Build robots and contraptions! Experiment with mechatronics using
Arduino and LEGO Mindstorms NXT!
Use the Bricktronics Megashield Kit to connect up to six LEGO NXT
motors and four LEGO NXT sensors to an Arduino Mega.
* Supports up to six LEGO NXT motors, and reading their encoders
* Supports up to four simultaneous LEGO NXT sensors
* Supports LEGO NXT touch sensors on all four sensor ports
* Supports LEGO NXT 2.0 color sensor on all four sensor ports
* Supports LEGO NXT ultrasonic sensor on all four sensor ports
* Uses standard LEGO NXT cables
* Tested compatible with the Arduino Mega 2560, but should work on
many other Arduino compatibles
Solder the kit, download the easy-to-use Arduino library, check out
the examples, and start building!
We now have pre-assembled Bricktronics Megashields available for
purchase. Use the Options box to select an Assembled shield and it'll
arrive ready to go.
SEE IT IN ACTION!
READING A COLOR SENSOR WHEN A BUTTON IS PRESSED
The kit contains a Bricktronics Megashield printed circuit board, ten
custom injection-molded NXT-compatible sockets, a 2.1mm DC power
supply socket, eight jumpers, three 0.1 uF ceramic capacitors, a 6mm
reset pushbutton, six 100 k resistors, three 100 uF electrolytic
capacitors, three 10 uF electrolytic capactitors, three L293D H-Bridge
motor-driver chips, one PTC over-current protection fuse, and headers.
The Bricktronics Megashield can be purchased in two kit configurations
-- Pre-assembled, or as a solder-it-yourself kit. Neither option
supports the "stacking headers" that many Arduino shields use to
permit stacking multiple shields (due to interference between the
motor ports and the stacking headers), which means that you must place
the Megashield as the top shield of your stack.
WHAT YOU NEED
The Bricktronics Megashield Kit connects an Arduino Mega to LEGO NXT
motors and sensors. Arduino, motors, sensors and NXT cables are not
included. The Mindstorms NXT 2.0 set includes three motors, two touch
sensors, one color sensor, one ultrasonic sensor, and a variety of NXT
Motors take more power than can be supplied by a USB cable (USB is
limited to 500 mA maximum). The LEGO NXT motors typically need about
600 mA each, but under heavy loads can require up to 1000 mA peak per
motor. Our 9V 2A wall adapter works great for a couple motors, but any
2.1mm 9V adapter with sufficient current should work. Driving 5 or 6
motors with heavy loads will require a beefy power supply on the order
of 3-5 amps. If you want to power your creations on the go, our 6 AA
battery pack works well
If you don't buy the pre-assembled version, the Bricktronics
Megashield Kit is a through-hole soldering kit. It requires basic
soldering skill. At a minimum, you'll need a soldering iron, solder,
and a diagonal cutters. Clear instructions are available at the
Bricktronics Megashield project webpage.
It usually takes under an hour to build, but it may take more or less
time depending upon your experience with soldering.
OPEN SOURCE HARDWARE
This kit is open source hardware. We make the hardware source files
like the schematic and the pcb files available for anyone to use as
long as they credit us and release any modifications as open source
hardware. The schematic and pcb files are available on the
Bricktronics downloads page .
A portion of the profits of this kit go to John Baichtal, an author of
the Make: Lego and Arduino Projects book.
