Figure 1. Schematic diagram
Assembly and test
The assembly diagram is shown in Figure 2. The
assembly starts from the soldering the resistors
and other small components, and ending with
the assembly of electrolytic capacitors, relays
and screw terminals. The remote controlled
switch assembled from the tested components
does not require any adjustment and after
registering the commands sent by the IR
remote is ready for operation.
Entering the programming mode takes place
after pressing the corresponding button for
about 5 seconds. When it is done, the LED
corresponding to the programmed channel will
blink. This means that the switch is waiting to
receive and acknowledge the command from
the remote control that will be responsible for
switching the corresponding relay.

Correct reception of the remote command will
cause the LED to illuminate for a long time,
after which the LED blinking will indicate that
the switch is waiting for the confirmation of the
registered command. To do this, press the same
button again on the remote control. When the
correct command is received, the programming
procedure is completed and the switch returns
to normal operation. Entering the programming
mode is possible at any time during operation
of the device and is carried out independently
for each of the four channels.
