If not, or if it has been a while, you may also want to look at pages 2 and 5-7 of the [[Bulbdial|Bulbdial clock]] assembly instructions, which go over basic tools and technique. And, if you really are a beginner, there are plenty of good tutorials on line, like [http://www.instructables.com/id/How-to-solder/ this one]. |

Solder the long lead of the LED to the lighter wire, and the short leg to the darker one. Your wire pair colors may vary, but here, the yellow wire goes to the long lead and the blue one to the short lead. You can trim both the leads (as shown), or leave one long to stick into the top of the pumpkin. |

− | + | Follow along with the circuit diagram, as we populate the ATtiny2313 board. The board provides some of the necessary connections, such as pin 20 to power and pin 10 to ground. It also provides prototyping areas for us to hook up the remaining parts to. | |
+ | First, install the socket, matching the half moon notch in the socket to the shape on the board. Solder the socket in place. | ||

Use the next zero-ohm jumper to connect the second hole way from pin 13 (labeled PB1/AIN1/PCINT1) to the top prototyping row below. These will form the two range options for the servo motor. |
The third zero-ohm jumper connects the left-most prototyping column to VCC_3 directly to the right. Connect the final jumper from the middle prototyping column to GND_3, also directly to the right. | The third zero-ohm jumper connects the left-most prototyping column to VCC_3 directly to the right.

Orientation is critical: Make sure that the half-moon indentation at one end of the chip matches that on the socket and PCB. Insert it firmly, as far down into the socket as it will go. |
