Coronavirus is the biggest health crisis in the history of humanity and the fight with it continues as new emerging variants like Omicron are at the brink of spreading, Moreover, according to a study conducted by a university in Japan, wearing a mask can only reduce 30% of the risk of getting Covid! Therefore, dealing with such a problem permanently on a…
Ever wondered if your everyday Arduino boards were just not enough for your tasks, and a Raspberry Pi (RPi) seemed to be overkill? Have you wished for something that was between the two, having more hardware resources and capabilities than your typical microcontroller, but being low power and efficient enough to last for days, unlike a micro-computer like RPi? Sony has a…
Thousands of lives are being lost every year due to IEDs (improvise explosive devices). IEDs were responsible for approximately 63% of coalition deaths in Iraq. An IED consists of a switch (activator), an initiator (fuse), container (body), charge (explosive), and a power source (battery) or manual ignition. Not every IED…
Artificial Intelligence (AI) is changing science fiction into reality and this technology is taking over the world. Inspired by Iron man and Jarvis we decided to build something similar which can be controlled just by hand gestures. This system detects the hand and identifies the gesture with the help of artificial intelligence and based on that, it…
In this tutorial we are going to make a Touch Capacitive PCB using an ATMega328P IC to control neo pixel led strip. We will include some features such as music reactive mode, random animation mode, and RGB controlling mode on our PCB. So far, we've made a touch capacitive piano where you can find the basics of touch capacitive technology. And now in this…
As Christmas is around the corner and the essence of it is incomplete without the decoration and the Christmas tree. So, instead of using the same old Christmas tree ornaments that we put up every year, let's step it up a notch and use Arduino with Neo pixel LED Strip, JQ6500 Voice Module, and PIR Sensor. The PIR sensor is used to detect movement, the…
Vending machines are very popular nowadays due to their ease of use, multiple use cases, and no human intervention. It can dispense products such as beverages, tickets, snacks, etc. by inserting currency coins. Vending machines appear in public and private areas such as malls, markets, offices, etc. for various applications. In this project, we are going to build a Portable…
There are lots of people working with renewable energy, especially Solar Power. However, the instruments required to properly predict the solar condition or how much power can be received from the sun in a given place is a crucial thing for successful Solar Operations. It is very useful to predict how much energy can be generated in a place and where to put the solar panel.…
In this article we decided to make a PID Controller based Heater that can be used to control the temperature of the hot end of the 3D printer or by slightly modifying the device it can control the temperature of a DC Soldering Iron very efficiently, and a little more tweak and you can control a TRIAC and that can control the RPM of an AC motor or an…
Humidifier is a device used to increase the relative humidity of a closed area to ensure enough moisture in the area. Especially during winters, when the heater is turned on, it causes the relative humidity of the air to decrease. In this diy project, we are going to build an automatic humidifier, which can maintain the relative humidity of the atmospheric air by using…
Every one of us likes a little greenery in our houses, don’t we? Plants require really low maintenance and can be left for days without supervision, but our long trips extending over a week or 2 can be detrimental to the health of plants due to the lack of moisture in the soil. In such situations, the plant may wither or die due to the absence of proper watering. In order to…
Most musical concerts nowadays are accompanied by some fancy light shows. Almost all concerts, festivals, and nightclubs have a visual show or effects to match. So, why not build your own music visualizer that reacts to the music or audio? Here's a simple yet effective project to make your very own music/audio visualizer using Arduino Nano, 32x8 Dot Matrix Display…
