Three different way of connecting a push button with an Arduino microcontroller.
Here I want to tell you how to make incremental encoder from stepper motor.
In this tutorial, I am going to talk about the PCF8574 8-bit GPIO port extender.
How to go from theory to a practical working prototype.
by Marc De Loor
Did you ever get into a situation where you had to wire up two, three or more I2C sensors to your Arduino just to realize the limitation?
After you read this post, your projects will never run out of power after a power outage.

In this project, I am going to make a LAN cable tester with just a few basic electronics components. It cost me just a bit over $3.
How about we connect an Arduino to our mobile browser, run Node-RED and Johnny-Five on the browser.

This is my 4th tutorial on how to drive a RELAY (not a relay module) with an Arduino.
You can use the reset button of the Arduino Uno shield like a push button. The data stored at SRAM and will keep after reset.
Educational toy project to show how to write a simple object oriented state machine with your own class hierarchy.
How to Set up a MASTER-SLAVE connection between two Arduinos using I2C (Inter-Integrated Circuit) protocol.
I built the right and left mouse buttons with wall switches.
Things you should know using ESP8266 WiFi module for its safety and easiness as it's very delicate module to use.

As ESP8266 works on 3.3V and not 5v, it is important to perform this task.
Keypads are used in all types of devices, including cell phones, fax machines, microwaves, ovens, door locks, etc.
This project uses Virtual Shield for Arduino.

ESP8266 Arduino Programming Tutorial - Easy to learn, step by step.
Teaches you how to use the temperature sensor in the Arduino Grove Starter Kit.
Other than a Windows PC, USB cable and Arduino, here's a no cost approach to doing graphically rich, interactive demos for the Arduino.
