Hi Tom
Thank you for the reply, as yet I haven't purchased either the Arduino mega or the 16 channel relay board so would be open to recommendations on suitability. Bit of a strange project but looking to make an adjustable putting green. I have worked out a suitable frame and base material and am looking at using 8 high force linear actuators to manoeuvre the green for various slope degrees based on length of time the actuator is set at high. I also want to use a Nextion screen to give a nice gui. As a newbie the mechanical side I am happy with but will have to put in quite a few hours work to get to grips with the coding.
Any help or advice welcome
Thanks
Andy
