Need help with power input to DC Motor
Posted: Thu Feb 25, 2016 2:52 pm
Hi, I'm using an Arduino Uno Circuit Board with a DF Robot Motor Shield v1.2 (L298P) to drive two SPG30-20K DC Geared Motor by PWM. The power input for the motors is rated at 12V and 1.1A whereas the Arduino Board is powered by a power bank. However, the motors' speed are slow and after several consultation, I found out that a circuit have to be made to regulate the voltage and current input to the arduino board. I am at a loss on what circuit should I use and any help would be appreciated.
