This is the first of a series of articles about using I2C. Today I will explain what I2C is and show you the Arduino Wire Library
We will run two demonstrations. The first demo will show you how to exchange data between two Arduinos using I2C. The second demo will describe how to control an LED on a slave Arduino with a potentiometer on a master.
Rotary encoders are versatile devices that can be used both as controls and as measurement tools.
Today I will show you two ways of using rotary encoders – as a control for a servo motor and to measure RPM on a gear motor
SD and microSD cards are a simple way to add huge amounts of non-volatile storage to your Arduino designs. In this article, I will show you how to use SD card modules with the Arduino.
I will also show you how to record and playback the motion of a servo motor.

In addition, we will build an Arduino OLED Temperature and Humidity Meter using an OLED and an I2C temperature and humidity sensor.
Learn how to transfer your Arduino Uno projects onto an ATmega328 chip so you can build a permanent version without sacrificing your Uno.
In this article I will show you a simple Star Wars Music Box project that can be built on an Arduino and then transferred to an ATmega328
In the second part of the series on building the Elegoo Smart Robot Car I will show you how to use the remote control functions.
The robot car has both IR remote control and Bluetooth remote control capabilities. Today we will learn how to use and code for both of these.
Ultraviolet Light is used in many industrial and medical applications. We also receive a dose of UV light from sunshine, and while a little UV light is good for you excessive exposure can lead to eye and skin damage.
In this article I will explain how to safely work with ultraviolet light and I’ll show you how to build a UV Index Meter that can accurately measure the level of UV and help keep you safe in the sunshine.
So grab your hat and sunscreen and follow along!

Servo Motors are a staple for hobbyists in a variety of fields. Whether you’re building model planes and boats or working with robotics you are sure to come up with dozens of applications just perfect for a servo motor.
Come and explore the use of inexpensive analog servo motors. They are inexpensive and easy to use. When coupled with an Arduino you can build all sorts of projects that move.
And if you need LOTS of servo motors we have just the thing for you – the PCA9685 16 Channel PWM controller. Using this board you can control 16 servos with just two connections to your Arduino. And you can expand that to 992 servos if you really need a lot of motors!
