Breadboard Jumper Wires

The Stalker ‘Bot

The Stalker ‘Bot

Gather the parts and follow the basic instructions and you can have a robot capable of following moving objects! With basic coding experience, you can also change the distance at which the robot senses moving objects or the speed the robot moves. In order to do this project, a basic robot must be built that […]

Build a Hot/Cold Detector with LEDs

[youtube http://www.youtube.com/watch?v=Y2yZ2q9G6bc?wmode=opaque&w=620&h=349] In this project, we will combine an Arduino, a Ping sensor, and a small assortment of components, to build a project that senses distances as “hot/cold.” Once built, we’ll walk through the software running our basic “sketch,” (what an Arduino program is called) and then experiment with variations of the “hot/cold” theme, all […]

Making Six Channel High Powered LED Controller Shield

This project uses IRLB8721PbF MOSFETS. These particular devices are good for the Arduino because the base current required to fully open the gate is less than 5v. I chose to use a power supply case to house this project. The built in fan will supply plenty of airflow over the heatsinks attached to the MOSFET’s. […]

XBee Pulse I/O Breadboard or Perfboard Assembly Instructions

We’re going to lead you through step-by-step instructions to build a prototype XBee Pulse I/O board on a breadboard. This board can be used to automate many things around a home and control them remotely. This design is featured in Make Vol. 30 and is used to connect a garage door opener to a mobile […]

PS/2/You LED Sign

PS/2/You LED Sign

It all started with a small LCD salvaged from an old printer. I recruited my code-savvy older brother, Adam, and we soon had the LCD displaying text from an Arduino microcontroller. This was neat, but it was inconvenient having to plug the Arduino into a computer for reprogramming whenever we wanted to change the text. […]
