The Elegoo Smart Robot Car V3 is an Arduino-based robot car with features like Bluetooth remote, IR remote, line following, and collision avoidance.
In the first of a three-part article I will show you how to assemble and test the Robot Car.
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!
The DF Robot 5 DOF Robot Arm kit is a high-quality robotic arm that you can assemble yourself. With heavy duty servo motors and sturdy aluminum parts this inexpensive arm is perfect for your robotics experiments
Follow along as I assemble the robot arm. I’ll also build a simple robot arm controller based on the Arduino Nano and the PCA9685 16-channel PWM module.
XOD is a method of programming an Arduino using a graphical IDE instead of writing code. In XOD you use a collection of “nodes” connected by “links” to program your Arduino.
In this second installment on our series on XOD I’ll show you some ways of improving your XOD projects by using multiple patches, custom nodes and XOD libraries.
But the real fun is that in this article we’ll also start working on a practical project – a XOD robot! So let’s get started.
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.
The HC-SR501 is a Passive Infrared (PIR) motion sensor that is extremely useful. It can be used all by itself or combined with an Arduino or Raspberry Pi
In this article you’ll learn how a PIR sensor works and you’ll build some cool projects using the HC-SR501. You can even make a motion activated camera that will tell you who is stealing your Jelly Beans!
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!
