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.
Digital wall Clocks are getting more popular now days and they are better than analog clock as it provides accurate time in hours, minutes and seconds and its easy to read the values. Some digital clocks also have many facilities like displaying temperature, humidity, setting multiple alarms etc. Most of the digital clocks use seven segment display.

In some applications, user input is required to control the functions of a device. There are different kinds of user input methods used in the embedded and digital electronics. The touch sensor is one of them. Touch sensor is an important and widely used input device to interface with a microcontroller and it has made inputting data simpler. There are individual places where…
Making wireless projects in embedded electronics becomes very important and helpful as there are no jumbled wires all over which makes the device more handy and portable. There are various wireless technologies such as Bluetooth, WiFi, 433 MHz RF (Radio Frequency) etc. Every technology has its own advantages and disadvantages such as cost, distance or range transfer, speed…
Digital and Analog is an integral part of Electronics. Most of the devices have both ADC as well as DAC and they are used when there is a need of converting signals either from analog to digital or digital to analog. Also the real world signals like sound and light are analog in the nature, so whenever these real world signals have to be used, the digital signals have to be…
In modern electronics world, touch input is used almost everywhere, whether it can be a mobile phone or an LCD monitor switch. Capacitive touch is the widely used in the touch sensor segment and we previously used capacitive touch with a Raspberry Pi. Here in this project, we will interface touch sensor with 8051 microcontroller AT89S52. If you are new to 8051 microcontoller…
The OV7670 camera module with Arduino programming has always dominated the electronics industry, as it has lots of applications, such as visitor monitoring systems, surveillance systems, attendance systems, etc. The OV7670 camera module with Arduino that we use today is smart and has a lot of features that were not present in earlier cameras. This comprehensive…
GSM Modules are frequently used in IoT projects since it has the ability to send and receive data remotely. The GSM Modules doesn’t have much dependencies like the Wi-Fi modules. While other wireless modules such Wi-Fi or Zigbee have cons such as short range and cost, the GSM Module have the reliability, long range Since only one SIM card is required with valid plan. Though…
In previous tutorial we interfaced the XBee module with Arduino Uno and made them communicate wirelessly using XBee module. Now we will interface XBee module with Raspberry Pi which will act as a receiver and make it communicate wirelessly with another XBee module (XBee explorer board) which is serially connected with the laptop.

Face Recognition is getting increasingly popular and most of us are already using it without even realizing it. Be it a simple Facebook Tag suggestion or Snapchat Filter or an advanced airport security surveillance, Face Recognition has already worked its magic in it. China has started using Face Recognition in schools to monitor student’s attendance and behaviors. Retail…
In this age of IoT (Internet of Things) where everything can be controlled remotely using your smartphone, why to carry keys with you. There are lots of technologies to support wireless controlling of devices like RFID, Bluetooth, Wi-Fi, LoRa. We previously built some door alarms and door controlling circuit to open and close the door wirelessly:
Arduino RFID Door Lock…
DC motors are the most widely used motors. These motors can be found almost everywhere from small projects to advanced robotics. We previously interfaced DC Motor with many other microcontrollers like Arduino, Raspberry pi and used it in many robotic projects. Today we learn to control DC motor with AVR Microcontroller Atmega16. But before going ahead let’s know more about…
Microcontrollers work only with digital values but in real world we have to deal with Analog signals. That’s why ADC (Analog to Digital Converters) is there to convert real world Analog values into Digital form so that microcontrollers can process the signals. But what if we need Analog signals from digital values, so here comes the DAC (Digital to Analog…
