This data-logging shield for the Arduino makes saving data to files on any FAT16 or FAT32 formatted SD card really easy. The included Real-Time Clock timestamps all your data with the current time, so that you know precisely what happened and when!
Step #1: Gather your Materials.Next
- Check to make sure you have all of the necessary components to build the data logging kit.
Step #2: Insert the 10K Resistor.Next
- Insert the resistor with color bands Brown-Black-Orange into the location marked R5.
- Resistors are not polarized, so it does not matter which direction you insert them in.
- Turn the board over, and then solder the leads.
Step #3: Tip: Clip your leads!Next
- Make your soldering life easier by trimming the leads of the components after you solder them in.
Step #4: Insert the 1.0K Resistors.Next
- In locations R3 and R4, insert the two resistors with the color bands Brown-Black-Red.
- Turn the board over, and solder the resistors in. Then clip the leads.
Step #5: Mount the SD Card Holder.Next
- The SD card holder has two humps that snap it into place on the circuit board.
- You should be able to feel it fit into two grooves and sit snugly on the surface.
- On the sides are 4 tabs. Solder these tabs to the circuit board by first heating up the tabs, and then applying solder. The holder shouldn't move once it's been soldered in.
- Now all you need to do is solder the leftmost 7 tabs to the circuit board. It is unnecessary to solder the remaining three.
Step #6: Insert the 2.2K Resistors.Next
- In locations R1 and R2, insert the two resistors with the color code Red-Red-Red.
- Solder these two resistors in, and then clip the leads.
Step #7: Insert the Ceramic Capacitors.Next
- The two small, yellow ceramic capacitors are not polarized, so it does not matter which direction you insert them.
- Insert them into locations C2 and C3.
- Solder them in, and then clip the leads.
Step #8: Insert the Electrolytic Capacitors.Next
- Electrolytic capacitors are polarized, so it is important to insert them properly.
- The longer lead is the "+" lead, so make sure you enter this lead into the hole marked with the "+.
- Insert them into locations C1 and C4. Solder them in, and then clip the leads.
Step #9: Next
- Insert the 3.3V Regulator.
- In location IC1, insert the regulator with its flat end matched up with the flat side of the silk-screened image on the circuit board.
- Solder the leads in, and then clip them.
Step #10: Insert the 8-pin Socket.Next
- The socket has a notch on one end. This notch must match the one in the picture silk-screened onto the circuit board.
- Make sure the socket is flush with the circuit board when you turn it over to solder.
- Once the socket is soldered in, you can insert the IC into the socket.
Step #11: Insert the IC3 chip.Next
- The longer chip will be inserted into location IC3 without a socket. It is important to make sure that the end of the chip with the notch matches up with the the notch on the silk-screened image.
- Turn the board over and solder the chip into the circuit board.
Step #12: Soldering the Battery Holder.Next
- Deposit a bit of solder on the center tab of the location marked BAT.
- Now you can insert the metal battery holder and solder it in.
Step #13: Insert the Reset Button.Next
- The reset button is inserted into the location marked RESET.
- Press the button all the way into the circuit board. Turn the board over and solder it in.
Step #14: Insert the LEDs.Next
- In location LED1, insert the green LED. The longer lead of the LED should be inserted into the hole marked "+" on the circuit board.
- In location LED2, insert the red LED. Just as with the green LED, insert the longer lead of the LED into the hole marked with the "+".
Step #15: Insert the Watch Crystal.Next
- In location Q1, insert the small metal cylinder. The crystal is not polarized, so you can insert it in any direction.
- Solder it in, and then clip the leads.
Step #16: Clip your headers.Next
- From the 36-pin header, clip two 8-pin and two 6-pin headers.
Step #17: Soldering the Headers.Next
- Insert the longer end of the headers into the female headers on the Arduino.
- Place the shield on top of the the shorter leads of the headers.
- Solder every pin of the male headers, and you will be finished.
Step #18: Finishing Touches.
- Insert the included coin-cell battery, and you are finished.
- You can remove the shield from the Arduino, or keep it attached to the Arduino.
