How Should I Use Arduino?
If you are a beginner with Arduino, Arduino learning kits on our website www.adeept.com would
be a prefect step into this fantastic field!
Two types of Arduino board are used in this car kit: Adeept UNO R3 board and Arduino Nano
board.
Power
The Arduino/Genuino Uno board can be powered via the USB connection or with an external
power supply. The power source is selected automatically.
External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The
adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack.
Leads from a battery can be inserted in the GND and Vin pin headers of the POWER connector.
The board can operate on an external supply from 6 to 20 volts. If supplied with less than 7V,
however, the 5V pin may supply less than five volts and the board may become unstable. If using
more than 12V, the voltage regulator may overheat and damage the board. The recommended
range is 7 to 12 volts.
The power pins are as follows:
Vin. The input voltage to the Arduino/Genuino board when it's using an external power source
(as opposed to 5 volts from the USB connection or other regulated power source). You can supply
voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied
with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the
board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage
your board, which is not recommended.
3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
GND. Ground pins.
IOREF. This pin on the Arduino/Genuino board provides the voltage reference with which the
microcontroller operates. A properly configured shield can read the IOREF pin voltage and select
the appropriate power source or enable voltage translators on the outputs to work with the 5V
or 3.3V.
