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.
A color sensor is a simple, and easy-to-use device that can be used to identify the color of an object and after detecting the color, appropriate action can be triggered. This type of sensor provides easy solutions for sorting and packaging in an industrial environment while expensive sensors are used in industries, the economical ones such as TCS3200 can be used for…
In one of our basic projects, we have shown you how you can interface a MAX30102 Pulse Oximeter and Heart Rates Sensor With Arduino, but one of the major problems with that sensor is its inconsistency, and lack of support for Arduino IDE which is why in this article we thought to use a simple pulse sensor to measure the heartbeat. This pulse sensor is a well-designed…
Sensors now play an essential role in the safety and security of a wide range of flats, houses, and businesses by detecting smoke, fire, or gas and alerting the appropriate person. Today's post will discuss one such Sensor, the MQ-3. The MQ-3 is Alcohol Sensitive Sensor that is often used in a breath analyzer. So, let's jump right into it.
MQ-3 Alcohol Sensor…
I know making a clock sounds a little irrelevant, especially nowadays because we all have smartphones and no one is going to use or look into the clock for time, but it is good when you are doing some work or during the workout. So, I decided to make one Arduino digital clock for my room. While searching for the clock model, I got thousands of designs but most of them were…
Thermistors are simple, inexpensive, and accurate components that make it easy to get temperature data for your projects. Thermistors or THERMally sensitive resISTORs are variable resistors, whose resistance will be changed with the temperature. This feature enables us to read the temperature or change in temperature by…
In today's digital world, electronic circuits play an important role in the devices that we use daily. All the Integrated Circuits ranging from basic IC’s (OR gate, AND gate, NOT gate, Flip Flops, Latches, Counters, ALU’s) to complex circuits like Microprocessor, FPGA, Microcontrollers, SOC, Motherboards are designed by combining billions and billions of transistors in…
Ever felt lazy in getting up from the comfort of your bed to turn off that light switch. So here we have a cost-effective DIY project to turn any traditional switch into a smart switch. This project doesn't require you to change switches in your AC switchboards. As the brain of the project, we will be using ESP8266-01, a solid-state relay for safe and efficient AC…
In many of our previous articles, we have used many different types of temperature and humidity sensors like DHT22, DHT11, DS18b20, and LM35 to measure environmental parameters. In every one of those articles, the one thing in common is that none of those sensors measure barometric pressure. So in today's article, we wanted to interface the BMP280 with an Arduino and measure…
In one of our previous tutorials, we have shown you how you can interface LM35 Temperature Sensor with Arduino because it's cheap, easy to use, and requires minuscule power for stable operation. But one of the major disadvantages of the LM35 sensor is that it is analog in nature, so it's sensitive to external noise. There are a variety of sensors that may be used to solve…
A sound sensor is a simple, easy-to-use, and low-cost device that is used to detect sound waves traveling through the air. Not only this but it can also measure its intensity and most importantly it can convert it to an electrical signal which we can read through a microcontroller. But do you know how…
For one of our projects at circuit digest, we wanted to build a Persistence of Vision Display or POV display with WS2812B LEDs. While making the project, our only focus was on how we could make it simpler along with less hardware. As a result, we chose some simple WS2812B RGB LEDs and an ESP8266-01 as the brains for this project because they are lightweight …
We are all aware of a basic voltmeter, ammeter, and wattmeters, the three basic things you need to measure values on any electronic projects or circuits. Measuring voltage and current with the help of a multimeter can be a good way to start, but one of the biggest problems I face while testing a circuit is, measuring power efficiency. So, today we…
