Hey guys welcome back to the Techatronic. So today we are making a project which can be used at many places the project name is LED VU Meter using Arduino . In this project we are going to use Some LEDs. All we know how to work LED view metre and where it is used we have seen this view metre in tape recorder videos music system TVS and many other devices which is associated with the music so today we are going to make the same view metre which will be react with the music or sound. LED VU Meter Introduction. An LED VU meter is a device or we can say a circuit used to visually display the level ..read more

In the realm of hobbyist electronics, the fusion of sound and microcontrollers has always been an intriguing avenue for exploration. With the advent of compact and versatile modules like the DFPlayer Mini, Arduino enthusiasts have been empowered to integrate sound seamlessly into their projects using df player mini with Arduino, whether it’s a musical greeting card, a sound effects generator, or even a mini jukebox. In this article, we’ll delve into the DFPlayer Mini, understand its capabilities, and explore how to integrate it with Arduino to create exciting audio projects. DFPlayer Mini The ..read more

Automatic school Bell project is very useful project which can be use in school as well as in college. Hey guys, welcome back to the techatronic. this time we made a good project. As all we know how the school and college bell work. there is a person who rings the bell when required. when a particular subject period over and the next subject period started.What if there were a microcontroller which controls the automatic school bell which rings itself according to a timetable. This project is the implementation of same functionality. The automatic school bell has a feature where you need to e ..read more

Hey guy, welcome back to Techatronic, there is many applications where we need to DC motor direction control for example in washing machine we need both direction anti clock wise and clockwise. When we control the DC motor direction manually,once clockwise then anti clockwise. Required the DPDT switch. in many Application we need to control the DC motor direction automatically. I made one project there is statue connected with the motor and the statue move left and right where we were using the dc motor. the dc motor rotate clockwise then after 10 seconds the motor will rotate anticlockwire. s ..read more

In this Modern Time, all we know is that everything is modern and techy. we see many things in our homes too like an automatic water pump system or Stair lights. If you buy these automatic stair light it will expensive and tough to install. So, we have decided to make our own automatic stair lights project. install this project in our home. Here we will explain in detail how to make automatic stair lights project using sensor and controller. here we will use two proximity IR sensor and Arduino microcontroller to make this project. this is also known motion sensor stair light. because it contr ..read more

Hey guys, welcome back to the Techatronic. Today we are going to make an Air Quality monitoring system project with the help of Arduino. In this, we will use many sensor to measure the air quality index. many a time you have seen the AQI Reading at many places. This project is all about Air quality. if you travel from one place to another places you can check the air quality near by you by the help of this device. That’s why we are doing an air quality check project. We are going to use multiple sensors to measure the air quality using Arduino. By using various sensors Mq series sensor and DH ..read more

There is a lot of seven-segment display in the market and it’s widely used into the electronics as well as in electrical product. we saw this module many time nearby appliances like radio, weighing machine , counters and many other places. So, for now we are making a tutorial on how to use TM1637 with Arduino. here in this article I will share all the things code , circuit and step by step instruction for the same. 4-digit seven-segment display can show the 4 digits simultaneously by writing a small code. not need to write the raw code there are many libraries available that help to program t ..read more

Hey geeks welcome back to the techatronic. This time we have made this great project which is NRF Remote control for Rc car. This remote control can control any of the cars. there is one more device which need to be install in the car or the other device which will control by the remote. the remote control have one transceiver and one controller which manage the remote. Introduction This RC remote control is made by the NRF24L01 module which is responsible for wireless communication which you can see in the images. This remote will be paired with the receiver device automatically. and when you ..read more

Hey guys, welcome back to Techatronic. Today we will make an smart water heater project using Arduino and DS1820B temperature sensors. if you want to make a portable smart water heater for winter you can make this. this can be used in many things where we need a small , smart and safe water heater they can make this smart water heater. Introduction this is a very simple and useful project which can be used at many places. like if you are going anywhere you can carry it with you. these smart water heater are available in the market but this is unique and have some extra feature. so, if you want ..read more

Hey guys , welcome back to the Techatronic. Smart helmet has many features like Navigation, Call , accident detection , alcohol detection and many more feature to make this helmet as a smart helmet. As we consider the safety and security of the driver this helmet can help a lot. such as if you are drunk you can’t start the bike. so, it is reloaded with the lots of features. the main aim to make this smart helmet project to the safety of the driver. This helmet is made up of many electronic components such as GPS, GSM, and other sensors. also, we required a working 2G, 3G sim for gsm module. w ..read more
