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 our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has only two wires while SPI uses four, and I2C can have Multiple masters and slaves, while SPI can have only one master and multiple slaves. So there are more than one…
Home Automation has always been inspiring projects for most of us. Toggling an AC load from the comfort of our chairs or bed of any room without reaching for the switch in another room sounds cool doesn’t it!!. And now in the era of IoT, thanks to the ESP8266 module which made it easy to control anything from anywhere in the world.
In this…
A Microcontroller uses many different protocols to communicate with various sensors and modules. There are many different types of communication protocols for wireless and wired communication, and the most commonly used communication technique is Serial Communication. Serial communication is the process of sending data one bit at a time, sequentially…
Anyone who is interested in learning about computers and electronics will definitely love experimenting with a small and powerful platform “Raspberry Pi”. The only problem is that it doesn’t have a monitor and keyboard-mouse. This is actually isn’t a problem though, because there is a way to setup and work on the Pi without connecting it to a monitor and…
In our previous tutorial, we have interfaced stepper motor with ARM7-LPC2148. In this tutorial, we will control Servo Motor with ARM7-LPC2148. Servo motor has low power consumption advantage over stepper motor. A servo motor stops its power consumption when the desired position is reached but the stepper motor continuous to consume power to lock up the shaft in desired…
Most of us would be familiar with the 16×2 Dot matrix LCD display that is used in many projects to display some information to the user. But these LCD displays have a lot of limitation in what they can do. In this tutorial, we will use OLED to display some basic information from the Android smartphone like Time, date, network strength and battery status…
As we know microcontrollers take analog input from analog sensors and use ADC (Analog to Digital converter) to process those signals. But what if a microcontroller want to produce an analog signal to control analog operated devices like a Servo motor, DC motor etc? Microcontrollers don’t produce output voltage like 1V, 5V instead they use a technique called PWM for operating…
Every Engineer who loves to tinker with electronics at some point of time would want to have their own lab set-up. A Multimeter, Clamp meter, Oscilloscope, LCR Meter, Function Generator, Dual mode power supply and an Auto transformer are the bare minimum equipments for a decent lab set-up. While all of these can be purchased, we can also easily built few on our own like the…
In today’s automation world stepper motor and servo motor are two most commonly used motors in embedded systems. Both are used in various automation machines like robotic arms, CNC machine, cameras etc. In this tutorial we will see how to interface Stepper Motor with ARM7-LPC2148 and how to control speed of it. If you are new to ARM7 then start by learning about ARM7-LPC2148…
Bluetooth is the simplest and most popular protocol for short range wireless communication in embedded systems. Bluetooth is not only used for transferring the data from one device to another but also used to control the devices wirelessly. Almost every electronic gadget has Bluetooth support now days so it is wise choice to have Bluetooth control option in your embedded…
In electronics world there are many varieties of analog sensors in the market that are used to measure temperature, speed, displacement, pressure etc. Analog sensors are used to produce output that are continuously changing over the time. These signals from analog sensors tend to be very small in value from a few micro-volts (uV) to several milli-volts (mV), so some form of…
We all know that, Atmega328 IC is used in Arduino UNO board. This IC is the brain of the Arduino board. Actually, Arduino designers wanted to make a handy prototyping board for the beginners so they organized all the components in such way that anybody can access all the pins of the Atmega328 IC and can program it just by connecting it to computer. Arduino board is very…
