But why?

Serial Communication between ESP2866-12 (NODE-MCU) and Arduino to increase the number of analog pins as my primary work.

A single Arduino Uno/Mega can carry up to 14 RS-232 boards. Each board is distinguished by ID, which is set via a DIP switch.

Make a Linux distribution that is focused on the development of Arduino and IoT. It's a Distro for Arduino.

Hello world! Yep yep, I made another simple project. This time for the KY-021 Mini reed switch. It will simply turn on and off a lamp.

This project can add two 3-digit binary numbers to turn into a 4-digit binary number. Math homework solved!

A simple method to power a servo on or off from the Arduino, using a NPN Darlington Transistor (TIP-120) and an Arduino.

Measure the unknown resistor with a simple configuration!

Demonstrates the Arduino capacitance meter and RC time constants project.

This project takes a simple RFID Reader and adds an LCD display to it.

Stream your spin bike RPM data to Power BI for real time reporting and dashboarding.

Fractal Mandelbrot with Arduino with serial output.

If you can't find a voltmeter at home or anywhere else, then this hack is for you!

Analyze digital inputs on up to six channels using the ATmega328 (e.g. Arduino Uno / Nano / Ethernet / Mini).

Communicating sound using LED Lights.

Bluetooth communication between Arduino and the PC using a small interface programmed in Processing.

Using an Arduino to toggle something like an LED light is simple in theory, but buttons don't always behave the way we think.

Tinkercad is the largest community of 3D design enthusiasts of its kind! It is an online simulator on which projects can be made.

I was looking for a way to program my Atmel ATTiny13 easily.

SwagProtocol is a header-only Arduino library that makes it super easy to add a JSON formatted communication protocol to your projects.

This is used as a clock accuracy check by triggering the minute or hour hands.
