How to use 16×2 LCD with Arduino || Arduino tutorial

In this video I’m demonstrating how to start using a 16×2 LCD with an Arduino. The first example displays a static text message and number of seconds since Arduino reset. The next one covers modification of my Arduino ohmmeter project to display data on the 16×2 Hitachi HD44780 LCD. It is a step by step tutorial, which will walk you through wiring the alphanumeric (text) LCD to work with Arduino Uno. You will also learn how to write a sketch (program), which lets you control the liquid-crystal display with the Arduino.  

How to Connect an I2C Lcd Display to an Arduino Uno

I²C (Inter-Integrated Circuit), pronounced I-squared-C, is a multi-master, multi-slave, packet switched, single-ended, serial computer bus invented by Philips Semiconductor (now NXP Semiconductors)  

How to Connect an I2C Lcd Display to an Arduino Uno Tutorial

How to Set Up and Program an LCD on the Arduino

In this video, I briefly show you how to connect a 16×2 LCD to an Arduino. After that, I go in-depth into which functions are available in the LiquidCrystal library to program it, and show you what they look like on the LCD. I also explain where and how to use each function in your program.  

Arduino LCD Tutorial | How To Control An LCD

In this Arduino LCD Tutorial we will learn how to connect an LCD (Liquid Crystal Display) to the Arduino board. LCDs like these are very popular and broadly used in electronics projects as they are good for displaying information like sensors data from your project, and also they are very cheap.  

Arduino using a A4988 board to control a stepper motor

Quick video on how to test a Reprap controller board and stepper motor  

Stepper Motor Drivers with Arduino CODE – DRV8825

Well, here’s a video shows how to actually control one of these motors in your project using a stepper motor driver IC – the DRV8825  

Controlling DC Motors with the L298N H Bridge and Arduino

The L298N Dual H-Bridge Motor Controller is an inexpensive device which allows you to control two independent DC motors using 5 volt digital logic signals, such as the digital output pins of an Arduino. The L298N can also be used to control a single stepper motor or two sets of LED lighting strips.   In this tutorial we’ll learn how to control two 6-volt DC motors with the L298N.   First we will enlighten ourselves by learning a quick bit of the history of DC motors and discovering how they actually work. We will also learn what an “H-Bridge” is,…

Arduino BIG Stepper Motor control. Rotary Axis for milling machine.

Wiring connections – Arduino Pin 8 to stepper driver pulse +5V – Arduino Pin 9 to stepper driver direction +5V – Arduino Ground to stepper driver signal ground Pulse -ve, Dir -ve, enable -ve – Arduino +5 volts to on/off switch to stepper driver enable +5V   Helpful hints: 1. Pick the size of motor you need for the torque/power you need. Don’t know? FIND OUT! 2. Determine the voltage and current of the stepper motor. 3. Determine the stepper motor driver that will power your stepper motor with some extra fudge factor (this stuff is cheap). Big Easy driver…

SUPER Fast Arduino Servo! ClearPath! WW120

ClearPath Servos are AMAZING! Using them with an Arduino UNO to get over 1,100 IPM rapids on a linear stage!  

Control High Voltage Devices – Arduino Relay Tutorial

Warning: We will use High Voltage which if incorrectly or improperly used could result in serious injuries or death. So be very cautious of what you are doing because I take no responsibility for any of your actions.   In this tutorial we will learn how to Control High Voltage Devices using the Arduino Board.  

Homemade DIY CNC – ClearPath Servo Motors used on KR33 CNC

Many have asked what motors I’m using on the KR33 Mini CNC so I wanted to do a video specifically on the topic. The motors are ClearPath Digital Servo motors by Teknic. I communicate with them the same way that I’ve done with stepper motors, with step and direction commands. The speed and power is fantastic. The servo motors power doesn’t fade with speed like steppers do.  

Modified accel stepper library for 28byj-48 geared step motors

I wanted to use more than one 28byj-48 geared motor so I modified accel stepper library to support them.  

Use Arduino to Control a Large Stepper Motor! Part 1

Video Tutorial on how to control large, Nema 34 Stepper motors with an Arduino, a 24V power supply and an ST-M5045 microstepping driver.  

Why you should buy an Arduino Leonardo

The Arduino Leonardo is awesome. The newest dev from the Arduino team features USB functionality (read: stream Arduino data directly into any windows/mac app!), more pin power (more PWM, more I/O!) and is the cheapest version yet at $24.95!
