doubler circuit. These types of circuits are commonly known as charge pump circuits.
In this project, we will…
When designing an electronic circuit, there are lots of situations when a circuit requires different values of voltage and current sources. For example, when setting the preset voltage for an Op-Amp, it is very common to use a potential divider circuit to obtain the required voltage values. But what if we need a specific value of current? Similar to the voltage divider,…
Electronic gadgets like Mobile Phones and IPods have made our lives a lot easier. But, all of them suffer from one common drawback of charging them at regular periodic intervals. This becomes a problem when we are traveling or at a place where electricity is not available. Also using renewable energy source is quoted as the next generation fuel for all our electricity…
In previous tutorials we have seen How we can build an Amazon Echo Speaker and then how can we control any Raspberry Pi GPIO using Alexa Voice. Now we are making an IoT project to control home appliances from anywhere in the world using AlexaPi and ESP-12E (or any ESP board).
Hardware Requirements Raspberry Pi with…
Have you ever thought about a speaker which can be controlled by your voice!!! What if we can control our home appliances this way and make these appliances smarter? Voice assistants becoming more popular as we are heading towards an era of AI and IoT based systems. You have heard about Google Assistant, Apple Siri and Amazon Alexa. These all are Voice based AI systems, what…
Choosing a communication protocol for communication between microcontrollers and peripheral devices is an important part of embedded system. It is important because the overall performance of any embedded application depends on communication means as it is related to cost reduction, faster data transfer, long distance coverage etc.
In the previous…
RFID (Radio Frequency Identification) is an inexpensive and accessible technology. It can be used in many applications such as access control, security, asset tracking, people tracking, etc. You have seen the RFID Door Lock system in Hotels, offices, and many other places where you just have to place the card near RFID reader for a second and the door will be opened. We used…
The STM32 Development Board housing the STM32F103C8 Microcontroller is getting increasingly popular thanks to its ARM Cortex M3 architecture, it has high operational speed and more peripheral options. Also since, this board can be easily programmed using the Arduino IDE it has become a preferable choice for many hobbyists and engineers…
A voltage-to-frequency converter (VFC) is an oscillator that outputs a square-wave, whose frequency is linearly proportional to its input voltage. The output square wave can be directly fed to a digital pin of a microcontroller to accurately measure the DC input voltage, which means the input voltage can be measured using 8051 or any other microcontroller which does not have…
Hi guys, welcome to today's tutorial, one of the good things about the Raspberry Pi is the great ability and ease with which it gives you the opportunity to connect devices to the internet especially for Home Automation Related Projects. Today we are going to explore the possibility of controlling AC appliances with the click of buttons on a webpage using internet.…
In this project we are going to interface TCS3200 color sensor with Arduino UNO. TCS3200 is a color sensor which can detect any number of colors with right programming. TCS3200 contains RGB (Red Green Blue) arrays. As shown in figure on microscopic level one can see the square boxes inside the eye on sensor. These square boxes are arrays of RGB matrix. Each of these…
Home Automation has always been a hot buzzing topic to learn or to work on. It is really cool to control AC appliances wirelessly. There are lots of ways to do this and imagination is the limit. In this project we will learn the most simple and easy way to build a Wireless Home Automation Project in which we can toggle AC loads by using 433 MHz RF transmitter and receiver…
