Learn how to use and program the Arduino Pro Mini, using an FTDI adapter and the Arduino IDE.
We will also use a 3.3-volt Pro Mini to build a battery-powered robot arm controller for the MeArm
Programming the Arduino Pro Mini
I2C Communications Part 1 – Arduino to Arduino
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.
Using Rotary Encoders with Arduino
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 Card Experiments with Arduino
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.
Using a Real Time Clock with Arduino
Introduction The Arduino is an amazing device. It’s useful for prototyping and can also be used to construct a complete project. It has an analog to digital converters (ADC), digital I/O pins, it handles interrupts and it can communicate via
Using OLED Displays with Arduino
In addition, we will build an Arduino OLED Temperature and Humidity Meter using an OLED and an I2C temperature and humidity sensor.
From Arduino Uno to ATmega328 – Shrinking your Arduino Projects
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
Elegoo Smart Robot Car Part 2 – Bluetooth and IR Remote Control
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.
Arduino UV Index Meter – Measuring UV Light
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!
DF Robot LIDAR Sensors – Getting Started with LIDAR
Introduction One advancing technology that has been impossible to ignore lately has been the work with self driving vehicles. These vehicles have gone from scientific curiosity to mainstream within a few short years and soon we’ll be seeing them as
