Alarm Clock
Educational Soldering Kit
A practical clock kit with an alarm function. Outfitted
with a straightforward LED display and brightness
regulation circuit, conditional to the ambient light, the
Alarm Clock maintains operation even when the
power supply is cut.

How to use

You can control the alarm clock with the use of two
buttons: MODE and SET. Diagram picturing the use of
the clock is shown on Figure 3.
While the clock is working, pressing and holding the
S2 button will turn the alarm on/off. When the alarm
is activated, the display will show the set time for a
few seconds.
The diode set by the minute number shows whether
the alarm is on or off. If the alarm is active, the diode
is on.
After the alarm starts, pressing either of the buttons
shuts it off, activating the snooze function (the alarm
diode starts flashing). After the alarm starts again,
pressing either of the buttons starts the snooze
function, etc. Really great function for the laid-back...
To turn off the alarm and the snooze press and hold
the S2 button. The alarm will also turn off after
