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.
