Stepper motor wiring tutorial
Occasionally you may come across an old stepper motor salvaged from a printer, or an ancient floppy drive. If you are lucky, there will be a part number on the motor and after some digging around, you will come up …

While testing a new circuit on a breadboard, my good old Arduino Uno suddenly released its “magic smoke” with a loud pop and stopped working. On a closer inspection, I saw that a small crater had appeared on the 5 …

In one of my rather frequent eBay visits, I came across a nifty little joystick module, much similar to the analog thumb-stick on the PlayStation 2 controllers. The module is very easy to use with an Arduino uno and only …
Daisy is an old “Discovery Kids” projection alarm clock turned into an autonomous obstacle avoiding bot. The brain is an Arduino Mini. Two small servos, modified for continuous rotation, are used for a differential drive and a combination of 3 …

This is a side project from my endeavor to program an Arduino Uno wirelessly (over Bluetooth) using a cheap HC06 JY-MCU Blueetooth Module I got from eBay. In order to kick off the Arduino bootloader and upload a new sketch, …
Breadboards and hook-up wires are great for prototyping and testing out basic circuits. At some point though, you will want to create something more permanent and robust. Robots move around, bump into things, shake and vibrate and wires tend to …
In a previous post I shared my notes on how to connect an Arduino to an Android phone using the the popular and cheap HC-06 Bluetooth module. In that example I used the Bluetooth module with its default settings. That works fine, but …

I am working on circuit that will allow me to program my Arduino boards (I have an Arduino Uno and a couple of Arduino Pro Minis) over a wireless Bluetooth connection. I am planning to use my cheap and easy to find …
