Thermometers are useful apparatus that have been used for a long time for temperature measurement. In this project, we have made an Arduino based digital thermometer to display the current ambient temperature on a 16x2 LCD unit in real time. It can be deployed in houses, offices, industries, etc., to measure the temperature. We can divide this Arduino…

The ESP32 is a powerful, low-cost microcontroller that is widely used in the development of IoT projects. It is popular for its high processing power, low energy consumption, and built-in Wi-Fi and Bluetooth capabilities.

Bluetooth Classic is a wireless communication protocol that is used for connecting devices over short distances.…

Measuring the voltage and current will always be helpful while making or debugging any electrical system. In this project we are going to make our own Digital Ammeter using PIC16F877A Microcontroller and current sensor ACS712-5A. This project can measure both AC and DC current with a range of 0-30A with an accuracy of 0.3A. With few modifications on the code you can also use…

In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors and resistors to build it. The lighting system built in this way is not only efficient but cost effective but it can also create stunning color effects that can transform…

In this RFID based Attendance System project, we will explain you how can we count attendance automatically by using RFID cards. RFID Technology (Radio Frequency Identification and Detection) is commonly used in schools, colleges, office and stations for various purposes to automatically keep a track of people.  Here we will count the attendance of an authorized…

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…

Bistable Multivibrator mode of 555 timer IC is the easiest mode of 555 timer IC, where Monostable multibrator mode has one stable & one unstable state, Astable multvibrator mode has both the unstable states, here in Bistable mode, both the states are stable. Means it remains in the same state (either HIGH or LOW) until an external trigger is applied; otherwise it stays…

LEDs are commonly used in electronic circuits as they consume less power, are easy to use, and have a long lifespan. In this tutorial, we will learn how to build an LED ON and OFF circuit using 555 timer IC and BC557.

Before we get started, let's understand the components we will be using in this circuit.

Most heart diseases are associated with and reflected by the sound that the heart produces, and one of the easiest and cheapest ways of diagnosing cardiac dysfunction is by Heart auscultation i.e listening to the heart sound. Now if we are talking about traditional auscultation, that requires experience and good listening skills. That is why in this project we…

You have seen Automatic Wiper System in luxury cars where Windshield Wiper automatically gets activated when there is Rain or if there is some water on the windshield. Electronic Wiper is very common device that is attached in every car to wipe the water on the windshield during the rain. But generally they are manually operated and we need to switch them ON manually. But…

Hello friends, I am Chirukesh, and I am a YouTuber, this is a Pulse Oximeter that measures Oxygen Saturation blood also measures HeartBeat rate just using your finger. During this corona pandemic, a pulse Oximeter is very essential to measure heartbeat and oxygen levels. Friends you can also check with the medical PULSE OXIMETER, the reading will…

In this article, let us discuss how to interface WIFI module ESP8266 with a PIC microcontroller. So far you might have been using the ESP8266 module as a standalone microcontroller or might have been using it with the Arduino library. But, when it comes to hardcore embedded system projects we should know how to use it with PIC microcontrollers as well. This will help…
