6. Assembling the kit
You can skip this part if you have purchased a ready-built module or device.
6.1. Preparation
Put the sorted components in front of you on your workbench.
The separate electronic components have the following special features
you should take into account in assembling:
Resistors
Resistors reduce current.
The value of resistors for smaller power ratings is indicated
through colour rings. Every colour stands for another
figure.
Carbon film resistors have 4 colour rings. The 4th ring
(given in brackets here) indicates the tolerance of the
resistor (gold = 5 %).
Value:
Colour rings:
1 k
brown - black - red (gold)
1,5 k
brown - green - red (gold)
10 k
brown - black - orange (gold)
Trimm-potentiometers
Trimm-potentiometers (abrv. "trimm-pots") are resistors
which allow the value of resistance to be varied and that
way to be adapted to the particular demands. In the
middle they have a small slot into which a small
screwdriver can be put in order to vary the value of
resistance. The maximum value is printed on the housing.
Depending on the mounting situation trimmpots with a lying or a
standing package are used.
