i) Infrared receiver
TSOP1736
j) IC mounts
Insert the mounts for the integrated circuits (ICs) into the corresponding positions on the equipment side of the circuit board.

Attention!
Observe the notches or any other marking on the front side of the mount! This is the marking (connection 1) for the IC, which has to
be inserted later on. The mount must be inserted in such a way into the circuit board that this marking coincides with the marking on
the equipment imprint!
To prevent the mounts from falling out again when turning the circuit board over (for soldering), two opposing pins of a mount are bent and then
all connection pins soldered.
IC mount for IC1, IC2, IC3, IC4
k) Integrated circuits
Finally, the integrated circuits are inserted in the provided mounts observing the right polarity.

Attention!
Integrated circuits are very sensitive to wrong polarity! Therefore, observe the corresponding marking of the ICs (notch or dot). This
must coincide with the marking in the IC mount (the IC mount must of course also be soldered in correctly as described above!).
The parts IC2, IC4 are especially sensitive ICs, which can already be destroyed by static charge. Therefore, only grip these parts on
their casing without touching the connection pins! Integrated circuits may not be changed or plugged into the mount while the board
is live!
IC1 = L293D
IC2 = CD4093
IC3 = LM386
IC4 = 24C65
