Andrew - looks like I have resolved the problem. It suddenly started working. Looks like I have a bad joint somewhere.

Thanks for all your help - much appreciated.

Andrew - thanks for checking it out.

The serial port does give output and I've had already checked the motor in the manner that you suggested.

I'll do some further tests.

Andrew - the shields is connected to a Wemos D1 mini. VM and GND are connected to a 7.4V LIPO and the motor is a lego train motor connected to pins A1 and A2. Nothing is getting hot.

I connected the motor shield as illustrated in the diagram and run the test library but the shield does not start the motor.

I've tried an I2C scanner but it cannot find any devices.

Can you help?

Regards

Allan
