Introduction Hello everyone, I hope all of you are doing well. This article gives guidance on constructing a circuit to control a stepper motor using an Arduino UNO and the ULN2003 motor driver. Listed below are three circuit diagrams along with their corresponding codes. You are free to choose and customize any of these circuits […]

The ancient art of sailing can be very intimidating for the uninitiated given the shifty nature of wind. To help understand the interaction of wind direction and board orientation, [KifS] designed a hands-on sailing demonstrator that lets students grasp the basics before setting foot on a real sailboat. The demonstrator uses a potentiometer as a tiller to

Coil winders are a popular project because doing the deed manually can be an incredibly tedious and time consuming task. After building one such rig, [Pisces Printing] wanted to find even further time savings, and thus designed an improved, faster version. At it’s heart, it’s a straightforward design, using a linear rail and a leadscrew driven
Stepper motors are not smooth – they move in “steps”. Different motors have a different number of steps to make one complete rotation. You use software to step the motor forward or backward at different speeds. There are two kinds of stepper motor bipolar and unipolar – Unipolar will have five or six cables coming
Whether we care to admit it or not, motors can be found all over in our everyday lives; they just tend to be hidden. Motors are present in cars, printers, computers, washing machines, electric razors, and much more. However, there are a number of people (which until recently included myself) that would be uncertain of
Hi guys, I made an automatic 3D Printed Pet Feeder (or just dispenser, but I use it to feed my dog). I 3D modelled all that project. U can print it by yourself. All parts are down there. Basically how it works, is u type in two Feeding Times, for example 8:30 and 17:30, then

Many of the projects we feature on Hackaday are motivated by pure greed. Not on the part of the hacker, mind you; but rather the company that’s charging such an outrageous price for a mass produced item that somebody decides they can do the same thing cheaper as a one-off project. Which is precisely how [Bryan
This is part one of a two-part project. For part one, we will focus on IR remotes and signaling, as well as IR reception and decoding. Using IR (InfraRed) radiation to control electronic devices is widely accepted and implemented. IR devices are routinely used in alarm systems, automatic door openers, and similar applications. This project
It is a well known fact that Stepper motors are awesome! The only downside is that they can be a bit trickier to get going than servos and plain old DC motors. If you are interested in the inner mechanics and theory of stepper motors, check this excellent post on PCB heaven. If you happen to have one
Stepper motors are great for accurate positioning because they move in discrete steps – a feature that makes them very appropriate for CNC software control. But every once in a while you have an application where you need to press a button and rotate some kind of a jig at a preset angle or move
