12. Install R3, and R8. Solder and trim the leads. Reference the parts sheet for resistor codes.
13. Install C2 a 1uF 50V electrolytic capacitor. This capacitor is polarity specific and must be
installed in the proper orientation for the system to work. The grey stripe with the negative
sign should be towards the red and green LEDs. The positive (+) lead should be towards the
outside of the board.
14. Install R6, R7, R9, and R10. Solder and trim the leads.
15. Install and solder R4 and R5. Trim leads after soldering.
16. Install and solder R1 and R2. Trim leads after soldering.
17. Install and solder the 3 push button switches labeled Reset, Next, and INC. Use care when
installing them not to have your finger behind them. The leads are sharp.
18. Install the 2 position terminal blocks. Use care to ensure they are fully seated when soldering
and that the terminal openings face outward.
19. Install and solder the USB-B connector. Go slowly on this part and make sure that the pins are
aligned properly before seating the connector. If the pins are bent it will bend the pins and
may require replacing the part.
20. Install the relay, use care to ensure it is fully seated when soldering. Trim the excess leads
once soldered. These leads may carry controlled current (AC or DC) and should be as short as
possible once installed, or protected from accidental contact.
21. Locate and install Q1, BC517. Solder the leads and trim. Use a small pair of needlenose
pliers to adjust the center lead. It will take some careful effort to align the leads and the
component may not sit all the way down on the board.
22. Install C1. Solder and trim the leads.
23. Congratulations! You have assembled your TinyTimer KickStarter Kit.
Step 4 - Programming
– Connect an ISP cable to the 6 pin header.
– Set the programmer type to match your ISP Programmer.
– Check the com port and ensure it is set correctly.
– Set the board type to Arduino Duemilanove w/ Atmega 328
– Use the Arduino IDE to burn a bootloader.
– If it complains that it can't see the chip, reverse the cable connection. If it still does not work
check your programmer settings and chip type.
– If it still fails you will need to troubleshoot the PCB. Contact
assistance.
– Send a test program to the chip and see if it runs. Use the File>Upload Using Programmer to
write to the chip.
– The test code will run the Green and Blue LEDs for 3 seconds and the Red LED for 2 seconds.
Once per second the LED will flash to indicate a heartbeat.
– Unplug the ISP and connect a USB cable to the USB Port. Verify that the system boots and
runs.
– It is now ready for customization and use in your applications.
