Step 3Trimmer and resistor
Take the 10k trimmer (I used also a 4,7k and it works good) and connect the central pin to the display on the VO, the other two pins to the pin VSS and VDD of the display
Then take the 100ohm resistor and connect it between the pin BL+ and VDD, and then connect the pin BL- to VSS with a wire.
