GROLAB USERBOT HW01 Manuel D'installation page 11

The diagram on the previous page shows an
N-type MOSFET (Q1) being used to control
the supply voltage to a DC motor (M1).
The DC motor (M1) is powered by an external
12VDC (P1) and has PWM control via the
Arduino digital pin 5. To control the "speed
or intensity" of a device, it is required to use
a PWM Arduino digital pin (e.g. 3 and 5).
The 1 2VDC power entry
(Q1) also need to be connected to the Ardui-
no GND pin.
Use the UserBot female pin headers (6) to
connect the
MOSFET (Q1) to the respec ve Arduino pins.
The UserBot shield includes an onboard
breadboard (5) that you are free to use.
However, for the diagram, we used an exter-
nal breadboard (BB) for a be er understan-
ding.
It is crucial to pay a en on to the polarity of the different
components. A wrong connec on can damage your
components and Arduino/UserBot.
