GROLAB USERBOT HW01 Manuel D'installation page 9

The diagram on the previous page shows the
connec on of some different peripherals to
the UserBot shield through its female pin
headers (6).
The tac le bu on SPST (S1) is sampled on
Arduino analog pin A0; the LM35 temperature
sensor (U1) is sampled on Arduino analog pin
A1; the LED (D1) is controlled through the
Arduino digital pin 3. To control the 'speed/in-
tensity' of a device, it is required to use a PWM
Arduino digital pin (e.g. 3 and 5).
Use the +5V, +3V3 and the GND pins on Ardui-
no to power your sensors and/or devices.
Please refer to the official Arduino documenta-
on regarding power constraints on these
pins.
The UserBot shield includes an onboard bread-
board (5) that you are free to use. However, for
the diagram, we used an external breadboard
(BB) for a be er understanding.
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.
