Design and build a Raspberry Pi 18650 Li-ion Battery HAT to make your projects portable We have been using Raspberry Pi for a long time to create many exciting projects. But, oftentimes we face an issue in selecting the best power source for our projects, and sometimes when the power goes off, our raspberry pi turns off abruptly which might corrupt the OS or in the worst-case damage the board itself. So, today we are building our own Raspberry Pi Zero HAT… |

Relaxation Oscillator using Op-amp An operational amplifier is an integral part of Electronics, and we previously learned about Op-amps in various op-amp-based circuits and also built many oscillator circuits using op-amps and other electronics components. An oscillator generally refers to the circuit which produces periodic and repetitive output, like a sine wave or square wave… |

Designing OR Gate using Transistor As many of us know an Integrated Circuit or IC is a combination of many small circuits in a small package which together performs a task. Like an Operational Amplifier or 555 Timer IC is built by a combination of many Transistors, Flip-Flops, Logic Gates and other combinational digital circuits. Similarly a Flip-Flop can be built by using a combination of Logic Gates and the… |

Designing an AND Gate using Transistors As many of us know, an Integrated Circuit or IC is a combination of many small circuits in a small package which together perform a common task. An Operational Amplifier or 555 Timer IC is built by a combination of many Transistors, Flip-Flops, Logic Gates and other combinational digital circuits. Similarly, a Flip-Flop can be built by using a combination of Logic Gates and… |

Frequency Compensation of Op-amp and why it is important in your Op-Amp Circuits Operational Amplifiers or Op-Amps are considered the workhorse of Analog Electronic Designs. Back from the Analog computers era, Op-Amps have been used for mathematical operations with analog voltages, hence the name operational amplifier. To date, Op-Amps are extensively used for voltage comparison, differentiation, integration, summation and many other things. Needless to… |

Thyristor Commutation Techniques To turn on a Thyristor, there are various triggering methods in which a trigger pulse is applied at its Gate terminal. Similarly, there are various techniques to turn off a Thyristor; these techniques are called Thyristor Commutation Techniques. It can be done by bringing the Thyristor back into the forward blocking state from the forward conduction state. To bring the… |

Lead Acid Battery: Working, Construction and Charging/Discharging Almost every portable and handheld device consists of a battery. The battery is a storage device where energy is stored to provide power whenever needed. There are different types of batteries available in this modern electronics world, among them Lead Acid battery is commonly used for high power supply. Usually Lead Acid batteries are bigger in size with hard and heavy… |

Passive High Pass Filter Previously, we discussed the Passive Low Pass Filter; now it is time to look into the passive high pass filter. A passive high pass filter is an electronic circuit that allows high-frequency signals to pass while blocking low frequencies below a predetermined cutoff point. Same as before, if you look into the name, it shows “Passive”, “High… |

Arduino Relay Control Tutorial 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. … |

Simple Smoke Detector Alarm Circuit Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are important safety parameters. In this project, we are going to build a Simple Smoke Detector Circuit without using any Microcontroller. This circuit triggers the Buzzer whenever it detects Smoke or fire nearby. This circuit mainly uses the MQ6 Smoke/Gas sensor to… |

Arduino Weight Measurement using Load Cell and HX711 Module Today, we are going to build an Arduino weight machine by interfacing a Load Cell and an HX711 Weight Sensor with Arduino. We have seen weight machines at many shops, where the machine displays the weight just by placing an item on the weighing platform. So here we are building the same weighing machine by using Arduino and Load cells, having a capacity of measuring up to… |

IoT based Air Pollution Monitoring System using Arduino In this project, we are going to make an IoT Based Air Pollution Monitoring System in which we will monitor the Air Quality over a webserver using internet and will trigger a alarm when the air quality goes down beyond a certain level, meaning when there are sufficient amount of harmful gases are present in the air like CO2, smoke, alcohol, benzene and NH3. It will display… |
