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.
In the previous tutorial, we have made RTC clock using DS3231 and ESP32. To minimize hardware requirements we will make Internet clock without using RTC module. This is more accurate as compare to RTC clock. ESP32 is a Wi-Fi module and can be easily connected to the internet so we will use NTP (Network Time Protocol) and UDP (User Datagram Protocol) to fetch Time from the…
There are possibilities in embedded design where you do not have enough I/O pins available in your microcontroller. That can be due to any reason, may be your application needs multiple LEDs or you want to use multiple 7-segment displays, but you don’t have required I/O pins in your microcontroller. Here comes a perfect component, shift register. Shift register accepts…
Display is the necessary part of any machine whether it is any home appliance or industrial machines. Display not only shows the control options to operate the machine but also shows the status and output of the task performed by that machine. There are many types of displays used in electronics like 7-segment display, 16x2 LCD display, TFT touch screen display, OLED display…
Raspberry Pi has always been the first choice for developing IoT based applications if some level of computation is involved. With the flexibility of python and strong developer community it is very easy to collect, log, analyze or report a set of data using the Pi. In this tutorial we will learn how to blend in the power of Raspberry Pi with the Amazon AWS service to…
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. Learning how to use TI Microcontrollers would definitely be a mighty tool up in our…
In this project we will interface a Relay with PIC Microcontroller PIC16F877A. Relay is a mechanical device to control high voltage, high current appliances ‘ON’ or ‘OFF’ from lower voltage levels. Relay provides isolation between two voltage levels and it is generally use to control AC appliances. From mechanical to Solid state relays, there are various type of relays…
In this tutorial we will learn about Servo Motor and How to interface Servo with 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…
Be it the long stretched highways or your doctors front door, we have sign boards placed everywhere to provide us information. But these sign boards are often boring and cannot be configured as per our interest from time to time. So in this project we are going to build a Bluetooth controlled Sign board using an 8*8 Matrix display. A unique feature of this project is its…
In this tutorial, we will learn about Real Time Clock (RTC) and its interfacing with the ESP32 and OLED display.
We will use the DS3231 RTC module to keep track of the correct time and display it on the SPI OLED by using ESP32 as our microcontroller. ESP32 is more than a microcontroller. It has a Wi-Fi and Bluetooth chip inside it and 39 GPIO pins.…
You have seen RFID Door Lock Mechanism in some Hotels and other places, where you don’t need a key to unlock the room. You are given a card and you just need to put it in front of a RFID Reader box, and the lock gets unlocked with a Beep and a Blink of LED. This RFID Door Lock can be made easily at your home and you can install it in any door. These Door lock is…
Temperature and Humidity are the most common parameters that are being monitored in any environment. There are tons of sensors to choose from for measuring temperature and humidity, but the most used one is the DHT11 due to its decent measuring range and accuracy. It also works with one pin communication and hence is very easy to interface with Microcontrollers or…
“Be a bright spark, lights off till it’s dark!” sometimes we forget to turn off the lights and waste electricity and you must have also seen street light turned on in the day. We have already built few circuits on Dark detector where lights turn off automatically if it is bright outside and turns ON if it is dark outside. But this time, in this circuit we are not only…
