Arduino Lego Shield
We recently tried to make this easier by developing EV3.
Arduino lego shield. In order to actually connect to the motors you have a couple of options. You can attach upto 6 RC Servo motors to EVShield. This example can be extended to use the Arduino as a sensor for the NXT and to develop your own sensors for the LEGO MINDSTORMS NXT system.
I split one of the lego wires in the middle and wired it into the motor shield directly. It can be programed in Arduino IDE with C. Finally in this photo you can see the case.
30 mA while the Lego motors need 9 Volt and pull more than 100 mA each. Then years later I traded the computer for something. The pins of the official Arduino motor shield will only align with Arduino Uno Rev.
For the advanced LEGO fan who wants to go further it really is a match made in heaven. By using an Arduino and all the various shield boards that are out there. A LEGO-compatible housing for the Arduino would be great.
But I think just an open air interface part would be even better as you dont know how high the Arduino will build with Dupont cables and maybe shields attached to it. In order to make it work with older versions of the Arduino you will need to trim a few pins off the motor shield. In this step well fix the arduino UNO to the case so it doesnt move inside it.
These allow you to control LEGO NXT Sensors and Motor. The first shield was created by Tufts graduate student Jessica Scolnic. Get it as soon as Wed Jan 5.
