Below section covers a list of simple microcontroller projects to learn and work with the concepts of various microcontrollers and architectures. These microcontroller based projects are covered with detailed explanation of working of hardware, circuit diagrams, software and codes.
Microcontrollers are widely used in various industries, electronic products, automobiles etc.. to perform computing or logical operations. With this huge importance the demand of microcontrollers in industries is prominent and hence as electronics engineers it is important for us to learn how to use them. There are a large number of semiconductor companies manufacturing a variety of microcontrollers, the most popularly ones are 8051 microcontrollers, AVR microcontrollers, PIC microcontroller, TI Microcontrollers, Arduino, Raspberry Pi etc.
GSM modules are interesting to use especially when our project requires remote access. These modules could make all actions that our normal mobile phone could do, like making/receiving a call, sending/receiving a SMS, connecting to internet using GPRS etc. You can also connect a normal microphone and speaker to this module and converse on your mobile calls. This will…
A Rotary encoder is an input device which helps the user to interact with a system. It looks more like a Radio potentiometer but it outputs a train of pulses which makes its application unique. When the knob of the Encoder is rotated it rotates in form of small steps which helps it to be used for stepper/Servo motor controlling, navigating through a sequence of menu and…
Making our projects Wireless always makes it to look cool and also extends the range in which it can be controlled. Starting from using a normal IR LED for short distance wireless control till an ESP8266 for worldwide HTTP control, there are lots of ways to control something wirelessly. In this project we learn how to build wireless projects using a 433 MHz RF module…
Building stuff and getting them work, the way we want, has always been sheer fun. While that being agreed, building stuff that could fly would defiantly pump a bit more anxiety among the hobbyists and hardware tinkerers. Yes! I am talking about Gliders, Helicopters, Planes and mainly multi-copters. Today it has become very easy to build one on your own due to the community…
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…
We all know about Electricity energy meters which are installed in everyone’s house or offices to measure the electricity consumption. At last of every month, many of us get worried about the high electricity bill and we have to look at the energy meter once in a while. But what if we can monitor our electricity uses from anywhere in the world and get an SMS/E-mail when your…
GPS stands for Global Positioning System and it is used to find out location, altitude, speed, date and time in UTC. In this project we are going to interface a GPS module with NodeMCU. A simple local web server is created using NodeMCU and the location details are updated in that server webpage. Specialty of this IoT based project is we can check the location in Goolge Maps…
In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, circuit…
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…
In this tutorial we will make a Digital Clock by interfacing RTC module DS3231 with MSP430 and display the time and date on 16x2 LCD. The MSP-EXP430G2 is a Development Tool a.k.a LaunchPad provided by the Texas Instruments to learn and practice on how to use their Microcontrollers. This board falls under the MSP430 Value Line category where we can…
In this tutorial we will Interface Stepper Motor using MSP430. The MSP-EXP430G2 is a Development Tool a.k.a LaunchPad provided by the Texas Instruments to learn and practice on how to use their Microcontrollers. This board falls under the MSP430 Value Line category where we can program all the MSP430 series Microcontrollers. If you are new to MSP then…
It’s been almost two years since amazon released the Amazon ECHO voice controlled speaker and the popularity of the speaker has continued to soar for reasons which are probably not far from the astounding performance of the Alexa voice service and the fact that the platform was opened up to developers which has led to the development of Alexa compatible devices by top…
