So you want to build your Arduino project in hours and not days. A-blocks delivers you ready-to-use plug and play modules for your project.
If you want to add a rfid reader you can spend days selecting a reader, trying to understand complex datasheets, reading forums and making breakout and prototype boards. Your other option is just to use the plug and play rfid reader from a-blocks and you have it up and running in minutes.

A rfid reader is not the only module we have. We have modules for wireless connections, internet connections, displays, servo motors and many more.

Just think about it. You have an idea for a project. With A-blocks you can build and use your project the same day. It is not just our digital modules. The a-blocks interface shield also has 5 phidget compatible analog inputs. This offers you a way to add sensors by just plugging them in. So you want to measure temperature and humidity? Just plug in the temperature and humidity sensor. And it it just as easy to add a light sensor, sound sensor, or movement sensor. We have so many sensors you just have to take a look.
For both the digital and analog ports we have also control blocks. So you can also add switches, knobs, sliders and other interface blocks.
