assembly
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 flux or grease.
• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot
fly towards the eyes.
• Needle nose pliers, for bending leads, or to hold components in place.
• Small blade and Phillips screwdrivers. A basic range is fine.
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 leaflet.
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

PCB

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 specific 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
