6. Assembling the kit
You can skip this part if you have purchased a ready-built module.
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:
2,2 k red - red - red (gold)
4,7 k yellow - violet - red (gold)
330 k orange - orange - yellow (gold)
470 k yellow - violet - yellow (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.
