Notes on construction, please
read carefully!
Connecting the modules
1. Press the modules into the holes of the plates. Pay attention to the
mounting direction; it should be possible to read the inscription.
2. Insert the cables as shown in the diagramme. When inserting or
pulling out a cable, only handle it by its rubber sleeve.
3. Always start with the negative pole of the battery.
4. Afterwards, you can also connect the other end of the cable.
5. Repeat step 3 and 4 for each individual cable. Only the cable for
the positive pole of the battery should not be inserted yet.
Checking
6. Before connecting the last cable to the positive pole of the battery,
carefully check all connections again.
Switching on
7. Insert the last cable at the positive pole now.
Some experiments will start as soon as
the last cable is connected. Other projects
include instructions on how to start and
operate things.
Troubleshooting – Checking the battery
Every time you want to check your battery, build the simple circuit
from the first experiment. If the LED lights up brightly, the battery is still
good. If not, the battery must be changed.
And don’t forget: connecting
