3. Resistors, and big resistors

In this part we will add the necessary resistors to the board. This will also include the large power resistors. For this part you will need the 4x 10k ohm resistors, and the 4x power resistors – which are 3.3ohm 2 watt. The 10k ohm resistors are used as a pull-down for the mosfet. The power resistors are used for limiting the current to the LEDs. Clean off the soldering iron and let’s get going.

Insert the 10K ohm resistors into R1, R2, R3, and R4. Gently twist the leads on the back to keep them in place.

Here is a look at the resistors inserted into their proper places. Flip the board.

After flipping the board, ensure the components are flush with the board.

Solder the pads where the resistors are.

Here is what the soldering should look like when complete.

Cut the leads of the resistors. Flip the board.

Insert the power resistors (the large ones) into R5, R6, R7, and R8. Gently twist the leads so the resistors will stay in place after flipping.

Here are the power resistors inserted into their proper locations. Flip the board.

Ensure the components are flush with the board after flipping.
