How to use a Relay with Arduino Uno

Wouldn’t it be great if you could operate your switch without physically toggling it on and off?  Well, relays are one of the best ways of doing this. A relay is a switch, controlled by an electromagnetically charged coil. When the coil charges up, it toggles the switch into its open or closed position. If you wish to control your

How to store Data using ATMEGA328 EEPROM

So far everything you do on an Arduino is lost as soon as power is disconnected. The question is how do you go about storing information so that it isn’t lost after a reset. The answer is EEPROM. EEPROM is a form of solid-state non-volatile memory which is commonly used in systems to store small amounts of data for microcontrollers.

How to Use Interrupts with Arduino

Interrupts is a very useful feature of Arduino. They let you respond to external events, while doing something else. It is a section of hardware on the microcontroller which is capable of monitoring the state of an input pin by itself and can literally interrupt the microcontroller in whatever it’s doing. The beauty of this is that the interrupts are

How to Avoid Hard Coding on ESP8266 with WifiManager Library

If your sketches have the credentials hard-coded in and if you get a new router or want to bring your device to a different Wi-Fi network you’re going to need to reprogram it. The need of reprogramming will make your sketches less shareable. You’ll probably want to replace your credentials with placeholders before you upload it anywhere and anybody using

How to use ESP8266 Wifi Modes: Station and Access Point

ESP8266 works in two modes: Station (STA) and Access Point (AP).  In short, AP mode allows it to create its own network and have other devices (your phone) connect to it and STA mode allows the ESP8266 to connect to a Wi-Fi network (one created by your wireless router). So, an important feature about the ESP8266 is that it can

How to Install Libraries written for the Arduino IDE

Arduino library is just a group of functions that are packaged together that are similar. They are a collection of codes that extend a programming language.  Libraries make it easy for programmable devices such as microcontrollers, SoCs, etc., to communicate with sensors, displays, modules, etc.  Some of them, such as the SoftwareSerial library, are packaged with the IDE and are
