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.
