The installation and use of outdoor security cameras have never been easier with advanced technologies that are currently in use. You can easily install a security camera now without calling an expert because we now have wireless cameras. The 4G Solar Security Cameras do not only work using the 4G network, but they also get […]
In this tutorial, I will guide you step by step on how to create and fabricate a 5x5x5 LED cube using Arduino Mega. This tutorial will also cover all the fundamentals required to make a 5x5x5 LED cube, like how to create a 3D arrangement using LEDs, how to create different animations and patterns, working
In this tutorial, you will learn how to upload a bootloader in a newly purchased ATmega328P IC, and upload code in ATmega328P, ATtiny85, and ATmega8 using Arduino UNO board.In some Arduino projects, you may only want to use the microcontroller IC(ATmega328P) instead of using the whole Arduino UNO board. In that case either you can
About the power bank circuit In this project, we will be making a power bank using a pre-built power bank circuit and 18650 Li-ion cells. This power bank circuit has an onboard LCD that will show you the total charge remaining, input-output voltages, and current. It has two USB ports for charging your mobile phone.
What is an OLED display? The Organic Light Emitting Diode(OLED) display or also known as Organic EL Diode display is a type of display that is based on an organic compound that emits light in response to the electric current applied to it. It is a self-light emitting display that does not require a backlight
In this tutorial you will learn, how to convert your electronic circuit into a professional PCB and get it printed from an online PCB manufacturer.If you are an electronic hobbyist or an engineering student, you must have designed an electronic circuit using a general purpose PCB and have faced lots of problems. Like, wiring, mishandling
About GSM Module The GSM module that we are going to use here is SIM800L. It is compact and highly efficient as compared to other GSM modules. This type of module is used when you want to work on a cellular network using an Arduino. The SIM800L supports quadband frequencies of 850/900/1800/1900MH. By using this
What is ADC? ADC stands for Analog to Digital Converter. ADC is used for converting the analog input voltage to its digital form. It is necessary for every microcontroller to have ADC in it, as all the microcontrollers work only on digital input and output voltages. So, ADC takes analog voltages and converts them into
About NodeMCU NodeMCU stands for Node Microcontroller Unit. It is an open-source Lua-based firmware that is designed for IoT(Internet of Things) applications. The module that runs this firmware is ESP-12E and that module is based on 32-bit ESP8266 MCU. It has 2.4 GHz Wi-Fi that supports WPA/WP2. The ESP-12E comes with a programmer and a
About this project This project is all about how to create an automatic hand sanitizer using an Ultrasonic sensor and Arduino. You have already seen a lot many hand sanitizers based on IR sensors, and those hand sanitizers are really simple and easy to make. But those sanitizers are not efficient and accurate as hand
What is an RGB LED? The RGB LED is a type of LED that can produce three main colors that are RED, GREEN, and BLUE. In other words, it’s a single LED that contains three LEDs inside it. One for the RED color, one for the GREEN color, and one for the BLUE color. The
What is a Blue Pill board? Unlike, the famous Arduino UNO board, the Blue Pill is a high-performance ARM Cortex-M3 32-bit microcontroller development board that works at a maximum operating frequency of 72MHz. As you already know that Arduino UNO board has some limitations when it comes to more complex projects because of its limited
In this article, we are going to see how to interface the GSM Module with Arduino. There are different kinds of GSM modules available on the market. We are using the most popular module based on Simcom SIM900 and Arduino Uno for this tutorial. Interfacing a GSM module to Arduino is pretty simple. You only
A Full-wave rectifier is a circuit arrangement that makes use of both half cycles of input alternating current (AC) and converts them to direct current (DC). In our tutorial on Half-wave rectifiers, we have seen that a half-wave rectifier makes use of only one-half cycle of the input alternating current. Thus a full-wave rectifier is
