Step 1: Solder switch, 555 timer, and decade counter

I tend to start with components that have the most legs. I find it easier to solder them when the rest of the board is clear.

*Remember the 555 timer and the decade counter are both directional so be sure to match the line on the chip to the line on the footprint

Step 2: Resistors R11, R12

Step 3: Capacitors C1-C4

Step 4: Pick LED colors you want on front, note reference designators and solder corresponding resistors to back

I wrote down which color LEDs I wanted to go where. Reference numbers match on the front and back so D1 would go to R1 and so on.

Step 5: Solder LEDs

*Make sure your LEDs are going in the right direction. Match the green dot on the LED to the line on the footprint.

Step 6: Solder battery holder

*Note: The battery holder is made of metal so it gets hot when soldering. I suggest using a silicone finger protector to hold down the battery holder while soldering it into place. Be careful touching it during and directly after soldering!

Step 7: Add batteries and turn on!
