Power Bank Circuit on PCB The features of the digital products are growing enormously which triggers the frequent usage of smart phones in several applications. Thus the battery backup time is getting decreased. It will be fun to build a Power Bank for Mobile Phone as spare charging source for emergency purpose which is also portable. Previously we have made… |

DIY Stun Gun Circuit on PCB Stun gun is a device which generates high voltage at it’s output by taking low voltage as input. Concept of this device is based on High volt inverter. Here we are building this Stun Gun circuit on PCB. Stun Gun can be dangerous and can cause serious damage if not used properly, we take no RESPONSIBILITY for any resulting actions. This stun gun circuit can also works in… |

High/Low Voltage Detection and Protection Circuit using PIC Microcontroller We often see voltage fluctuations in electricity supply at our home, which may cause malfunction in our home AC appliances. Today we are building a low cost High and Low Voltage Protection Circuit, which will cut off the power supply to the appliances in case of High or Low voltage. It will also show a alert message on 16x2 LCD. In this project, we have used PIC… |

Earthquake Detector Alarm using Arduino An earthquake is an unpredictable natural disaster that causes damage to lives and property. It happens suddenly and we cannot stop it but we can be alerted from it. In today’s time, there are many technologies which can be used to detect the small shakes and knocks, so that we can take precautions prior to some major vibrations in earth. Here we are using Accelerometer… |

Simple Digital Voltmeter Circuit with PCB using ICL7107 In this project we are going to build a Digital Voltmeter without using any microcontroller. Here we are using a very popular IC for voltage measurement namely ICL7107/CS7107. Using ICL7107, we can build accurate and very low cost voltmeter. ICL7107 is a 3.5 digit analog to digital converter (ADC) which consumes very low power. The IC has internal circuit for driving… |

How to Design a Circuit Board (with Example PCB of Voice Modulator Circuit) In this project, we are going to make a Voice Modulator Circuit, by using self-designed PCB. In this project, we have designed a PCB using EASYEDA online PCB simulator and designer. This is a fun project, mainly designed for changing or altering the voice. Generally, when we speak in a MIC we hear same voice. But in this project when we speak in MIC, we will hear a little… |

PIC Based Car Battery Voltage Monitoring System In this project we are going to make a PIC based Car Battery Monitoring system on PCB. Here we have designed a PCB using EASYEDA online PCB simulator and designer. This Car Battery Monitoring Circuit is used to monitor the power of Car Battery by just plugging it into the power outlet on the dashboard of a car. The PCB also has the option to use it as Voltage Measurement… |

Smoke Detector using MQ2 Gas Sensor and Arduino Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million). This circuit triggers the Buzzer when Smoke level… |

Understanding Timers in PIC Microcontroller with LED Blinking Sequence This will be the fifth tutorial in our PIC Tutorial Series, which will help you to learn and use Timers in PIC16F877A. In our previous tutorials, we had started with Introduction to PIC and MPLABX IDE, then we wrote our first PIC program to blink the LED using PIC and then made a LED Blinking Sequence by using delay function in PIC Microcontroller. Now let us use the same… |

LED Blinking Sequence using PIC Microcontroller In our previous tutorial, we learnt about Blinking a LED using PIC microcontroller and built the same circuit on Perf board. Then we used PICkit 3, ICSP and MPLAB IPE for dumping the program onto our Perf board. Now, in this tutorial we will advance our self to using more pins on the PIC microcontroller. We will use 7 outputs (LEDs) and one Input. For this tutorial we will… |
