hints
1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.
1.1 Make sure you have the right tools:
• A good quality soldering iron (25-40W) with a small tip.
• Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and
will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.
• Thinraisin-coresolder.Donotuseanyuxorgrease.
• Adiagonalcuttertotrimexcesswires.Toavoidinjurywhencuttingexcessleads,holdtheleadsotheycannot
ytowardstheeyes.
• Needle nose pliers, for bending leads, or to hold components in place.
• SmallbladeandPhillipsscrewdrivers.Abasicrangeisne.
)For some projects, a basic multi-meter is required, or might be handy.
1.2 Assembly Hints :
• Makesuretheskilllevelmatchesyourexperience,toavoiddisappointments.
• Follow the instructions carefully. Read and understand the entire step before you perform each operation.
• Perform the assembly in the correct order as stated in this manual.
• Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
• Values on the circuit diagram are subject to changes, the values in this assembly guide are correct*.
• Usethecheck-boxestomarkyourprogress.
• Please read the included information on safety and customer service.
*Typographicalinaccuraciesexcluded.Alwayslookforpossiblelastminutemanualupdates,indicatedas‘NOTE’onaseparateleaet.
1.3 Soldering Hints :
1. Mount the component against the PCB surface and carefully solder the leads.
2. Make sure the solder joints are cone-shaped and shiny.
3. Trimexcessleadsascloseaspossibletothesolderjoint.

General information
GENERAL INFORMATION

DIGITAL OUTPUT SECTION (FIG.1):
The digital outputs correspond
to Arduino lines 8, 9, 10, 11, 12
and 13. Each line drives a relay
through a transistor.
DIGITAL INPUT SECTION (FIG.2):
The digital inputs correspond to Arduino lines 2, 3, 4, 5, 6 and 7,
congured as digital input. Protection diodes secure the inputs
in case voltages higher than 5 V are applied.
Activate the input by bringing it to a low logic level (GND)
(inverse logic).

General information
ANALOGUE OUTPUTS (PWM):
Lines 3, 5 and 6 can be congured as analogue output (PWM, +5 V). With a value between 0 and 255, the duty cycle can vary between 0
and 100 %. Attention: The LED will have an inverse logic in this mode: 0 % duty cycle = LED on, 100 % duty cycle = LED off. All digital inputs
have a common ground (GND).
ANALOGUE INPUT SECTION (FIG.3):
Each analogue input (A0..A5) features a series resistor and a
protection diode.
The shield requires an external power supply (9-12 VDC).
Place jumper JP5V between the central pin and the PWR
pin. In this way, the shield as the Arduino Yun are powered
by their own power supply.
You can also use the shield with a classic Arduino board, which
can be equipped with a power supply. Place the jumper between
the central pin and 5 V pin. The Yun does not allow this because
of the higher current absorption.

Supply voltage (V) - led voltage (V)
required current (A) = series resistance (ohms)
required current (A) = series resistance (ohms)
Required resistor power handling=
voltage over resistor x current passed trough resistor
9V - 1.7V
0.005A = 1460 ohm
9V - (3 x1.7V)
0.005A = 780 ohm
(9V - 1.7V) x 0.005A = 0.036W
closest value :
use a 1k5 resistor
use an
820 ohm resistor
a standard 1/4W resistor
will do the job
Supply voltage (V) - (number of leds x led voltage (V))
How to Calculate the series resistor:
Example: operate a red led (1.7V) on a 9Vdc source.
Required led current for full brightness: 5mA (this can be found in the datasheet of the led)
LEDs in series:
Example: 3 x red led (1.7V) on 9V battery
Required led current for full brightness: 5mA
(this can be found in the datasheet of the led)
Leds feature a specic voltage
drop, depending on type and
colour. Check the datasheet for
exact voltage drop and rated
current !
Never connect leds in parallel
Leds and how to use them
An open collector output can be compared to a switch which switches to
ground when operated
