do you create the program for plc? with code for plc i could understand the code for arduino!

A friend of mine and I were discussing with one of our professors about the possibility of using an arduino board to manage electromagnets, and put small magnetic strips in the knex balls. It would have been a heck of a lift but the knex tend to melt haha. One more thing, when you built metropolis, did you have to buy more green rods/white connectors?

I'm 22 years old. Yeah I like solidworks because compared to other CAD programs, this one is very 'easy' to get into. As for the arduino, it's great too. I'm thinking of getting one for future knex projects :P

How old are you? I think it's really cool that you know solidworks/arduino microprocessor information. I had to use both of those for a first year engineering project at university
