Check the kit to verify you have all the parts necessary, then get your tools ready! A board vise, soldering iron & solder , diagonal cutters, and a solder sucker (desoldering tool) if you have one.
Place the PCB in a vise to make soldering easy!
Heat up the soldering iron to 700 degrees, tin it if necessary.
Make sure the sponge is wetted.
Next, place the 1N4001 diode D1 . Diodes are directional, they only let current flow in one direction. This diode is used to protect the Boarduino from damage. Make sure the white stripe on the diode matches the white stripe in the silkscreened image below. In this picture, the stripe is on the right.
You can bend the leads a bit which will keep the part from falling out when you turn the board over.
Next, its time to place the 25V electrolytic capacitor C3. Electrolytic capacitors are polarized which means they only work well in one direction. Put it in backwards and they can explode! You can tell how to place it because the silkscreened image has a plus near one hole and the capacitor has one long lead. That lead is the positive lead. In this image, its the one on the right.
Also insert C1 which is a ceramic capacitor. Ceramic capacitors are non-polarized so you don't have to worry about putting it backwards.
Now you should soder in the 6.3V electrolytic capacitor C4 as shown. Remember its polarized so you must place the longer lead in the positive-marked hole.
Then place the ceramic capacitor C5.
Next you have to make a 3-pin header.
Use the diagonal clippers or a pair of pliers to break apart the single row header.
Take the board out of the vise and plug in a power source such as a 9V DC positive-tip wall adapter or a 9V battery with a 2.1mm barrel jack. You should see the green LED light up.
If no LED lights up check:
Is the battery or wall adapter good?
Is it positive tip?
Is the diode in correctly?
Is the LED in correctly?
Are all the parts in place?
I don't suggest continuing if you can't get the green LED to light as it indicates a problem!
Place the red LED D3, taking care to make sure the long lead is in the positive-marked hole. Also place the matching 1K resistor R3
Also place the 16.00MHz ceramic oscillator X1 (which is non-polarized) the third ceramic capacitor C2 and the 10K resistor R1
Cut another header off, this time a 6-pin piece.
Place the 6mm reset button, the 6-pin ICSP header and the 6-pin strip for using an FTDI USB cable.
Now is a good time to insert the IC.
Bend the legs gently against a table and line up the notch in the chip with the notch in the socket. Carefully seat the chip, making sure all of the legs are lined up in the socket.
Carefully remove the boarduino by slowly rocking it back and forth to release it from the solderless breadboard.
You should now try to power it up again, and you will see the green LED light. Press the reset button, the red LED should blink a few times. If you don't see the red light blink make sure the chip is in the right way.
