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.
Health monitoring is the major problem in today’s world. Due to lack of proper health monitoring, patient suffer from serious health issues. There are lots of IoT devices now days to monitor the health of patient over internet. Health experts are also taking advantage of these smart devices to keep an eye on their patients. With tons of new healthcare technology start-ups,…
Thermal printer is often referred as receipt printer. It is widely used in restaurants, ATM, shops and many other places where receipts or bill is required. It is a cost-effective solution and very handy to use from the user’s side as well as from the developer’s side. A thermal printer uses a special printing process which uses thermochromic paper or thermal paper for…
Raspberry Pi is a Palm Size computer that comes in very handy when prototyping stuff that requires high computational power. It is being extensively used for IOT hardware development and robotics application and much more memory hunger applications. In most of the projects involving the Pi it would be extremely useful if the Pi had a display through which we can monitor the…
Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words…
Stepper motor is brushless DC motor, which can be rotated in small angles, these angles are called steps. Generally stepper motor use 200 steps to complete 360 degree rotation, means its rotate 1.8 degree per step. Stepper motor is used in many devices which needs precise rotational movement like robots, antennas, hard drives etc. We can rotate stepper motor to any…
Minecraft is one of the most popular game in the world and people are getting additive for this interesting game. You can setup your own Minecraft server and can create your own worlds in the game. For this, you don’t need to spend money on a dedicated PC, it can be easily done with a small, credit card-sized Linux computer Raspberry Pi. If you want to play it on small LAN…
Finger Print Sensor, which we used to see in Sci-Fi movies a few years back, is now become very common to verify the identity of a person for various purposes. In present time we can see fingerprint-based systems everywhere in our daily life like for attendance in offices, employee verification in banks, for cash withdrawal or deposits in ATMs, for identity verification…
Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure speed, but using an IR sensor is easy because IR sensor module is very common device…
RFID stands for Radio Frequency Identification. RFID module can read or write small amount of data into a Passive RFID tag, which can be used in identification process in various systems like Attendance system, security system, voting system etc. RFID is very convenient and easy technology.
To read the Passive RFID cards and tag, we need a…
All embedded lovers are familiar with multimeter which a great tool to measure voltage, current, resistance etc. A multimeter can measure them easily. But sometimes we need to measure inductance and capacitance which is not possible with a normal multimeter. There are some special multimeters that can measure inductance and capacitance but they are costly. We already built…
In today’s world Bluetooth has become very popular and almost every device like mobile phone, laptop, and cars infotainment system uses Bluetooth for wireless communication. Bluetooth is not only used to transfer data but also to control another Bluetooth devices wirelessly, like using Bluetooth headset you can hear the song wirelessly from your mobile phone or can use car…
In previous article we have seen about ADC conversion using STM32. In this tutorial, we will learn about PWM (Pulse Width Modulation) in STM32 and how can we control brightness of LED or speed of DC fan using PWM technique.
We know that there are two types of signal: Analog and Digital. Analog signals have voltages like (3V, 1V...etc) and digital…
