I need to programmatically actuate 5 pneumatic solenoids. Would it be feasible to do this by coupling a sufficient number of driver boards like one would use with stepper motors (i.e EasyDriver) to something like an Arduino Mega 2560 R3?

The solenoids I'm considering are 12vdc 3w.

  • \$\begingroup\$ What are the electrical specs (voltage and current requirements) of the solenoids? \$\endgroup\$

1 Answer 1


You could give a ULN2001 a shot: it's a pretty good jellybean driver. You can put the channels in parallel to drive higher currents (each is 0.5A).


The also have freewheeling diodes built-in so you don't have to worry about driving inductive loads like solenoid or stepper coils.
