This great video shows you how easy it is to wire-up a potentiometer to an Arduino microcontroller board, read the resistance value, and then control a standard hobby servo in unison. The simple software reads the analog to digital converter to read the pot value and then does a simple calculation to arrive at the […]

When you need to read and log a device’s location via GPS, things can get complicated very quickly. There’s arcane things needed like high frequency radio receivers, complicated triangulation calculations, and other thing generally beyond the ability (or desire) of someone just wanting to build a project. That’s why using a pre-made GPS module is […]

If your project calls for producing sounds or even pre-recorded voices you will really like this module! If you were to try to design your own sound output circuit, you’d have to delve deeply into analog calculations and amplifier designs, which is definitely not “modular electronics”. However, this handy, inexpensive mp3 module lets you records […]

Field Programmable Gate Arrays, or FPGAs, are high-speed chips which are filled with thousands of structures called logic blocks. These blocks allow you to build, using a specialized electronics programming language like Verilog or VHDL, a custom circuit on the chip to do whatever you need done in your circuit. The FPGA offers much of […]

The Parallax Basic Stamp series really started a revolution many years ago when the Basic Stamp was introduced. Since then, the Basic Stamp product range has been increased to include the BS2 and a number of other handy pre-built electronic modules that are designed to work with the Stamps. The BS2 is a self-contained microcontroller […]

This is a neat project that shows some of the really cool stuff you can do with pre-built, easy-to-use modular electronics. The concept is simple: the machine uses an inkjet printer module to print text or graphics on blank wooden “nickels”. The whole thing is controlled with a Basic Stamp 2 and a Propeller chip. […]
