Digital Alarm Clock Soldering Kit - Cyber Box Tutorials
Have you ever forgotten to charge your phone before, and have it die prior to your alarm sounding? Well you're in luck. This months soldering kit is a digital alarm clock that plays your favorite mp3 to wake you up in the morning.
First, you should refresh yourself on soldering safety!
WARNING: SOLDERING IRONS ARE HOT. SOLDERING IRONS ARE NOT TOYS. ALWAYS WEAR EYE PROTECTION WHILE USING A SOLDERING IRON.
Arduino Nano → This micro processor monitors all of the inputs (buttons) and determines which thing should happen next on the outputs (LEDs and Clock Display).
Buttons →>These momentary buttons create a connection when pressed, and give feedback to the processor.
Real Time Clock → This module also known as (RTC) is used to provide precise date/time information as long as the cr2032 battery is inserted.

Locate the 100 ohm Resistors.. Bend the leads and install into the location labeled R3.
Locate the 1K ohm resistors, there should be 2. Bend the leads on the resistors and install them into locations labeled R1 and R2.
Locate the crystal. Bend the leads, and install it into the location labeled Y1.
Locate the IC install it into the slot labeled U2. Be sure to align the notch on one edge of the IC to match the printed notch on the PCB. (it should be pointing towards the speaker)
Next, locate and install the switch and install it into the slot labeled SW7. (Make sure that the on marking on the switch is pointing toward the speaker)
Locate the battery connector and install it into the slot labeled BT1 located on the back of the board. Be sure to install the connector with the flat edge matching the printed outline on the board.
Locate the yellow .1uf capacitor, and install it into the slots labeled C1.
Locate the buttons and install them into the slots labeled SW1, SW2, SW3, SW4, SW5, and SW6. There should be 6 buttons total.
Locate the LED, and install it into the slot labeled D1, make sure that the shorter lead is inserted into the - slot and the longer lead into the +.( the one in the picture is blue, but yours should be red)
Locate the pair of Nano Sockets, and the pair of DF Player sockets. Install them into the slots labeled NANO and U1.
Locate the Potentiometer and install it into the slot labeled RV1.
Locate the speaker and solder it into the slot labeled speaker. Make sure that its + and - pins match the orientation of the label on the board.
Locate your 4 pin clock socket, and install it into the slot labeled J1. Make sure to bend the pins so that they form a right angle with the socket pointed toward the display module label.
Locate your pair of Arduino pin headers and Arduino Nano. Insert the longer pins of the header into the Arduino Nano sockets, then place the Arduino Nano on top of the headers. Solder the pins to the Nano
Insert your DF Player into the DF Player sockets, then take your adhesive pad and apply it to the rectangle surrounding the display module label. Afterward insert your clock face into the clock face header, then insert your button cell battery into the battery connector on the back of the board.
