Today we will learn how Hall Effect sensors and switches work. These handy devices are activated using magnets.
After that we will use a couple of Hall Effect switches to control the position of a stepper motor. Using an Arduino, we’ll build both Limit Switches and a Homing Sensor.
In this article I will show you how to control a very large stepper motor using an Arduino and a microstep motor driver module.
We will also examine how to read and interpret stepper motor specifications, and why the “voltage” rating doesn’t really mean anything.
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.
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.
Mecanum Wheels are unique wheels that allow you to propel a vehicle in any direction. Not just forward and backward, but sideways and diagonally as well.
Today, we will build a robot car that uses Mecanum Wheels. Our vehicle will also have a remote control with a joystick, a TFT display, and a rechargeable battery.
Today we will learn about electromyography by working with a MyoWare Muscle Sensor.
We’ll see how to use this device and its shields in both stand-alone mode and with an Arduino.
If you have ever required a very big servo motor, or one that rotates at an angle other than 180 degrees, then this article is for you! Today we will take a Seeeduino XIAO and a potentiometer and use them to construct a custom servo motor, using a DC gear motor.
This is a project I’m doing in tandem with Jeremy Fielding and his “self-driving go-kart” build.
Time to move up to another microcontroller, the ESP32. This amazing device has multiple I/O ports, WiFi, Bluetooth and BLE, analog inputs and outputs and many, many more features!
Today we will get started with the ESP32 by setting up the Arduino IDE as our programming environment and going through some of the example sketches.
The TB6612FNG is a MOSFET-based dual H-Bridge motor controller that can be used in place of the popular L298N.
This controller is smaller and much more efficient. Best of all, you can use it in L298N designs without changing your code!
Let’s see how to make use of this H-Bridge with an Arduino
Learn how to use Bipolar Junction Transistors and MOSFETs to interface high-current DC loads with an Arduino.
We will cover both BJTs and MOSFETs in this guide to interfacing your Arduino with the outside world.
