Liquid Crystal Displays or LCDs are an excellent way to display characters and data in your Arduino projects. They are inexpensive and very easy to use.
In this article you’ll learn how to add LCD displays to your Arduino project, both hardwired and using the I2C bus connection. You will also learn to use a popular LCD Keypad Shield which as a 2-line LCD along with 6 push buttons.
Learn to use the popular nRF24L01 radio modules with an Arduino, using the RadioHead library.
In this article we will conduct several experiments sending data between two Arduinos with the nRF24L01. We will then take what we have learned and build a wireless joystick controller for our robot car!
Those inexpensive RF transmitter and receiver modules that you can get on eBay and Amazon are perfect when you need a low-cost method of sending one-way data between two Arduinos.
In this article you’ll learn how these modules work and how to use them in your next Arduino project.
Stepper motors are used in a variety of devices ranging from 3D printers and CNC machines to Blu Ray drives, cameras and even analog clocks.
In this article you’ll learn how steppers work, the difference between bipolar and unipolar stepper motors and how to control both of them with an Arduino.
IR Remote controls are all around us in every room of our homes. Using an Arduino we can decode and repurpose our existing IR Remotes and build our own custom remote controls
In this article you’ll learn how IR Remote Controls work and how to use inexpensive IR sensors and LEDs to do magic things with infrared light!
I’m sure you have seen those inexpensive robot car chassis kits, the ones that come with two 6-volt motors. They are great fun and very useful and they even come with a couple of speed encoder disks (those little black circles full of holes). Problem is, no one tells you how to use them!
Let’s resolve that and build a robot car with speed sensors. Along the way we’ll learn how to use Interrupts, a valuable programming technique.
The HC-SR04 Ultrasonic Distance Sensor is a staple in robotics projects. This inexpensive device is capable of measuring the distance between itself and the nearest solid object from 2 to 400 centimeters. Exactly what you need to keep your bots from driving into walls!
In this article we’ll look at this sensor in depth, including ways to make it even more accurate by compensating for temperature and humidity. There’s lots of Arduino code to be has as well, so dig in!
Controlling DC Motors is an essential skill for constructing robots and other hobby projects. An easy way to control DC motors is to use an L298N H-Bridge, an inexpensive component that you can buy from several sources.
Fear not if you’ve never heard of the L298N or if you don’t know what an H-Bridge is – in this article I’ll show you everything you need to know to start making things move with an Arduino. We’ll even construct a simple Robot Car that you can pilot using a Joystick.
So let’s get our motors running and learn all about the L298N H-Bridge!
Uno’s, Megas, Gemma’s, Nanos – the Arduino family is a huge clan, especially when you factor in the Genuino cousins and all of the Arduino clones and single-chip solutions. Each family member has its own unique personality too!
Let’s meet some of the members of the Arduino family and learn which Arduino would be best suited for your next application.
The DroneBot Workshop website will be undergoing a “facelift’ and getting some exciting new features.
These changes will be done over a period of several days. During this time the website will be operational but some features or pages may be temporarily unavailable.
I apologize for any inconvenience this may cause. Hopefully, these changes will make the site an even more useful resource for you.
I would be interested in getting your feedback on the website once these updates are completed.
Thanks for your understanding.
