This book is about using the electronics modules produced by eLabtronics. These electronic building blocks – especially the Multi Purpose Module – can perform functions limited only by your imagination. The Multi Purpose Module does not require user software reprogramming to perform different functions – instead you need adjust only two on-board potentiometers (pots) and set a 5-way DIP switch to the correct positions. That makes set-up very quick and easy. The Multi Purpose Module is available in different forms – it can be a voltage switch, a timer, a device that outputs a pulsing signal… and so on. The hardware remains the same – just the software has been pre-altered. So have fun – wiring and set-up are dead-easy and you don’t have to do any programming, let alone printed circuit board soldering! The approach is perfect for people who want quick electronic results – inventors, car modifiers, students, and those just learning about electronics.
