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.
We will look at the MPU-6050, an Inertial Measurement Unit or IMU. This inexpensive device contains both an accelerometer and a gyroscope and has many applications.
We will also build an electronic level that uses an LCD and LED display.
In our second look at using the I2C bus we will build our own I2C sensor, one that has four ultrasonic distance sensors.
We’ll also learn about the protocol used by I2C communications
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
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.
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 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.
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
In addition, we will build an Arduino OLED Temperature and Humidity Meter using an OLED and an I2C temperature and humidity sensor.
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
