ULN2003

The ULN2003 is one of the most common motor driver ICs that houses an array of 7 Darlington transistor pairs, each capable of driving loads up to 500mA and 50V. Basically, a Darlington pair is a pair of transistors, where the second transistor amplifies the output current of the first transistor. The ULN2003 IC is needed to drive the motor with an Arduino, but they come in convenient and cheap driver boards that are readily available complete with indicator LEDs. So it’s better to grab one of these rather than breadboarding the IC itself.

Arduino CNC Thermocol Cutter

“In this project, I’d like to share how to build a 2-axis thermocol/ polystyrene cutting CNC machine with its frame and supports made of electrical wire casing/duct and 3D printed parts. Basically it is a thermocol cutting tool …

Non-Split Flap Digital Clock

“I developed a new clock mechanism to address the issues present in existing mechanical clocks. Famous split-flap displays exhibit undesirable parting lines in the text, and their display surfaces cannot be tilted as they rely on gravity. Numechron-type clocks feature …

Make a simple 3D Hollow clock (Arduino Nano and 5V Stepper)

“Hi, in this project I will show you how I made this great-looking 3D-printed Hollow clock. Hi, in this project I will show you how I made this great-looking 3D-printed Hollow clock. I saw this project on Thingiverse a few …

Haptic compass belt

“I’ve always wanted to build a compass belt! The idea is to attach a couple of vibration motors to a belt, use a compass sensor to find north, and then to let the motor that points north vibrate! Wearing …

Solar Powered Mechanical Light Sensitive Flower

“This project is the design of a mechanical flower which is sensitive to light and moves in the direction of light. I started off in my mind to design a compact one but as always things don’t necessarily go …

How to Make a Simple Seismograph

“In this tutorial, I present the construction of a seismograph with simple materials and available to anyone. Since I had the mechanical support left over from the previous project (Music box), I built the mechanical gears using the same components …

Arduino Rolling Ball Kitchen Timer

“I have always been facinated by rolling ball clocks and when I saw JBV Creatives “Rolling Ball Escapement” demo I just had to build it into a working project. This is a general purpose kitchen timer and uses a 3D …

Rotating Moon Lamp

“Have you ever wanted a part of the night sky right next to you? This Rotating Moon Phase Lamp will do just that! It’s a moon lamp that has a lithophane moon cover and a stepper motor inside to …

An Experimental Magnetic Loop Driven by Android and a Stepper Motor

“So I am a big fan of Kevin Loughin’s YT channel and also of Mag Loops having already bought an unwanted YouLoop on Facebook Market Place. Watching this video Ham Radio - Magnetic loop transmitting antenna overview and details inspired …

ESP32 IOT based Home Automation Project

“Hello friends In this post we will learn how to make a ESP32 IOT based Home Automation project using Blynk 2.0. This days we here lots about IOT, IOT stands for Internet of things. In this project we build …
