Hello everyone,

I'm making a new project but i'm not know where to start.

I want to use ethernet so i will need a ethernet shield. but that is not the hard part, the hard part is to control all the motors.
I need to control 4 dc motors from 24V, 4 stepmotors and 5 servo's.

So my question is what boards will i need for this project.

Sorry for my bad english..., and thanks for the help.

So you want to buy stuff rather than make it?

jordyvk

no that is not nessesary, i can solder.

You need extra output pins, so use a shift register to give you 8 outputs, this will give you enough to control your 4 DC motors. You will need a transistor to drive the 24V or a H-bridge if you want to control the direction as well.

For the servos I would use the servo library and direct output from the pins.

For the 4 stepping motors you need another 8 outputs probably fed into a Puloiu driver http://www.pololu.com/catalog/product/1201

In place of a shift register you could use an MCP23S17 port expander, this will give you 16 outputs an being SPI is quite fast.

What product on that page? I can't see anything relevant.

the Mux Shield for expanding the outputs
