Schematic of Arduino PWM LED Controller Circuit. Advertisement. ... With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads ...

Yes, there is a chance to realize one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the little circuit ...

At the most an Arduino output pin can supply 40 milliamps. That’s enough to drive an LED or a pager’s vibrating motor, but anything substantial will require some help.
