The controller has been mounted on a board with
the
arrangement of the components as shown in Figure 2.
Start mounting according to general principles,
first
solder the lowest components -
resistors, and end with
the highest ones - connectors. Once
the device is
assembled, the ICs must be placed in their sockets and
a 12 V power supply must be connected to the VCC
input. The controller itself draws current, in the order
of several milliamps, but the current capacity of the
power supply should be adjusted to match the
current drawn by the ICs.
The sequence programming mode is entered by
pressing and holding down the S1 button. This state will
be signalled by a longer illumination of the LED. The
programming itself is carried out by setting the selected
combination (on and off outputs) with switch SW1 and
confirming it with button S1. Setting the SW1 switch to
the "ON" position turns on the respective channel
(lights up the diode connected to the output) and in the
"OFF" position turns off that channel. When the S1
button is pressed, a brief flashing of the D1 diode
signals that the state set by switch SW1 is being
stored. Record the next steps in the sequence to be
created in the same way. When the microcontroller
memory is full of all 124 steps, the circuit will light the
LED longer each time the S1 button is pressed. Once
you have saved all the required sequences, you need
to decide if you want it to be
played once or repeated
in a loop. Ending the sequence teaching procedure
