WiFi Stepper Motor Controller

WiFi Stepper Motor Controller

The WiFi Stepper is exactly what its name would imply – a board that lets you control a stepper motor via WiFi. Its full-featured web-based interface gives you complete control of your motor, and it can support steppers of all sizes up to 85 volts at 10 amps!

Today I’ll demonstrate how to use this versatile board. I’ll hook it up, learn how to use it and even run a simple Bash script on a Raspberry Pi to demonstrate how to incorporate it in your programs.

Experiments with the RCWL-0516 – Doppler Radar Distance Sensor

RCWL-0516 Microwave Proximity Sensor

The RCWL-0156 is an inexpensive yet useful proximity sensor that can be used on its own or with a microcontroller like an Arduino Uno.

The device is unique in that it uses microwaves and Doppler Radar to detect moving objects

In this article I will show you how the device works on its own and how we can add an Arduino (or two) to create some useful projects

Pixy2 Camera – Object Recognition with Arduino & Raspberry Pi

Pixy2 Camera

The Pixy2 is an amazing camera that is capable of object detection, line tracking and barcode reading. All this in a tiny and very affordable little package

In this article I’ll take a look at the Pixy2. I’ll show you how to hook it up to an Arduino and how to train it to recognize objects. You wil see how easy it is to work with this camera to add vision sensing to your next project

Arduino UV Index Meter – Measuring UV Light

Arduino UV Index Meter

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!

Powering Your Electronics Projects – Voltage Regulators and Converters

Power For Your Electronics Projects

One of the most important, yet most overlooked, aspect of building a project is designing a method of giving it power. Power sources like batteries and AC adapters are only half of the answer, you still need to provide logic-level voltages to safely power your devices.

In this article we will look at several methods of providing safe regulated power for your electronic designs.

Using Servo Motors with the Arduino

Servo Motors with Arduino

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!

Getting Moving with XOD – Robot Car Part 1

XOD Robot Part 1

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.
