Hi, I have a pair of L9110 Motor driver IC's. I seem to be having problems getting both motors to move at the same time. One motor works fine but when I connect the other one the Arduino resets. I am sending both motors logic high and low as stated in the data sheet but still the Arduino resets with both running. It looks from the data sheet I need some sort of square wave but I am not sure.
see my schematic here http://www.isb.bj.edu.cn/class/ues/images/l9110.jpg
also here is a data sheet but I am sorry it is in Chinese. http://www.bricobot.ch/specs/L9110.jpg
Please, any help would be welcome.
