LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will use an AC bulb instead of a normal LED and will blink an AC bulb. You can also drive into this project of Relay Interfacing with PIC Microcontroller.

A timer is a type of clock used for the measurement of time intervals. There are two types of timer, one which counts upwards from zero, for the measurement of the elapsed time, called as Stopwatch. And, the second one counts down from a specified time duration provided by the user, generally called as Countdown Timer.

Here, in this tutorial we will…

In this tutorial, we are making a Digital Thermometer using PIC microcontroller and LM35 Temperature Sensor. In this project, we will sense the temperature using LM35 and display it on 16x2 LCD. LM35 Temperature Sensor is accurate and cheaper and doesn’t require any external calibration. The output voltage is proportional to Celsius temperature scale and changes by 10mV…

The digital Revolution started in 1950 changes all the existing mechanical and analog electronic structures into digital computers. Since the growth of digital electronics has been exponential, today it is almost impossible for a person to resist using any electronic equipment. Starting from the alarm clock that wakes you up and the toaster that serves you breakfast,…

This tutorial will help you to send an SMS to any registered mobile number from ESP8266. The ESP8266 is a powerful Wifi module that has been dominating the world of IOT projects. This is a Microcontroller independent tutorial meaning; you do not need any UC/UP like Arduino or PIC. We will directly program the ESP8266 module using the Arduino IDE. Once it is programmed we can…

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,…

Bluetooth modules like HC-05 and HC-06 are easy to set-up and quick to use with Arduino IDE, but they have their own limitation like high power consumption and they operate on the old Bluetooth V2.0. Also, recently I got myself a new ESP32 DEV kit, these modules has a punch of features like in-built Wi-Fi and Bluetooth, ample ADC and DAC pins, Audio Support, SD Card Support…

As the name suggest 555 timer is basically a “Timer”, which create an oscillating pulse. It means for some time output pin 3 is HIGH and for some time it remains LOW, that will create a oscillating output. We can use this property of 555 timer to create various timer circuits like 1 minute timer circuit, 5 minute timer circuit, 10 minute timer circuit, 15 minute timer…

This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time. There are two important components in this circuit, first is PIR Sensor (Passive Infrared Sensor) and second is Relay.

PIR Sensor

Mobile phones generally charge with 5v regulated DC supply, so basically we are going to build a 5v regulated DC supply from 220 AC. This DC supply can be used to charge mobiles as well as the power source for digital circuits, breadboard circuits, ICs, microcontrollers etc.

You can also build 6V DC, 9V, 12V,…

In this tutorial we are going to interface a 4x4 (16 key) keypad with ARDUINO UNO. We all know keypad is one of the most important input devices used in electronics engineering. Keypad is the easiest and the cheapest way to give commands or instructions to an electronic system. Whenever a key is pressed in keypad module the Arduino Uno detects it and shoes the…

After developing few popular robotic projects like line follower robot, edge avoiding robot, DTMF robot, gesture controlled robot, etc. in this project we are going to develop a bluetooth controlled robo car. Here we used a Bluetooth module to control the car, and it is also an android based application.
