*Single DC power supply for both Arduino and motors:
Plug Voltage < 12V into the DC jack on the Arduino or the 2-pin EXT_PWR block on the shield.
Jumper ON
*(Recommended) Arduino via USB and motors via DC power supply:
Arduino plug in the USB cable.
Then connect the motor supply to the EXT_PWR block on the shield.
Jumper OFF
*Arduino Jack and motors via DC power supply:
Plug in the supply for the Arduino into the DC jack.
Connect the motor supply to the EXT_PWR block.
Jumper OFF
Warning:
DO NOT supply power to the EXT_PWR input when jumper is in place.
It may damage the motor shield and also your Arduino!
The shield offers below features:
The shield comes with a pulldown resistor array to keep motors switched off during power-up.
The on-board LED indicates the motor power supply is Okay. If it is not lit, the motors will not run.
The RESET is nothing but Arduino’s reset button. It just brought up top for convenience.
