Discussions > How to run multiple dc motors through firefly


I want to run 8 dc gear motors 5v through grasshopper as i want multiple turns continuous rotations in both directions. i can use stepper motors but the shield is currently not available in my area. i read this blog entry but i dont know if building an hbridge circuit will run multiple motors through grasshopper. And also i mistakenly bought L293D h-bridges instead of L293NE so would this circuit work with them?
I would be very grateful for your help.
