This is another interesting IOT project in which we will build a Security system which can trigger an E-mail when it detects someone. This project has blend in the power of ESP8266, PIR sensor and ISD1820 Voice module. At the end of this article you would have built a fully functional Security system which can be Armed/Disarmed (Activated/De-activated) remotely via internet…
In the measurement industry, a very crucial functional block is a Programmable Gain Amplifier (PGA). If you are an electronic enthusiast or a college student, you have probably seen a multimeter or oscilloscope measuring very small voltages very preciously because the circuit has a built-in PGA alongside a powerful ADC that helps with the precise measurement process.

Raspberry Pi is the pocket sized computer having almost all the feature of a normal computer including USB port, LAN port, audio/video output, HDMI port etc. It also has inbuilt Bluetooth and Wi-Fi connectivity which makes it perfect candidate to build various online servers like Webserver, Media server, Print Server, Plex server etc. So here we…
Sometimes people find it difficult to read temperature from analog thermometer because of fluctuations. So here we are going to build a simple Digital thermometer using 8051 microcontroller in which LM35 sensor is used for measuring the temperature. We have also used LM35 to build digital thermometer using Arduino, NodeMCU, PIC, Raspberry Pi and other microcontrollers.…
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…
One of the coolest embedded platforms like the Arduino has given makers and DIYers the ability to get location data easily using GPS module and thus build things that rely on location. With the amount of power packed by the Raspberry Pi, it certainly will be quite awesome to build GPS based projects with the same cheap GPS modules and that is the focus of this post. Today in…
In previous tutorials, we have covered the basics of FreeRTOS with Arduino and the Queue kernel object in FreeRTOS Arduino. Now, in this third FreeRTOS tutorial, we will learn more about FreeRTOS and its advance APIs, which can make you understand the multi-tasking platform more deeply.
Semaphore and Mutex (Mutual Exclusion) are the kernel objects…
In the previous tutorial, we introduced FreeRTOS in Arduino Uno and created a task for the blinking LED. Now, in this tutorial, we will dive more into advance concepts of RTOS APIs and learn about communication between different tasks. Here we also learn about Queue to transfer data from one task to another and demonstrate the working of queue APIs by interfacing 16x2 LCD…
Amplifier is an electronic circuit or device which is used for amplification purpose and used mainly in sound reproduction as well in our electronic industry widely. There are many types of amplifier available by using different components like transistor based amplifier, op-amp based amplifier, transformer based amplifier. Sometimes we use a Preamp Circuit in circuits…
As the world is heading towards automation and artificial intelligence, different innovations are taking place every day to make things smarter and scalable. Nowadays in the era of the Internet of Things, everything is connected with the internet and a number of IoT enabled boards are coming in the market. We reviewed a few boards previously like PIC IoT WG Development,…
Who does not like the rumbling tone of a distorted electric guitar? It is a key part of many important genres of music, especially in blues and rock music genres and is also frequently used in hard rock, metal or the punk music genre. In this project, we will build a basic distortion pedal for guitars using a simple circuit. You can also check out the Arduino Guitar Tuner Circuit if you are…
The LA4440 is a very popular dual-channel audio amplifier commonly used to build high power audio amplifiers. The IC is known for its high power, easy availability and cheap price which makes it popular among Home Theatre and Car Amplifier Systems which operate on 12V. Hence in this article, we will learn how to build a High-Power Stereo Audio Amplifier using the LS4440…
