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…
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.
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.
I wanted to use more than one 28byj-48 geared motor so I modified accel stepper library to support them.
Video Tutorial on how to control large, Nema 34 Stepper motors with an Arduino, a 24V power supply and an ST-M5045 microstepping driver.
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!
I’ve always loved automation equipment! A grade school trip to a museum with a marble machine using pneumatics, sensors, servos and more had me hooked. Combining Arduino’s with mechanical devices and machined parts is just amazing. I’m working on a project using a stepper as a “feed device” and wanted to make a video experimenting with various ways to control the Arduino Stepper as well as measuring to see just how accurate it could be!
This is our very first episode of Let’s Make It. In this episode we introduce ourselves and talk a little about what is coming up. Hint: It is Arduino, Raspberry Pie, PIC Chips, Circuit Design and PC Board Manufacturing. Fun stuff!
This week we attach a keypad to an Arduino and show you how you can easily accept input. Then we build a combination door lock with that same keypad. For both projects we also use the serial LCD that we learned in Episode 5.
This is lesson 1 out of 5 where I will be teaching you the basics of XBee. In this lesson I cover general information about XBee and go through the initial setup steps.
A review of Adafruit’s inexpensive RF keyfob remote and receiver. This is by far the easiest and least expensive RF solutions I’ve seen! It’s a “turnkey” solution – e.g. it works right out of the box. It can directly control things (like an LED or transistor) or be used to trigger a digital input pin on an Arduino or Raspberry Pi!
A pieced together hack that allows for a PHP page with a button to trigger a relay on an Arduino board that acts as a button press for the garage door opener. All the code was pretty much hacked together, and has a lot of polishing to do on all parts, but as a proof of concept, it’s a start.
Measures and logs temperature and light levels. Two mode of operation: Automated – moves on its own avoids obstacles using distance sensor. Also plots the distance/sonar data into processing Manual – Manual Control using keyboard or buttons on the application. Wireless control and data acquisition: Communications using to Xbee modules. Base Xbee used to transmit data form custom processing application. Base Xbee used to received sensor data sent from the mobile data logger. Processing Application: Display data received from mobile data logger Display sonar data when in automated mode Send control data to mobile data logger using…
