Control Meccano Meccanoid


Connect a Meccanoid to your EZ-B by using an Arduino as the translator.


This tutorial uses the following controls:

4 Wire HBridge PWM Script HBridge

You may have seen some of the EZ-Robot community converting the Meccano Meccanoid to use EZ-Robot parts to add real robot features to the Meccanoid toy. While most users prefer to replace the low torque and twitchy Meccano servos with [sku:7]. Some users may wish to keep the Meccano servos to use with the EZ-B.

The Meccano servos use a modified UART protocol with 1 start bit and 2 stop bits, which is not compatible with the EZ-B natively. The solution is to use an Arduino and the provided sketch as a translator between the EZ-B and Meccano servos.

For those interested in what can be accomplished by changing the servos, check tezsmith's EZ-Robot'd Meccanoid out: http://www.ez-robot.com/Community/Forum/Thread?threadId=9320

If you wish to continue using the Meccano servos, keep reading the rest of this tutorial.
